The invention relates to radio engineering and computer science and is intended for parametric estimation of the law of distribution of a multipackage messages in multi-media (satellite, radio relay, tropospheric) radio and in the media processing and data transmission in local area networks (LAN), combined in a digital telecommunication network (TCN).

A device for parametric estimation of the distribution containing the input amplifier, the memory block, the block check consent, the control unit and the synthesizer distribution function (see ed. St. USSR №1024935, G 06 F 15/36, G 06 G 7/52, 1983, bul).

The disadvantage of this device is the low level of performance when it is used to estimate the distribution of a multipackage messages (IPU) in TCS integration services, due to the need enumeration of the set M combinations of parameters for the distribution of message flow consisting of a set of packages.

A device for parametric estimation of the distribution of message flows that contain the input amplifier, the power calculation unit calculating average values, the block type definition of the distribution, the evaluator distribution and control unit (see RF patent №2094844, G 06 F 17/18, 1997, bul).

However, this device and EET narrow scope, because it is impossible to estimate the distribution of the heterogeneous (mixed) flow map, taking place in TCS integration services and is caused by the presence of the source of information, outstanding as expressed independent single informational messages to the user (COI), and packs of COI, the length of which is distributed according to a geometric law. In this case, the approximation of the real statistics of incoming flows COI impossible to reduce them to the three classic versions message flows.

The closest to the technical nature of the claimed device (prototype) is a device for parametric estimation of the distribution of message flows (see RF patent №2165100, 7 G 06 F 17/18, 2001, bul)containing the input amplifier, the input of which is filed binary pulse sequence, the block parameter calculation unit calculating average values, the block type definition of the distribution, computer distribution, control unit, and the unit of analysis of the intensity, and the clock output control unit connected to the clock input of the transmitter distribution, Abdoulaye and control outputs of the control unit are connected respectively with boleushim and managing inputs block parameter calculation, an information input connected to vyhoda the input amplifier, the first and second information outputs of the computing unit parameters connected respectively to the first and second information input unit for computing the average value, the first information output of which is connected to the first information input of the transmitter distribution and with the input of the block type definition of the distribution, the first, second, and third modification, the outputs of which are connected respectively to the first, second and third modification to the inputs of the transmitter distribution, the second information input of which is connected with the second information output unit for computing the average values, the output of the transmitter distribution is the output device, the input unit of analysis intensity is connected to the second information output unit for computing the parameters of the first and second parametric outputs of the unit of analysis intensity are connected respectively with the first and second parametric inputs evaluator distribution, control output unit of analysis intensity is connected to the control input of the computing unit arithmetic mean values.

In the prototype implements the estimation of distribution parameters (intensity - λ_withand the ratio of the information length of the packets and messages ξ) both uniform and h is homogeneous (mixed) flow MEAs - streams, periodically changing its intensity during the operation of TCS integration services, thereby the extension of field of use of the device.

However, the prototype has the disadvantage of relatively low reliability assessment in conditions inherent in the real process of functioning TKS integration services - in conditions of ambiguity (fuzziness) of the parameters of the circulating flow of a multipackage messages. This device allows high accuracy to estimate the parameters of the distribution of only those homogeneous and heterogeneous (mixed) flow map, source characteristics of the packets (the beginning and end of the data portion of the packets defined quantitatively identified clearly and unambiguously, while the signs of the beginning and end of the data portion of the packet IPU for a large number of high-speed flows of messages that are actually circulating in the computer and other telecommunication networks can be identified only qualitatively ambiguous, vague, involving linguistic variable.

Under "features" packages message flow refers to the established and traditional for a specific Protocol in TCS integrated service attributes of the packet header is the number of bits flag the beginning and end of the data portion of the packet, on prednosti and intensity of their sequence within the header.

Analysis of the works [1-6] and the results of studies of the real message flows [7-9] show that the input packet stream IPU users in the existing TCS integration services, characterized by both quantitative and qualitative traits. Its inherent unreliability, fuzzy (vague) a priori uncertainty, causing a lack of clear boundaries of the signs of the beginning of the data portion of the packet and the end of the data portion of the packet. This is especially true for SMEs, when heterogeneous group stream is transmitted over a network such class at a high speed. In these conditions it is quite difficult clearly (clearly) to identify the affiliation of key attributes, such as intensity of the occurrence of the flag the start of the service - indication header of the packet, the number of bits of the symbols of the beginning and end of the data portion of the packet to the feature space.

