The technical field to which the invention relates.

The present invention relates to the identification of solutions for connectivity of network elements using the functions of a network management system, which provides control elements in a data network.

The level of technology

Modern data networks contain a large number of network nodes (network elements), and a large number of nodes contain switching elements, such as cross-connectors containing a complex system of input and output ports. Each input and output port typically contains many compounds and is characterized by different features. For example, some output ports can be used to reset the part of the signal, while the other output ports provide end-to-end transmission of the input signal. Switching elements not only contain different types of ports and connections, but usually have certain limitations on the equipment so that not every input connector can work with arbitrary output connector within the same or different switching network elements. Such restrictions may be many reasons for this, including differences protocols, physical characteristics, incompatible location in space, preferred is or non-preferred connections, limitations related to cost, etc.

For solving different problems associated with finding suitable compounds in modern networks typically create and use the following hierarchy of control systems:

system (SSAS (NMS) network management network, and the CEL keeps track of all network elements, that is, contains information about the types of all existing network nodes and their connections at any current moment,

system (TMN (EMS) management element of a particular network element TMN allows you to monitor one element, that is, contains information about the different types of compounds that contains a network element (node), and the various limitations of the equipment of such a network element.

SSA considers the network as the current configuration of the network nodes and can communicate with any node by contact with his TMN.

When you want to find the route between two points in the network, SSA uses a program, usually called the determinant of the route intended to determine such a route is available between network elements. After you've found the preliminary route, which, for example, is defined as the shortest route, it is necessary to determine the detailed configuration of connectivity through the elements planned for use in the route. With this purpose, piss on the rotatin to TMN each node in the route to search for specific solutions for connectivity.

A similar method is described in the publication EP 1130942 A2, in which the network administrator requests the resource management mechanism for the selection of the output port to the input port of the optical switching device packages. The mechanism of resource management then accesses a database that contains the settings of the access port of the switching element, and after reserving a free output port includes an optical mechanism control switch.

Consistent, repetitive stages of interaction between SSA and each of the TMN take considerable time, require multiple exchange protocols. Sometimes the decision on the possibility of providing connections to a given host cannot be found because of any limitations on equipment, unknown to piss, and then a substantial part of the route determination process must be repeated, that is, the number of search operations performed by SSA in a sequential, repetitive interaction with the TMN increases. As a result, the process requires more time and is inefficient.

The invention

Thus, the present invention is directed to such a method of finding solutions to possible connections in a network containing a large number of switching network elements and the SU, which allows you to efficiently search at the level of piss.

Brief description of the invention

To reduce the time required to search for possible connections in a network element, SSA (network management system) may include a centralized database or table connectivity based database connectivity component of many network elements. Each database connectivity components can be copied from the TMN system (control element) of the corresponding network element. In this case, the CEL will just "know" the structure of each network element.

In this application the term SSA should be understood as a control object that provides control over a particular group of network elements forming the network or part of it.

In other words, the purpose of the present invention can be achieved by using method of finding solutions for the possibilities of connections for network elements that must be included with the formation of the route that is selected in the network managed by the system (CCS) network management, in which each network element includes input ports and output ports, and each port provides multiple connection points, the method includes providing at the level of the SSA table (TS (ST) in which zmozhnostej connection contains information about possible internal connections between the points of connection between any input port and the connection points of any output port in any network element that is managed specified SSA, always, when a particular network element with its input port and its output port intend to use in the route, provide solutions for connectivity specified network element-level SSA.

The method also includes continuous updating SSA using the TMN corresponding managed network elements in any changes to the table connectivity component, for example, in relation to the availability of specific points of the connection.

However, to reduce the amount of memory required to record such table in SSA, the purpose of the present invention can be achieved without information from SSA of each individual network element by performing the following steps:

- classification of join points as input ports and output ports of all network elements in the form of a set of groups of compounds, denoted by 1, 2, 3... n, in which each group has similar properties and/or constraints

- assign each input port and each output port of a specific network element one or several the x of the above groups of compounds,

- creation of the table of connectivity for submission to the General rules for connectivity, indicating the formation of connections between any arbitrary group of compounds of groups 1, 2, 3... n, belonging to the input port of the network element, and any arbitrary group of compounds of groups 1, 2, 3... n, belonging to the output port of the network element, always selecting for use on the route of a specific network element from its input port and its output port is provided by the possibility of obtaining solutions for connectivity for the specified specific network element-level SSA by applying the rules of connectivity to groups of compounds assigned to the selected input and output ports.

Needless to say that the above method is universal for all network elements managed by the SSA.

