Below with reference to graphic materials and the preferred variants of the invention will be described in detail, the technical scheme of the present invention. One example of the present invention provides a method of restoring service CCTV, as shown pas 1, which includes: 101. sharing information about the failure points of presence (POPs) in different types and formulation of measures to restore service surveillance in accordance with various types of information about the failure. 102. obtain information about the refusal of the current POP; and 103. the implementation of measures to restore service surveillance in accordance with information about the failure according to the type of information about the failure. The present invention will be described in detail below with respect to specific examples, which, however, does not limit the scope of protection of the present invention. This example provides si is theme to restore service video as shown PA FIGURE 2, which includes: a dividing module, a receiving module, a switching module, and communicating to the module. In combination with FIGURE 2, the method of restoring service surveillance provided for in this example, as shown in FIGURE 3, includes the following steps: At step 301 dividing module divides the information about the failure points of presence (POPs) in different types and formulates measures but to restore service surveillance in accordance with various types of information about the failure. In particular, the dividing module divides the information about the failure POP on "saturation performance to service the client node (CU)", "saturation performance for service predose (EN)", "deviation from the norm of the space of the disk array pop", "deviation from the norm pop", "saturation performance of service pop", etc. Where a measure to restore service surveillance formulated for refusal related to the chip "saturation performance for service CU", may be the switching of CU from the current POP POP in the backup. Measure to restore service surveillance formulated for refusal related to the type of "saturation performance for maintenance PU", can be switched PU from the current POP POP in the backup. Where the saturation capacity for maintenance of the air traffic management PU includes filling the space of the disk array and/or the excess of the number of access PU predefined maximum number POP access. Measure to restore service surveillance formulated for refusal related to the chip "deviation from the norm of the space of the disk array pop", can be switched PU current POP from the current POP POP in the backup. Measure to restore service surveillance formulated for refusal related to the type of "POP deviation from the norm"can be switched PU and CU current POP from the current POP POP in the backup. Measure to restore service surveillance formulated for refusal related to the type of "saturation performance POP for service"may be switching overloaded PU and CU current POP from the current POP POP in the backup. At step 302, the receiving module receives information about the refusal POP. Where POP in this example represents a logical block mainly composed of four streaming services and one shared disk array, as seen PA FIGURE 4. It should be noted that POP may also consist of three streaming services and two shared disk arrays, and this example is not limiting. In particular, the maximum number of access PU, the maximum number of access CU, the space of the disk array, etc. are preset in the POP. Where information is received about the access, the reported CU, and access information includes: nome is access CU. The system compares the number of CU with a pre-specified maximum number of access CN order to determine whether the access number CU predetermined maximum number of access CN, and, if exceeded, determines that the performance of POP for service CU is saturated, and receives information about that performance for service CU is saturated, as information about the failure of current POP. Accepted access information reported by PU, and access information includes: the number of access PU. The system compares the access number PU with a pre-specified maximum number of access PN with the aim of determining whether the access number PU predefined maximum access number PN, and if exceeds, determines that the performance of POP for maintenance PU saturated, and receives information about that performance for service PU saturated, as information about the failure of current POP. Accepted access information reported by PU, and access information includes: the space of the disk array occupied by the PU. The system compares the space of the disk array occupied by the PU, with the remaining space of the disk array current POP the purpose of determining whether the space of the disk array occupied by the PU, the remaining space of the disk Massi is and current POP, and, if exceeded, determines that the performance for service PU saturated, and receives information about that performance for service PU saturated with information about the failure of current POP. Accepted information about the deviation from the norm of the space of the disk array, the reported current POP or obtained during preliminary observations, and information about the deviation from the norm of the space of the disk array is accepted as information about the failure of current POP. Accepted information about the deviation from the norm of the current POP reported current POP or obtained by preliminary observations, and information about the deviation from the norm of the current POP is accepted as information about the failure of current POP. For example, if the proxy POP server experiences a failure, the information of the proxy server that is experiencing the failure is reported to the system as the information about the deviation from the norm of the current POP. Information is received that is saturated with the performance of the current POP to service, inform you of the current POP or obtained by preliminary observations, and information indicating that the performance of the current POP for maintenance