In the analysis parameters λ_withand ξ, the evaluation of the distribution of message flows, all distinct and clearly identifiable signs of packets can be clearly recorded and numerically described using quantitative measures, while ambiguous identifiable signs require, in order to avoid errors of assessment, verification, additional validation, which is possible on the establishments the m level. This involves verification of ambiguous (unclear) of the identifiable characteristics of the packets, based on the mathematical apparatus of theory of fuzzy sets, involving the identification of criteria for verification of the characteristics of the packets, formulated in the form of a linguistic variable type: "sign clearly does not belong to the space of signs" - "very weak degree set this attribute to space the signs" - "weak degree of belonging to the space of signs" - "belonging and not belonging to the space of characteristics ravnovesnoy" - "a high degree of belonging to the space of signs" - "very high degree of belonging to the feature space" - "the sign of the package explicitly belongs to the space of signs and other Mathematical analogue of such linguistic variables is the membership function of fuzzy sets that are written asand having the physical meaning of the degree (level) confidence in the membership of the sign to the feature space. However, the source data with a vaguely identifiable characteristics used for evaluation of the law of distribution of messages according to the authors of papers [1-6], is 40...50% of the total list of all source data necessary for the implementation of assessment R the material flows with a high degree of certainty. In other words, not taking into account parameters of the stream of packets not clearly identifiable, facilitates the assessment, however, dramatically reduces the confidence level of the results and, consequently, reduces the validity of the decisions on the management of information flows in TCS integration services.

The aim of the invention is a device for the parametric estimation of the distribution of message flows, providing increased reliability assessment in conditions inherent in the real process of functioning TKS integration services - in conditions of ambiguity (fuzziness) of the parameters of the circulating flow of a multipackage messages, devices with high reliability to estimate the parameters of the distribution of homogeneous and heterogeneous (mixed) flow map, identification features packages (signs of the beginning and end of the data portion of packets) can be identified both quantitatively and qualitatively - is ambiguous, vague, involving linguistic variable.

Device for the parametric estimation of the distribution of the message flows is as fo the om. It is known that from the point of view of verification of the observed characteristics of the packets within the estimated message flow, you can view the feature space packages in the form of a set of (transposed vector) [1-6]:

where- transposed vector characterizing (parametrically or vaguely) a feature space packages. The elements of this vector are: ψ - the number of bits flag the beginning (end) of the information part of the packet; β - the sequence in which the following bit flag beginning (end) of the information part of the packet; γ - the intensity of the following bit flag beginning (end) of the information part of the package. It should be noted that each of the communication protocols (TCP/IP, Frame Relay, Token Ring, Fast Ethernet and other)used in TCS integration services, have their own, clearly expressed and described in detail [7-9] signs of packets (the number of bits, the sequence and intensity of the following bit flag beginning (end) of the information part of the package), which allows, ideally, to uniquely identify this package. The problem is that the ideal conditions (no noise, errors, etc. in the functioning of the real TKS integration services, are extremely rare. However, there is a possibility of detection (recognition, detektirovanie the) signs of packages, identifiable both quantitatively and qualitatively (ambiguous, vague, involving linguistic variable). In this case, the expression (1)characterizing fuzzy information (fuzzy knowledge) about the degree of membership of the analyzed characteristic of the package to the feature space of the packet is:

where- transposed vector space is ambiguous (unclear) of the identifiable signs of packets whose elements are obtained with the help of experts in the framework of a simple, hardware-implemented expert systems. This interpretation of the model identify signs of packages allows you to enter the sequential algorithm information not clearly identifiable signs to the mind, causing the possibility of parametric and unambiguous identification of the characteristics of the packets, to improve the reliability of the parametric estimation of the distribution of message flows.

