Description

Backboard, method and device for analyzing message, method and device for realizing communication

Technical field

This document relates to, but is not limited to, the field of optical transmission, and in particular to a backplane, a method and apparatus for analyzing a message, and a method and apparatus for implementing communication.

Background technique

In the WDM product monitoring system, the electrical monitoring information is implemented by the General Communication Channel (GCC) in the optical transport network (OTN, Optical Transport Network) service overhead.

The electrical monitoring channel realizes communication between the network elements of the optical transmission network and transmits the monitoring information. The electrical monitoring is carried out by means of a path, and the GCC bytes of the service overhead of the optical transformation unit (OTU) are transmitted together with the service. The way to transmit network management monitoring information through GCC bytes is also a communication method between network elements.

In the OTN overhead, GCC is a non-interfering channel for transmitting information between OUT terminals, and has three overheads of GCC0, GCC1, and GCC2, each of which occupies two bytes. Among them, GCC0 is located in the 11th and 12th columns of the first row of the OUT overhead, GCC1 is located in the 4th row, the 1st and 2nd columns of the OUT overhead, and GCC2 is located in the 4th row, the 3rd and 4th columns of the OUT overhead.

Since the implementation of multi-channel GCC in the OTN electric monitoring system has no relevant international standards, there are different implementation schemes for different equipment manufacturers. FIG. 1 is a schematic diagram of related implementation of multi-path GCC. As shown in Figure 1, there are one or more backplane slots on the backplane. Each backplane slot has a backplane network port. The related service boards include CPU daughter cards, logic chips, and switch chips. . The data forwarding between the backplane network port and the CPU daughter card and the logic chip is implemented by using a switch chip. The CPU subcard and the logic chip are connected to the switch chip through a network interface. One end of the backplane network port is connected to one port of the switch chip through a connector, and the other end of the backplane network port is connected to the interface of the backplane. The electrical monitoring communication message transmitted on the electrical monitoring channel between the backplane and the CPU daughter card is unlabeled (UNTAG), and the electrical monitoring communication message transmitted on the electrical monitoring channel between the backplane and the logic chip is Label (TAG), and each electrical monitoring channel will automatically assign a separate virtual local area network (VLAN). In this way, different electrical monitoring channels are separated by different VLANs, and at the same time, electrical monitoring information transmission of multiple GCCs is realized.

The backplane network port of the related backplane is connected to the switch chip through the connector. In practice, the service board needs to be inserted and removed multiple times, which may cause the backplane network port to fail. In this way, the service board will not be able to conduct services, and no effective solution has been given in the related art.