saturated accepted as information about the failure of current POP. For example, when there is a refusal streaming service current POP in the course of its work, the current POP tells about the refusal streaming SL is gby as an information system about the performance of the current POP to service the rich. At step 303, the Executive module executes the appropriate measure to restore service surveillance according to the type of information about the failure. In particular, if the type information about the failure is the saturation capacity for service CU, Executive module switches CU from the current POP POP in the backup. If the type information about the failure is the saturation capacity for service PU, Executive module switches PU from the current POP POP in the backup. If the type information about the failure is a deviation from the norm of the space of the disk array POP, Executive module switches PU current POP from the current POP POP in the backup. If the type information about the failure is a deviation from the norm POP, Executive module switches PU and CU current POP from the current POP POP in the backup. If the type information about the failure is the saturation performance of the service POP, Executive module switches overloaded PU and CU current POP from the current POP POP in the backup. Where the switch out of the current POP back in POP is a switching service surveillance of current POP POP back in accordance with the descending order of priorities backup POP; if the priority of the backup POP the same service surveillance plumage is luchetta from the current POP in a relatively unoccupied POP back according to the policy of balancing. In particular, switching between POP depends on the preset dependencies between POP, as shown in FIGURE 5, which illustrates the dependency relationship that is set to POP, where the dependency relationship is established between each POP, and all other POP and set priorities. For example, the priorities of the nodes can be defined according to the principle of proximity POP, and when the service needs to be restored by switching, the service automatically switches to POP with a higher priority, and when the priorities are the same, the service is automatically switched in a relatively unoccupied POP according to the policy of balancing. In particular, as shown in FIGURE 5, when PU and CU ROR need access to other POP refusal POP1, will be selected POP5 with a priority of 4. As shown PA 6, it illustrates the switching POP and mainly describes a scenario in which a PU CU and b of the n PU and CU m ROR switch in ROC, where n>=a, m>=b, m, n, a and b are non-zero natural numbers. At step 304 after the Executive module execution starts informing module to inform the user about the execution. In particular, the informing module informs the user through an emergency signal indicating that the switch must perform hand with this is Yu, or on account of automatic switching, for example, about the reason for the switch POP, the track switch, switch, etc. Based on the same concept with features of the invention, a method of one example of the present invention provides a system for recovering service surveillance, as shown in figure 2, where the system includes: separating module, which is used to separate information about the failure points of presence (POPs) in different Tina and formulates measures to restore service surveillance in accordance with various types of information about the failure. a receiving module, which is used to obtain information about the refusal of the current POP; and the Executive module, which is used to perform measures to restore service surveillance in accordance with information about the failure according to the type of information about the failure. In addition, the receiving module, in particular, is used for receiving access information reported CU, where the access information includes access number CU; comparing the access numbers of CU with a pre-specified threshold number to determine whether the access number CU pre-defined threshold number of access; if exceeds - define what performance for CU saturated, and accept that the capacity to service the CU rich information about the failure of the current POP; accordingly, the Executive module is used for switching of CU from the current POP POP in the backup according to the information about what performance to service the CU rich. In addition, the receiving module, in particular, is used for receiving access information reported PU, where the access information includes access number PU, comparing the access number PU with a pre-specified threshold number to determine whether the access number PU pre-defined threshold number of access, and, if exceeded, determining that the capacity to service the PU is saturated, and the adoption of information about what performance to service PU full of information about the failure of the current POP; and/or receiving access information reported PU, where the access information includes the space of the disk array occupied by the PU, the comparison space of the disk array occupied by the PU, with the remaining space of the disk array current POP to determine whether the space of the disk array occupied by the PU, the remaining space of the disk array current POP, and when it exceeds, the definition of what performance to service the PU on isana, and accept the fact that performance for service PU full of information about the failure of the current POP; accordingly, the Executive module is used to switch PU from the current POP POP in the backup according to the information about what performance to service PU saturated. In addition, the type of fault information received by the receiving module represents information about the deviation from the norm of the space of the disk array, the reported current POP or received in the course of preliminary observations: accordingly, the Executive module, in particular, is used to switch current PU POP from the current POP POP in the backup according to the information about the deviation from the norm of the space of the disk array.