In the framework of the traditional expert system for solving the problem of combining expert opinions, knowledge which is used in the form of pre-formed data on the possible values of the degree of membership of a particular trait packages to the feature space, use one of the standard operations on fuzzy sets - operation disjunctive summation [-6]. In this case, the disjunctive sum, for example, two fuzzy sets (number of experts), is defined in terms of unions and intersections of fuzzy sets as follows:

where- fuzzy set characterizing the opinion of the first (second) expert on the degree of membership of a particular S-th characteristic of the i-th packet in the framework of the j-th message to the feature space;- additions of these fuzzy sets. Received disjunctive sumcharacterizes the joint opinion (in our case two) experts on the values of the fuzzy parameters. For an unambiguous verification of belonging (or not belonging) to a particular fuzzy S-th characteristic of the i-th packet in the framework of the j-th message to the feature space, the joint opinion of the experts analyzed on the basis of the so-called function α-level, which is the criterion unambiguous choice (assignment) quantitative values for the analyzed fuzzy parameters [1, 3, 6]. This α-the level is set in advance as a threshold that defines the uniqueness of a specific characteristic of the package space of the true signs, and many α-level fuzzy membershipcharacterizing question the beliefs of experts, is called a regular set:

The expression (4) is characterized by the fact that if the value of the membership function (certainty) integrated expert opinions for a particular S-th characteristic of the i-th packet in the framework of the j-th message exceeds α-level or equal, this particular trait is true, i.e. unambiguously points to the beginning (end) of the package. It does not matter which of the elements of the vector (2) space is not clearly identifiable signs of packages conventionally understood as the S-th characteristic in the expression (4). This can be either- not clearly identified number of bits of the flag of the beginning (end) of the information part of the i-th packet in the framework of the j-th message, and- not clearly identified the sequence of the following bit flag beginning (end) of the information part of the i-th packet in the framework of the j-th message, or- not clearly identified the intensity of the following bit flag beginning (end) of the information part i-package within the j-th message. Important fact uniquely identify this characteristic to reduce the uncertainty, and therefore, improve the accuracy of recognition of service in the course of further transformation and, ultimately, improve the truth is ity assessment.

With this in mind, is the evaluation of the distribution of the message flows in the claimed device. The analyzed input stream IPU users in the form of a binary pulse sequence, enhanced and normalized by the amplitude and duration of the input amplifier 1 is applied to an information input 81 of the unit of analysis characteristic of the package 8. The unit of analysis of the sign package 8 can be implemented in accordance with the scheme proposed in figure 2. The comparison and decision unit 8 is as follows. Reinforced and normalized by the amplitude and duration of the binary pulse sequence from the information input 81 of the unit of analysis of the sign package 8 simultaneously fed to the inputs 811, 821 and 831 analyzer number of bits of the packet header 8.01, analyzer order bits of the packet header 8.02 and analyzer intensity bit of the packet header 8.03, respectively. The analyzer number of bits of the packet header 8.01 provides a consistent comparison of the number of bits of the received sequence with the reference (accepted for this Protocol, the number of bits of the header) on the basis of ψdescribed in the expression (1). The analyzer sequence of bits of the packet header 8.02 provides a consistent comparison of the sequence of repetition bits of the incoming binary pulse sequence is a reference parameter (characteristic) β described in the expression (1). In the analyzer, the intensity of the bits of the packet header 8.03 sequentially comparing the intensity of the sequence of bits of the incoming binary pulse sequence with a reference on the basis of γdescribed in the expression (1). Thus, in each of the three analyzers (8.01, 8.02 and 8.03) incoming binary pulse sequence is compared by its sign, if the sign of the binary pulse sequence coincided with the reference sign (ψ, β and γ) packet on the appropriate output 812, 822 and 832 of this analyzer to a binary pulse sequence is added to the binary symbol 1 ("unit") in the case of a match, or 0 (zero) in case of discrepancy.