In accordance with a preferred version of the method it contains a layout table (TC) connectivity that the rows of the table represent groups 1, 2... n connections of the input ports, table columns represent groups 1, 2... n connections output ports, and each cell is the intersection between a particular row and a particular column contains information about the educational opportunities internal connection is between the connection point, owned by the specified particular group of input ports, and the connection point belonging to the specified group-specific output ports.

It should be emphasized that in the preferred embodiment of the present invention SSA does not need to know (to contain) the structure of the connectivity of each network element (SE (NE). Instead, it contains one relatively small table (TC) connectivity, which is built to reflect the General rules of connectivity of network elements and, thus, effectively helps to identify workable solutions for connectivity. In SSA can be recorded some additional information, which will be described below.

In accordance with additional, more nuanced version of the method, it contains:

- an appeal to the SSA by specifying a specific network element from its input port and its output port is required for the selected route, to obtain solutions for connectivity for the specified network element,

- check in SSA, which of the groups of compounds of the above groups 1, 2... n is present in the specified input port and which is in the specified output port,

- application of the rules of connectivity by using the specified table (TC) connectivity in SSA for the distribution, can be made the desired connection between the at least one group of the groups of compounds of the input port and at least one group of the groups of compounds of the output port;

- in case of approval, accounting solutions-defined connectivity, and

conversion from SSA to the system management network (TMN) of a particular network element to activate specific internal connection element

- in case of negative result of a decision of transfer to the SSA reports that the decision on the possible connection not defined for the specified the specified input port and the output port of a solar cell.

The choice of the SE with its ports for a route can be performed, for example, using the Pathfinder definition of the route, part of the SSA. If connectivity is not found for the AOC selected by the Pathfinder program, it must be properly informed about this.

The above variant of the method demonstrates that the network element is performed only work at a lower level (activation of internal connections) and with virtually no consistent repetitive stages of interaction to search for solutions from item-level (TMN) to SSA. Thus, if the spiral is a great solution for connectivity between the input port and output port of a specific network element (SE) were taken at the level of the AOC would require multiple communication iterative solver between TMN and piss.

The task of finding solutions for connectivity to network elements can be almost completely solved at the level of the SSA, so that the level of the TMN leave only the activation of internal connections, in view of the fact that at the level of the SSA already has all of the information related to the groups of compounds associated with each port in each AOC, and all information on possible options for connections between any of the "input" connection groups and any "output" connection groups.

The method, in particular the stage of application of the rules on connectivity, may further comprise a step guidance on the level of internal SSA connections between the contact point of the input group of compounds, and the contact point of the output group of compounds in which the specified input connection group and the specified output group of compounds is chosen at the level of the SSA for a specific network element as a solution for connectivity.

Search solutions for connectivity (either using TS, compiled from the tables of the connectivity component, or using the vehicle of the General rules for connectivity) can be completed by checking the information about sonatacontinue. In particular, it can be executed by the provisional view in the SSA database of active compounds and subsequent references to it (or so-called hashed tables XT (HT), which shows the internal connections of the network elements involved in a given time. XT consists of a set of hashed subdatasheets assigned to the corresponding network elements. Each heshirovanie the subtable contains only the list of employed internal connection element, and therefore is economical from the point of view of memory space, since there is no need to record the status of all possible real-world connections that can be established in the AOC between all its input and output connection points.

When using the TC of the General rules of connectivity stage of verification employed compounds may contain preliminary presentation and subsequent access to the database, intended for reception of the plurality of existing connection points in each group of compounds of specific item; when this instruction is executed after comparing the information about the existing connection points in the selected input and output connection groups with information about the involved joints.

For a more detailed explanation of the method should be given some information which I am about organization of SSA. From a query that specifies a particular network element, SSA receives the designation of input and output ports of the element. To this end, any SSA contains its topological information, preferably in the form of a network graph. As mentioned above, the SSA contains a table (TC) connectivity, allowing you to make decisions about the possibility of creating an internal connection between the selected ports. Table (TC) connectivity can be built according to the table connectivity component of the managed network elements. In this case, the vehicle "knows" all limit points of connectivity of these network elements and allows us to find solutions for connectivity at the level of piss.

In accordance with the preferred implementation of the present invention the group of compounds present on certain ports, for any of the network elements managed by the SSA, additionally described using topological information. If necessary topological information may include registration of existing connection points in each group of compounds of any port of the managed network element. Although this information is quite detailed, it is not complete information about the internal structure of a network element, as is some of the solutions of the prior art. Table connectivity (TC) SSA reflects the General rule of connectivity, allowing you to decide whether or selected ports (on the basis of the groups of compounds that they contain) the ability to create internal connection between them. In fact, this table connectivity considers and consolidates all limit points of connectivity, known to the managed network elements.

