Problems solved by technology

The disadvantage of this method is that it is difficult to ensure the timeliness of the master-standby state decision-making and intercommunication information between the master and the backup, especially when the master-standby switchover occurs or when the more serious master-standby switchover occurs frequently, which often leads to management failures. Temporary or long-term disconnection of the channel

Embodiment Construction

[0030] In view of the fact that too many dedicated HW bus channels will cause too many backplane side wiring, this embodiment proposes a concept of soft HW. The main idea is to simulate a dedicated channel in the management channel instead of A separate channel is established on the hardware to ensure the timeliness of information transmission such as alarms and switching, which not only saves lines on the backplane side, but also achieves the effect of a dedicated high-speed channel.

[0031] The implementation of the soft HW bus can, for example, add priority processing marks to packets that encapsulate emergency information, so as to realize rapid transmission of emergency information such as alarms, overhead, heartbeat, and switching control between boards. This solution does not need to increase the connection between each service board and the main control board, but uses the existing management channel between the main control board and the service board, which can be FE...

Abstract

A method and an apparatus for realizing communication between single boards are provided by this invention. The method includes the steps: a sending single board adds a priority processing sign into a message encapsulated with emergency information when the message is being constructed, and preferentially sends the message via a management channel to a receiving single board according to the priority processing sign. After receiving the message, the receiving single board preferentially resolves the message encapsulated with the emergency information according to the priority processing sign. Wherein, the sending single board or the receiving single board is a main control board. By means of a soft HW channel established between the main control board and the service board and the chips stacking of the main control board, the present invention simplifies equipment, efficiently transmits information, saves the circuit at the back board, realizes quick protection switching, and achieves quick information transmission and protection switching on both links between the main control boards and between the main control board and the service board, thus improving the data communication capability and the protection ability of the system with the simple system structure.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a method and device for realizing communication between single boards. Background technique [0002] Communication equipment generally adopts the structure of the main control board (NCP) and the service board. The clock board is usually integrated with the main control board. The service board includes the cross (switch) board, interface board, line board and tributary board. There are one or more channels between the main control board and the service board, and the main control board is responsible for the management and monitoring of each service board. The service board needs to report various status information regularly or irregularly, such as alarm, overhead and heartbeat information. The protection switching control center is generally set on the main control board, and the main control board issues switching control information after processing the alar...