The original binary pulse sequence, but each with its additional binary symbol (1 or 0), the output 812 analyzer number of bits of the packet header 8.01, output 822 analyzer order bits of the packet header 8.02 and output 832 analyzer intensity bit of the packet header 8.03 act respectively on the first indicative 841, the second indicative 842 and the third indicative 843 inputs of the analyzer matches the characteristics 8.04. Analysis (comparison) these additional characters in the analyzer matches the characteristics 8.04 as follows. If the complement is selected characters entered all three "units", this binary code sequence, the characteristics of the packet is recognized as uniquely identified, it is certainly a bit sequence flag the beginning (end) of the information part of the package and, without additional characters through a clear exit 845 analyzer matches the characteristics 8.04 and clearly indicative of the output 84 of the unit of analysis characteristic of the package 8 is supplied to the information input unit 21 of the calculation parameters to further define the current values of flow parameters λ_withand ξ. If additional characters from any of the three analyzers (8.01, 8.02 and 8.03) received at least one "zero", then this is the binary code sequence, the characteristics of the packet is recognized as ambiguous (unclear) identified, is a fuzzy code sequence and require additional verification from the point of view of the answer to the question whether it is the bit sequence flag the beginning (end) of the information part of the package or not. This option, in the worst case (when all three "zero", the mismatching of all three characteristics), can be described by expression (2), or to have one or two characteristics not clearly identifiable or- not clearly identified number of bits of the flag of the beginning (end) of the information h is STI i-th packet in the framework of the j-th message, or- not clearly identified the sequence of the following bit flag beginning (end) of the information part of the i-th packet in the framework of the j-th message, or- not clearly identified the intensity of the following bit flag beginning (end) of the information part i-package within the j-th message, or a combination of both. In this case, the binary code sequence, vaguely the characteristics of the packets (fuzzy code sequence), through the fuzzy output 844 analyzer matches the characteristics 8.04 arrives at the main entrance 851 verifier 8.05 done in shift register 8.05-1, and through fuzzy indicative of the output 82 of the unit of analysis characteristic of the package 8 is fed to the input 91 of block transformations of the form characteristic of the package 9 for more mathematically correct processing and validation uniquely belonging to the reference set of identifying features. Additional binary characters (1 or 0) play the role of a preliminary "tips" for experts that opinion is used when computing the transform block type characteristic of the package 9, which can be technically implemented, as shown in figure 4. Transform (convert) the original data, the characteristics of the package and specified in fuzzy form (fuzzy the annual sequence) to the form suitable for determining the current values of flow parameters λ_withand ξand, ultimately, for accurate parametric estimation of the distribution of message flows, and from the point of view of mathematics, the correct computation of the integrated expert opinion about belonging or not belonging to S-th characteristic of the i-th packet in the framework of the j-th message to the feature space, is carried out in accordance with the expression (3) as follows. Fuzzy code sequence, the characteristics of the packets from the input 91 of block transformations of the form characteristic of the package 9 is fed to the input 911 counter 9.01, which registers and sorts information into two parts, in accordance with the opinions of experts (number of experts) about the degree of membership of a particular S-th characteristic of the i-th packet in the framework of the j-messages to the feature space. First 912 and the second 913 outputs of the counter 9.01 correspond to the data from the first and second experts, with these outputs information in binary code is supplied respectively to the input 931 main storage element 9.03 and direct entry 941 auxiliary storage element 9.04, and respectively on the first 921 922 and the second input of the transmitter additions 9.02. The transmitter additions 9.02 realizes the function of the arithmetic subtraction of unit values f is NCCI facilities fuzzy sets, in accordance with the algorithm described in [1, 2], for example, if