Based on the above and in accordance with another aspect of the present invention proposed an improved system (CCS) network management containing block (MC (SN) of the pointing device connectivity, providing the opportunity to identify at the level of the SSA solutions for connectivity to a specific network element that must be included in the route that is selected in the network managed SSA, in which the pointing device connectivity contains a table (TC) connectivity, which contains data about possible internal connections within any of the network elements managed by the specified SSA.

In one embodiment of the invention, the CU consists of database connectivity derived from the TMN relevant network elements.

In accordance with the preferred implementation of this SSA system sod is RIT:

modified topological data related to the network elements specified network and their ports, each input port and each output port of any network element respectively assigned to one or more groups 1, 2,... n connections for connection points so that each group of compounds characterized by similar properties and/or constraints, and

TC contains:

- General rules of connectivity, indicating the formation of connections between any arbitrary group of compounds of groups 1, 2, 3... n, belonging to the input port of the network element, and any arbitrary group of compounds of groups 1, 2, 3... n that belongs to the output port of the network element, while TC, thus, provides the possibility of defining in SSA, is there a solution for connectivity in the specified network element, upon receiving a request that indicates a particular network element with a pair of input and output ports that are required for use in the selected route.

Table (TC) connectivity, preferably, is constructed so that the rows of the table represent groups 1, 2,... n compounds belonging to the input ports, and the columns of the table represent groups 1, 2,... n compounds belonging to the output ports, and each cell is the intersection of exactly what row and a particular column contains information related to educational opportunities, the internal connection between the at least one connection point from the group of compounds belonging to the input port of the network element, and at least one connection point from the group of compounds belonging to the output port of the specified network element.

If necessary, the pointing device connectivity in SSA may contain a database of active compounds (so-called hashed table) in the form of an information chain, each of which denotes the internal connections that are currently employed in a particular network element. Each chain is intended for one of the employed compounds in which the chain belonging to one network element, the hashed form a subtable of this element.

When TC is built for groups of contact points, the modified topological data can, if necessary, contain a database for registering a set of existing connection points in each group of connections for each port of each element. To specify a valid connection TC should enable comparison of information about existing connection points in the selected input and output connection groups with information about the involved joints.

ACC is accordance with the third aspect of the present invention also offer a computer software product, which can be directly loaded in the internal storage device of a digital computer, containing parts of software code designed to perform steps of the method described above, when the specified product runs on a computer.

A computer program product, recorded on the recording media used with your computer contains a software tool which is read by the computer, ensure the implementation of computer management functions network management system, as described above.

Detailed description of the invention

1 shows a known type of interaction between SSA and the TMN to determine solutions for connectivity in the network element, selected to form part of the route in the network (not shown). SSA (network management system) is indicated by the number 10, includes a program to identify the route (indicated by the number 12) and data about the network topology (number 14), which is usually built in the form of a graph showing the existing network elements, ports and layout of elements in the network. Function definition of the route is in the routing network in accordance with a variety of conditions and on the basis of the network topology, and for forming in the WMS request, with specific network elements and their ports (that is the selected input port and a selected output port). Information about the selected ports then passed from SSA in the TMN (system management setevie elements) of each item selected for a route (blocks TMN: 1, i... n indicates the number of 16 links). TMN specific network element searches the internal connection between the selected input then the om and the selected output port, using the information 18, available at ports and based on specific constraints, known TMN. Restrictions can be the following: the selected ports may be available or not, the point of connection to the selected ports may be available or not available for some of the connection points may be prohibited for the desired connection type, etc. Restrictions and physical accessibility of the compounds can be reflected in the so-called availability data port associated with a specific port, and in the TMN has a same number of data (databases), as the number of ports in the item. After clarification of all issues related to the availability of relevant TMN form report to SSA, whether the solution found by connectivity. The interaction between SSA and the TMN may include many steps, and therefore takes considerable time. The process of determining the route is long and complicated; when in the process formed a pause request to the TMN, such interruptions/interactions take considerable time.

Figure 2 shows a diagram reflecting the interaction between the modified SSA and many TMN in accordance with one embodiment of the proposed invention. Modified SSA contains manipulator (MS) connectivity with t is blica (TC) connectivity, which, in General, may consist of tables of connectivity of all relevant TMN for making decisions on connectivity at the level of the SSA. This can be ensured by a dynamic update of the pointing device connectivity restrictions of elements, for example, to change the status of ports or connection points, as indicated by the dashed lines.

Preferably, all the connection points existing in the ports of network elements (see also figure 3), managed SSA, are classified into the group of compounds. Each group is characterized by certain properties and limitations. Due to this huge number of points of connection of all network elements are divided into a relatively small number of groups, and each of them has a known behavior. SSA 20 (see figure 2) contains the keys 22 of the route, the modified data 24 topology, which additionally contain information about specific groups of compounds, existing (or assigned) to each port of the network elements.

