Interrupt reconnection quick response method and device and communication equipment

Abstract

The invention relates to an interrupt reconnection quick response method and device and communication equipment. The device comprises a main control board, a standby control board and at least two service boards. Each service board is connected with the main control board and the standby control board through communication channels. CPUs and switching network chips are arranged in the main controlboard, the standby control board and the service board. Each CPU is connected with the corresponding exchange network chip through a high-speed data communication bus, and the main control board, thestandby control board and the service boards are suitable for closing alternative channels of the service boards according to main and standby states of the main control board when main channels of the service boards are normal; enabling the connection of the main channels of the service boards; when the main channel of a certain service board is abnormal, the exchange network chip of the serviceboard monitors whether the alternative channel of the service board is normal or not, and if yes, connection of the alternative channel of the service board is enabled. According to the invention, the interruption time of a local communication channel fault can be shortened, and the reliability and switching efficiency of products are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and communication equipment for rapid response to interruption and reconnection. Background technique [0002] In some communication devices, the main control board needs to interact with the service board through the communication channel, such as software upgrade, configuration delivery, status monitoring and other data and control signals. The problem that the business is interrupted is generally to realize the active and standby redundancy protection of the communication channel between the boards, so as to enhance the reliability of the communication channel between the boards. [0003] The CPU of the traditional service board and the CPU of the main / standby main control board use the analog switch to select the Ethernet switch chip connected to the main control board according to the main and standby status of the main control board to realize...

AI Technical Summary

Problems solved by technology

[0004] 1) Simulate a single-pole double-throw switch, and the connection status of the backup channel cannot be monitored. If the connection of the backup channel is interrupted, the communication between the boards may be interrupted after the switchover

[0005] 2) The analog switching rate is low. According to the barrel effect, the communication channel between the boards can only reach 100M at most. The current mainstream communication interface of the CPU has reached 1000M, which greatly wastes the bandwidth of the communication interface.

[0006] 3) If the inter-board communication between one of the service boards and the main control board is interrupted, while other service boards are normal, the main control board can restore the communication with all service boards only after the active / standby switchover occurs, thus causing the communication channel of one service board to be broken. The abnormality causes the analog switches of the main control board and the service board to switch, which not only affects a large area, but also interrupts the business for a long time
