Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for generating a protection subnet.
Background
With the development of communication network technology, communication traffic is continuously increasing, and accordingly, the number of services and protection groups supported by a network element management system responsible for maintaining and managing network element devices is increasing, and meanwhile, a protection function is used more and more frequently in transmission system engineering as an important function of the network element management system, so that the time required for maintaining service protection is also increasing.
The protection system on the network element equipment consists of four parts, namely a detector, a controller, an actuator and a protocol transmitter, wherein the detector is responsible for detecting an alarm; the controller is responsible for the calculation of the protection protocol and the control of the whole protection system process; the executor is responsible for service switching; the protocol forwarder is responsible for Automatic Protection Switching (APS) protocol forwarding. In order to implement a Protection system on a network element device, a Protection group and port service, a multicast routing, a Protection mode, a high-order channel Tandem Connection Monitoring (TCM) working mode, an APS/Protection Communication Channel (PCC) overhead monitoring enable, and the like need to be configured in a network element management system.
The service protection sub-network is a subset formed by dividing a network element into networks according to the protection of a multiplex section, a channel layer, an electric layer and a client side, and the existing methods for configuring the service protection sub-network include two methods:
The first method is as follows: the single point configuration means that a protection group and a port service are sequentially configured on a network element through which the service passes, then related functions of the protection group and the port service, such as a protection mode, a TCM (trusted cryptography Module) working mode, APS/PCC overhead monitoring enable, multicast routing and the like, are configured, and finally, a fiber cable connection is configured and a protection subnet is searched.
The disadvantages of the first method are: configuring a protection group and a port service for a plurality of times, for example, if the service passes through 10 network elements, 10 protection groups need to be configured; the process of configuring the protection group and the port service is complex and is easy to make mistakes; the protection group related function is associated with the protection relationship port of the protection group, and the protection relationship port of the protection group needs to be remembered in advance when the protection group related function is configured each time.
The second method is as follows: and (3) protection view configuration, namely, automatically discovering services after configuring fiber cable connection, then creating protection sub-networks, protection groups and port services in a protection view, and finally configuring related functions of the protection groups and the port services.
The disadvantages of the second method are: the manual creation of the protection subnet has six steps, and each step needs a user to select or confirm configuration data, so that the configuration process is complicated; the protection group related function is associated with the protection relationship port of the protection group, and the protection relationship port of the protection group needs to be remembered in advance when the protection group related function is configured each time.
Therefore, for transmission system engineering, the existing method for configuring the service protection subnet has great limitation and cannot meet the requirements of testing and engineering.
Aiming at the technical problems of complex process and low efficiency of configuring a service protection subnet in the related technology, no effective solution is provided at present.