Modified SSA additionally contains a new block 26 manipulator (MS) connectivity, which contains a table (TC) 28 connectivity. One preferred example of the table connectivity as shown below in figure 4. Table 28 connectivity in dei is titelliste contains the so-called General rules of connectivity, which formulate (at the level of the SSA), can be, and how the ports selected by the vascular route, mutually connected, impose conditions of compatibility/incompatibility between groups of compounds of input and output ports. Because the group of compounds connection points formed on the entire network, these compatibility conditions applicable to any network element having ports containing any of these groups.

Table TC (28) connectivity unit (26) MS after receiving information about groups of compounds existing in the selected ports of the element that is specified for the route, allows you to generate answers for possible connections. This information may be transferred to the appropriate TMN 32 to select the real inner connection and activate it. However, to minimize the likelihood that the desired connection is employed, SSA may apply to the level of the TMN only after exchanging information with the additional block 30 of the manipulator 26 connectivity. This unit is called a hashed table (XT), which recorded only occupied connect each network element; it is constantly updated TMN 1,... m. When possible connection permitted vehicle and checked XT, the internal connection may be actually specified and transmitted to activate the appropriate TMN 32.

On IG depicts the network element 40, having multiple input ports 42 (1,... K) and the number of output ports 44 (1,... F). Each of the ports contains the join points are represented as circles and indicated by the number 46. All the connection points existing in the network elements managed by the SSA, in accordance with the present invention, schematically divided into a number of groups 1, 2... n compounds. Each group has its specific limitations and behavior (properties, features) connection points.

For example, the point of connection of a particular group, located in the input ports can be connected only with the points of connection of the same group located in the output ports. In one case, the point of connection of the input port can be used to log into the network element, such as a cross join, virtual containers carrying data in accordance with the hierarchy of data transmission SDH/SONET (SDH - Synchronous Data Hierarchy the European standard for the use of optical cables as a physical transmission medium for high-speed transmission networks at a considerable distance, SONET - Synchronous Optical Network standard that defines the speed signals and interfaces for synchronous optical network, providing data transfer speeds of more than one Gigabit per second). In this case, the connection point may be referred to as point VC (VC) (virtual the aqueous channel). In the switching equipment SDH points VK are usually for input/output data streams in accordance with the standard VC-4.

Each port contains a point 46 of the connection belonging to one or more groups 48. For example, input port 1 (indicated by the number 50) contains a point 46 compounds belonging to three groups of 48 compounds, namely groups 1, 2 and 5 connections. Each of the connection points within one group has a sequence number or other identifiers.

Figure 4 presents an example of the preferred option implementation table (TC) 52 connectivity, which contains n columns 54 and n rows 56, where each row is allocated to a particular group of compounds, or input ports, or simply groups of input connections, and each column is assigned a specific "output group"connections. The characters in the intersection of a particular column and a particular row have the value that the internal connection between a particular input group of compounds and specific output group of compounds is impossible or possible in the presence or absence of certain conditions.

Figure 5 presents the portion of the database employed compounds or so-called heshirovanie the subdatasheet 58 for a specific network element. The table does not have any standardized volume and contains the only chain 60, which contain information about currently the connections in the network elements. The table is used as follows: after defining the possible connections between, say, the input group 1 compounds and output group 2 compounds, SSA checks the hashed subtable item of interest, to specify a specific connection points for the TMN. Since points 4 and 1 connection input group 1 compounds are already occupied, they will not be specified in the order. In addition, there can be mentioned the connection point 5 output group 2 compounds. In addition, it is assumed that the selected groups of the respective input and output ports of the desired item, there are other points of connection, and they will be approved by the TMN. However, the table will be useless, if not will be provided with an additional connection point in the relevant groups in addition to those already occupied. In this case, from the TMN will receive a negative response, in this special case, between SSA and the TMN will occur consistent repetitive interaction. To avoid this situation, the modified topology data can, if necessary, to contain information about the total number of the input contact points (output contact points) each group of input (output) port. This information can is about to compare with information about the compounds employed in hashed table to obtain accurate information about there is at least one available hand, and on the basis of this comparison, it is possible to get exactly the established order connectivity for TMN, if the answer is positive, or deny the appeal to the TMN, if the answer is negative.

Although the present invention has been described using a number of specific examples, it should be understood that can be offered to other embodiments of the network management system, which allow to obtain solutions for connectivity for its managed network elements at the level of the SSA, through the creation and use of General rules of connectivity, and modified methods of using such SSA, although all such variants of execution/methods should be considered as part of the concept of the present invention.