whereand- additions of fuzzy setsandformulated by experts and about the degree of membership values (membership function) of a particular S-th characteristic of the i-th packet in the framework of the j-th message to the feature space. The main 9.03 and auxiliary 9.04 storage elements store fuzzy information from an expert and through its outputs 932 and 942 in binary code given values of membership functions of fuzzy sets on the main entrance 951 main evaluator crossing 9.05 and at the main entrance 961 auxiliary transmitter crossing 9.06, respectively. Each of the main 9.05 and auxiliary 9.06 calculators crossing, getting in binary code on their additional inputs 952 and 962, respectively, the values of the elements of the complement of fuzzy sets with the first 923 and the second 924 outputs transmitter additions 9.02, performs the function of the intersection, as described in [1, 2, 6]: the primary evaluator crossing 9.05 performs an operationwhile the auxiliary transmitter crossing 9.06 performs an operation . Output 953 main evaluator crossing 9.05 and exit 963 auxiliary transmitter crossing 9.06 obtained values in the binary code are received respectively in the first 971 and the second 972 inputs evaluator Association 9.07 performing the final cycle disjunctive summation in accordance with the expression (3). Output 973 evaluator Association 9.07 received totals (common expert opinion on value)the membership functions of the S-th characteristic of the i-th packet in the framework of the j-th message to the feature space in the binary code is fed to the input 981 analyzer functions α-level 9.08, auxiliary input 925 evaluator additions 9.02 and auxiliary input 943 auxiliary storage element 9.04. The analyzer features α-level 9.08 provides unequivocal choice (assignment) quantitative values of the analyzed fuzzy flow parameters (signs of packets) [1, 3, 6] in accordance with the expression (4). As, in fact, a programmable comparison circuit, which compares the binary code values with a predefined (programmed) αand received from the evaluator Association 9.07 verified the values of the membership function of a particular S-th characteristic of the i-th packet in the framework of the j-messages to the feature space, the analyzer function is α -level 9.08, by comparing the threshold (α-level) unequivocally determines whether the characteristics of the package to the space of the true signs. If the value of the membership function (certainty) integrated expert opinionobtained from the output of the transmitter associations 9.07-specific S-th characteristic of the i-th packet in the framework of the j-th message exceeds α-level or equal, this particular trait is true, i.e. that uniquely specifies the flag to the beginning (end) of the information part of the package and the analyzer functions α-level 9.08 outputs 982 binary value 1 is "unit". If α-the level exceeds the value of membership function (certainty) integrated expert opinion obtained from the output of the transmitter associations 9.07 analyzer functions α-level 9.08 outputs 982 binary value 0 is zero. Information is transmitted to the auxiliary input 925 evaluator additions 9.02 and auxiliary input 943 auxiliary storage element 9.04 is intended for the case when the number of experts more than two. In this case, is determined by addition of the received output 973 evaluator Association 9.07 fuzzy sets in computer additions 9.02 and obtained from the output 973 evaluator Association 9.07 testing the value is overwritten in the auxiliary storage element 9.04, playing the role information from the first expert. Information from the new (e.g., third) expert is recorded by a counter 9.01 in the main storage element 9.03 and compute cycle repeats again. Output 982 analyzer functions α-level 9.08 obtained quantitative values (the signal "zero" or "unit") in binary code through the output 92 of block transformations of the form characteristic of the package 9 is coming to return the indicative input 83 of the unit of analysis characteristic of the package 8, as for the verifier 8.05, in fact, a command that indicates that either the sign package is recognized as true (signal 1 - "unit"), the packet header verified and can be directed as in the computing unit 2 parameters to further decrypt or sign the packet is not recognized as true (signal 0 - zero), it is not the packet header (as, for example, similar to the header on the structure of the information component of the package information error).

The verifier 8.05 unit of analysis of the sign package 8 can be implemented in accordance with the scheme proposed in figure 3. The verifier 8.05 implementation adopted in the processing block type characteristic of the package 9 decisions about belonging (or not belonging) and analyzed mathematically transformed trait package to the feature space and the transmission of information in the block is ycycline 2 parameters as follows. In the shift register 8.05-1 verifier 8.05 already stored previously received from the analyzer matches the characteristics 8.04 unit of analysis characteristic of the package 8 and recorded through the main entrance 851 verifier 8.05 and the main entrance 8051 shift register 8.05-1, the binary code sequence, vaguely the characteristics of the packets (fuzzy code sequence). From the output of the transform block type characteristic of the package 9 through the return indicative of the input 83 of the unit of analysis of the sign package 8 to the input of the controller 8.05-2 verifier 8.05 come in binary code, the quantitative values (the signal "zero" or "unit"). If the received signal 1 ("unit") - feature package is recognized as true, the packet header verified and can be directed as in the computing unit 2 parameters for further processing. In this case, the controller 8.05-2 verifier 8.05 generates a binary pulse signal 1 ("unit"), which is output from the controller 8.05-2 is supplied to an additional input 8052 shift register 8.05-1. Upon receipt of this signal, the shift register 8.05-1 verifier 8.05 function inversion does not. After removing the additional binary characters (1 or 0), it reads and transmits from its output stored, already considered verified unambiguously identified on the basis of the package is considered to be the true sequence of bits flag the beginning (end) of the information part of the package through a clear indicative of the output 84 of the unit of analysis of the sign package 8 on the information input unit 21 parameter calculation 2 to further determine the current values of flow parameters λ_withand ξ.

