Description

Method and device for generating protection subnet

technical field

The present invention relates to the field of communications, and in particular, to a method and device for generating a protection subnet.

Background technique

With the development of communication network technology, the traffic volume of communication is increasing continuously. Correspondingly, the number of services and protection groups supported by the network element management system responsible for the maintenance and management of network element equipment is also increasing. At the same time, the protection function, as an important function of the network element management system, is used more and more frequently in transmission system engineering, resulting in more and more time required to maintain service protection.

The protection system on the network element equipment consists of four parts: detector, controller, actuator, and protocol transmitter. The detector is responsible for alarm detection; the controller is responsible for the calculation of the protection protocol and the control of the entire protection system process; the actuator Responsible for service switching; the protocol transmitter is responsible for automatic protection switching (Automatic Protection Switching, APS for short) protocol transmission. In order to realize the protection system on the NE device, it is necessary to configure the protection group and port services, multicast routing, protection mode, Tandem Connection Monitoring (TCM) working mode, APS/ The protection communication channel (Protection Communication Channel, PCC for short) overhead monitoring is enabled, and the like.

The service protection subnet is a subset formed by dividing the network elements according to the multiplex section/channel layer/electrical layer/client side protection. There are two existing methods for configuring the service protection subnet:

The first method is: single-point configuration, that is, configure the protection group and port services in sequence on the network elements that the services pass through, and then configure the protection group and port services-related functions, such as protection mode, TCM working mode, and APS/PCC overhead monitoring. Enable, multicast routing, etc., and finally configure fiber and cable connections and search for protection subnets.

The disadvantage of the first method is that there are many times to configure protection groups and port services. For example, when services pass through 10 NEs, you need to configure protection groups 10 times; the process of configuring protection groups and port services is complicated and prone to errors; protection group related functions It is associated with the protection group protection relationship port. Each time you configure the protection group related functions, you need to remember the protection group protection relationship port in advance.

The second method is: protection view configuration, that is, after configuring the fiber and cable connection to automatically discover services, then create protection subnets, protection groups and port services in protection view, and finally configure protection group and port services related functions.

The disadvantage of the second method is that there are six steps to manually create a protection subnet, and each step requires the user to select or confirm the configuration data, which makes the configuration process cumbersome; the protection group-related functions are associated with the protection group protection relationship ports, and each time When configuring protection group related functions, you need to remember the protection relationship port of the protection group in advance.

It can be seen that, for transmission system engineering, the existing method for configuring service protection subnets has great limitations and cannot meet the requirements of testing and engineering.

Aiming at the technical problems of complex and low efficiency in the configuration of the service protection subnet in the related art, no effective solution has been proposed so far.
