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

[0035] 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.

[0036] 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

The invention discloses a method and a device for realizing communication between single boards. The method comprises that: when constructing a message, a sending single board adds a priority processing sign into the message encapsulated with emergency information, preferentially sends the message into a management channel according to the sign and transmits the message to a receiving single board; and after receiving the message, the receiving single board preferentially resolves the message encapsulated with the emergency information according to the priority processing sign. Chips of master control boards are stacked and soft highways (HW) are established between the main control boards and service boards to simplify the structure of equipment, effectively transmit information, fulfill the aim of fast protection switching at the same time of saving side lines of a backboard and realize fastest information transmission and protection switching on links among the main control boards and between the main control boards and the service boards; therefore, the method and the device can improve the data communication capacity and protection capacity of the overall system under a simple system architecture.

Description

[0001] technical field [0002] The invention relates to the technical field of communication equipment, in particular to a method and device for realizing communication between single boards. [0003] Background technique [0004] 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 ...