If the input controller 8.05-2 verifier 8.05 of the block 9 has received the signal 0 ("zero") is a sign of the package is not recognized as true, it is "not a header, the packet header verified as error, the controller 8.05-2 verifier 8.05 generates a binary pulse signal of 0 (zero), which is output from the controller 8.05-2 is supplied to an additional input 8052 shift register 8.05-1. In this case, after removing the additional binary characters (1 or 0), the shift register 8.05-1 verifier 8.05 through a clear indicative of the output 84 of the unit of analysis characteristic of the package 8, transmits the binary code of the analyzed bit sequence on the information input 21 of the computing unit 2 parameters, but, in order to prevent false positives decoder packet headers 2.01, detector pauses 2.02 and counter information length of a multipackage messages 2.03 block parameter calculation 2, invert the first bit of the identified as "not the header bit sequence on the opposite ("null" to "unit" or Vice versa). Since this is obviously an informational error caused by distortion of the channel, noise, etc., this procedure on the content part of the package, it will not affect, whereas will eliminate needn the atomicity (blurring) for subsequent procedures parametric estimation of the distribution of message flows, pre preventing false operation of the decoder packet headers 2.01, detector pauses 2.02 and counter information length of a multipackage messages 2.03 block parameter calculation 2.

Thus, based on the mathematical apparatus of theory of fuzzy sets, involving the identification of criteria for verification of the characteristics of the packets, formulated and used by experts in the form of a linguistic variable, by mathematically correct calculation unit analysis of the sign of the package 8 and the power transformations of the form characteristic of the package 9, managed to achieve that with a clear indicative of the output 84 of the unit of analysis of the sign package 8 on the information input unit 21 parameter calculation 2 always, despite often present in real communication channels (on the background noise and error), ambiguity (fuzziness) identification of signs of packets arrives verified binary pulse the sequence in which parametrically and unambiguously defined signs of packages multipackage messages.

Further stages parametric estimation of the distribution of message flows are implemented as follows. The analyzed input stream IPU - verified binary pulse sequence in which parametrically and unambiguously defined characteristics acetamnophen message arrives with a clear indicative of the output 84 of the unit of analysis of the sign package 8 on the information input unit 21 parameter calculation 2, where is the determination of current values of parameters λ_cand ξ. The computing unit 2 parameters can be implemented in accordance with the scheme proposed in figure 5. The calculation in block 2 current settings λ_withand ξ, as follows. The decoder 2.01 analyses input block parameter calculation 2 verified binary pulse sequence, and finds in it the identified symptom information part package runs counter 2.03, moments of complete accounts are determined by the moments of detection decoder identified sign of the end of the data portion of the packet. Moments of receiving the values of the information length message m_cin the transmitter of the information ratios of the lengths of 2.05 and the reset of the counter 2.03 determined by the moments of appearance of pulses at the output of the detector pauses 2.02, the locking completion message. In the transmitter of the information ratios of the lengths of the packets and messages 2.05 values ξ=m_p/m_withfor fixed length packets received for this Protocol in TCS integration services and set by the control unit 6, the flow through the control input 23 of the block 2 to the second control input 252 of the transmitter of the information ratios of the lengths of the pack is impressive and messages 2.05 pulses, the number of which corresponds to a value of m_c. The intensity value λ is determined by the counter 2.04 on pulses from the output of the detector pauses 2.02 for the time interval defined by the control block 6, by applying pulses with a frequency f_nebthrough Abdoulaye entrance 22 of block 2 on the second Abdoulaye input 242 counter 2.04.

