Description

Protection subnet generation method and device

Technical field

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

Background technique

With the development of communication network technology, the communication traffic is continuously increasing. Accordingly, the number of services and the number of protection groups supported by the network element management system responsible for maintenance and management of network element devices are also increasing. At the same time, as an important function of the network element management system, the protection function is used more and more frequently in the transmission system engineering, which leads to more and more time for maintenance service protection.

The protection system on the network element device is composed of four parts: detector, controller, actuator and protocol transmitter. The detector is responsible for detecting the alarm; the controller is responsible for the calculation of the protection protocol and the control of the entire protection system flow; Responsible for business switching; the protocol transmitter is responsible for automatic protection switching (APS) protocol delivery. In order to implement the protection system on the NE device, you need to configure protection group and port services, multicast routing, protection mode, and high-end channel tandem connection monitoring (TCM) working mode and APS in the NE management system. / Protection Communication Channel (PCC) overhead monitoring enable.

The service protection subnet is a subset of the network element that divides the network according to the multiplex section/channel layer/electric layer/client side protection. There are two methods for configuring the service protection subnet:

The first method is: single-point configuration, that is, the protection group and port services are configured in turn on the service network, and then the protection group and port service related functions are configured, such as protection mode, TCM working mode, and APS/PCC overhead monitoring. Enable, multicast routing, etc. Finally configure the cable connection and search for the protection subnet.

The disadvantages of the first method are: the number of times that the protection group and port services are configured. For example, if the service passes through 10 NEs, you need to configure 10 protection groups. The service process of configuring protection groups and ports is complicated and error-prone. It is associated with the protection group protection relationship port. Each time you configure a protection group related function, you need to remember the protection group protection relationship port in advance.

The second method is to protect the view configuration. After the cable connection is configured, the service is automatically discovered. Then, the protection subnet, protection group, and port services are created in the protection view. Finally, the protection group and port service related functions are configured.

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. The configuration process is cumbersome; the protection group related function is associated with the protection group protection relationship port. When configuring a protection group related function, you need to remember the protection relationship port of the protection group in advance.

It can be seen that for the transmission system engineering, the existing method for configuring the service protection subnet has a large limitation and cannot meet the test and engineering requirements.

In view of the technical problems of configuring the service protection subnet in the related art to be complicated and inefficient, an effective solution has not been proposed yet.