Values ξ and λ in parallel code act accordingly with the information of the outputs 24 and 25 of the computing unit 2 parameters for informational inputs 31 and 32 of the unit for computing the average values of 3. The power calculation of arithmetic mean values of 3 can be implemented according to the scheme shown in Fig.6. In the case when there is a homogeneous (non-mixed) flow MEAs users TCS, when the sources emit messages at regular intervals, the calculation of the numerical values averaged over the observation interval of flow parametersoccurs as follows. Parameter values ξ binary sequence received at the first input 31 of the block 3, and then to the input of counter-divider values duration 3.01 producing an arithmetic operation of summing successively incoming values ξ and dividing the sum by the number of samples. At the output of the counter-divider values duration 3.01 and on the ground in orationem the output 33 of the block of calculation of arithmetic mean values of 3 in parallel binary code get the value of the parameter averaged over the observation interval. Parameter values λ binary sequence received at the second information input 32 of the block 3, and then to the input of counter-divider intensity values 3.02 producing an arithmetic operation of summing successively incoming values λ and dividing the sum by the number of samples. At the output of the counter-divider intensity values 3.02 and permissive input element PROHIBITION 3.03 in parallel binary code have a value foraveraged over the observation interval. The second information output 34 of the block 3 with the output element PROHIBITION 3.03adjudged only if at the moment on the control input 35 of the block 3 and for prohibiting the input element PROHIBITION 3.03 not submitted in parallel binary code signal from the control output 72 unit rate analysis 7. Otherwise, the second information output 34 of the block 3 with the output element PROHIBITION 3.03 valuenot served. The observation interval to calculate the parametersandis set by the control unit 6 depending on the required accuracy.

The control unit 6 may be implemented according to the scheme proposed by figan control pulse sequences is carried out by setting the elements of the group divider with variable division factor (DPCD) the corresponding ratios of the pulse sequence, coming from the generator output 6.01. Installing coefficient element 6.03 is determined by the value of t_neb=1/f_nebby setting the ratio of the element 6.04 determined by length of service adopted for this Protocol is currently working with TCS integration services (m_p)sets the ratio of the element 6.02 determined necessary to calculate the number of packets (k).

When the first 33 and second 34 information output unit 3 are simultaneously the values of the parametersandaccordingly, the value ofwith the first data output 33 unit 3 is input to the block type definition of the distribution of 4, which is compared with a single threshold. The block type definition of the distribution 4 can be implemented according to the scheme proposed in Fig.7. Determine the type of flow distribution IPU as follows. coming from the output of block 3 in parallel binary code in the DAC 4.01 is converted into an analog voltage, which Comparators 4.02, 4.03 compared with the threshold voltage produced by the generator threshold voltage 4.04. The value of the threshold voltage corresponds to a single. The output 42 comparator a signal of logical units in excess of the value of a single value and is supplied to the second modification of the input 54 of the transmitter distribution 5, in the opposite case, the emergence of logical units occurs at the output of comparator 41 4.03 and is supplied to the first modification of the input 53 of the transmitter distribution 5. When there are logical zeros on the outputs of the Comparators 4.02 and 4.03 decides thatthis is evidenced by the presence of a logical unit at the output 43 of the element OR NOT 4.05 and receipt of this logical unit to the third modification of the input 55 of the block 5. Thus, by comparing the results, by applying a control pulse to one of the three modification inputs 53-55 evaluator distribution 5, the decision on the calculation of one of the three well-known and described in the prototype (see RF patent №2165100, 7 G 06 F 17/18, 2001, bul, equations (1-3)) analytical expressions for probability density for values of parametersandcoming from the first 33 and second 34 information output unit 3 of the first 51 and second 52 informational inputs evaluator distribution 5. Calculations can be performed for different values of the number of packets (k), the choice of values is performed by the control unit 6 by submission on the clock input 56 of the block 5 and to the first input 510 ele the enta And 5.02 pulses, the number of which corresponds to the specified number of packets. Admission to the second input 511 item And 5.02 of pulses from the first information input 51 unit 5 provides the appearance of the output element And 5.02 of the control signal, the number of pulses which corresponds to the specified number of packets. This signal, when the clock input 506 arithmetical-logical item 5.01, initiated the beginning of the calculation procedures. The calculated values of the uniform distribution of flow MEAs output 59 calculator distributions 5 are served in parallel binary code on the recording device.

In the case when there is a heterogeneous (mixed) flow MEAs users TKS integration services when the sources of mixed type display messages irregularly - single ISP or packs COI with lengths distributed according to a geometric law, the calculation of the numerical values averaged over the observation interval parameter flow (occurs as described above, and the calculation of the numerical values of the parameter λintensity of flow, as follows. Parameter values λ binary sequence received at the second information input 32 unit 3 for calculating averaged over the observation interval parameter flow ( ) and to the input 71 of the unit of analysis of intensity 7. Parameter values λ received in parallel on the information input 701 element of comparison 7.01 unit 7, to the input of memory element 7.02 unit 7 and on the information input 706 of the secondary element And 7.04 unit 7. Online storage element 7.02 stores the value of parameter λ in the previous step value of λ₁. With the auxiliary output 707 memory element 7.02 value λ₁arrives at the auxiliary input element 702 comparison 7.01, which compares the value of the previous reference parameter (λ₁with a value of the subsequent reference (λ₂) is received by the information input 701 element of comparison 7.01. The comparison is made according to two criteria: λ₁≠λ₂and λ₁=λ₂. If the values of the counts is equal to (λ₁=λ₂), this confirms that at the input device, we have a uniform (non-mixed) flow map, and therefore the comparison element 7.01 does not generate a signal on the control output 72 unit 7 and the signal inputs of elements And 7.03 and 7.04. This means that the control input 35 of the block 3 and for prohibiting the input element PROHIBITION 3.03 unit 3 from the output 72 of the block 7, the signal is not received, therefore, the output element PROHIBITION 3.03 and the second information output block 34 is 3 in binary parallel code have a value for and further calculation of the parameters of the distribution of the message flows is as described above.

If the counts are not equal (λ₁≠λ₂), this confirms that at the input device, we have a heterogeneous (mixed) flow map, and therefore the comparison element 7.01 outputs a signal on the control output 72 unit 7 and the signal inputs of elements And 7.03 and 7.04. The signal from the control output 72 unit 7 is supplied to the control input 35 of the block 3 and for prohibiting the input element PROHIBITION 3.03, locking him out and not allowing you to giveon the second information input 52 of the block 5. From the information output 708 memory element 7.02 parameter value λ₁is supplied to the information input 704 of the primary element And 7.03, and online storage element 7.02 records the value of the new parameter. On the information input 706 of the secondary element And 7.04 have a value of λ₂. The output of the comparison element 7.01, acting on the signal inputs 703 and 705 of the primary and secondary elements And (7.03 and 7.04, respectively, opens the device, allowing you to get on their outputs, and means on the first 73 and second 74 parametric output unit 7 parameter value λ₁and λ₂respectively. Parameter values λ₁and λ come to the first 57 and second 58 parametric inputs evaluator distribution 5, and then on the first 507 508 and the second parametric inputs arithmetical-logical item 5.01, which calculates the values of the distribution in accordance with the analytical expression to determine the convolution of the corresponding probabilities (see RF patent №2165100, 7 G 06 F 17/18, 2001, bul, the expression (4)), and the presence of a control pulse on any of the three modification inputs 53-55 evaluator distribution 5 in this case does not play a role. The calculated values of the distribution is heterogeneous (mixed) flow MEAs output 59 calculator distributions 5 are served in parallel binary code on the recording device.

In the end, the output of block 5 are written in binary code, credible and verified using the mathematical apparatus of theory of fuzzy sets the value of a distribution of either homogeneous or heterogeneous (mixed) flow map, depending on the characteristics of the graph TKS integration services.

Thus, the analysis of the principle of operation of the inventive device for the parametric estimation of the distribution of message flows shows the obvious fact that along with saved possibilities of estimating the distribution parameters of a heterogeneous (mixed) flow MEAs - threads periodically enaudi its intensity during the network operation, the device can improve the accuracy of estimation of distribution parameters message flows, identification features packages (signs of the beginning and end of the data portion of packets) can be identified both quantitatively and qualitatively - is ambiguous, vague, involving linguistic variable.

This device provides increased reliability assessment in conditions inherent in the real process of functioning TKS integration services - in conditions of ambiguity (fuzziness) of the parameters of the circulating flow of a multipackage messages, due to the volatility (uncertainty, variability) of the conditions of functioning of a network, which significantly extends the application of the device, extends the functionality of the equipment, where the claimed device for the parametric estimation of the distribution of the message flows will be used.
