Problems solved by technology

[0002] In the field of communication, the ATCA (Advanced Telecom Computing Architecture) architecture is very mature in the application of active and standby control and management chassis, but at the same time, there are active and standby failures or other reasons that the switching is too slow, which is far from meeting the needs of customers.

Embodiment Construction

[0014] The technical solution of the present invention will be further described in conjunction with specific drawings and embodiments.

[0015] The present invention provides a fast master-standby switching control method, such as figure 1 and figure 2 As shown, the specific implementation process of the method is as follows:

[0016] In the first step, the power-on hardware reset is completed and the CPU writes the board control register to reset. The FPGA obtains the board slot number through the board slot register and opens the communication channel, and uses CRC and parity check to pass the master and backup status information in real time. The sending module and the active / standby state information receiving module accurately obtain the state information of each other's single board.

[0017] In the single board slot register, the position of the even-numbered slot is set to 0, and the position of the odd-numbered slot is set to 1.

[0018] The power-on hardware inc...

Abstract

The invention discloses a quick main and standby switching control method, and belongs to the technical field of communications. The control method comprises the steps that after electrified hardware is reset, two single boards are in real-time communication to acquire the state information of the single boards; after the single boards control a register to feed a dog, the single boards start competing; if the state of a main and standby state register of the current single board is changed, an interrupt pulse signal is generated to inform a CPU and the opposite single board, the opposite single board collects communication information and judges to adopt the corresponding main and standby switching processing mode. According to the method, main and standby switch can be quickly achieved, and the service suspension phenomenon caused by slow switching is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and mainly relates to the fast switching control between the master and the backup of the ATCA framework in the communication field. Background technique [0002] In the field of communication, the ATCA (Advanced Telecom Computing Architecture) architecture is very mature in the application of active and standby control and management chassis, but at the same time there are active and standby failures or other reasons that the switching is too slow, which is far from meeting the needs of customers. Contents of the invention [0003] The purpose of the present invention is to provide a control method supporting fast active-standby switchover, said active-standby switchover control method comprising the following steps: [0004] In the first step, the power-on hardware reset is completed and the CPU writes the board control register to reset. The FPGA obtains the board slot number through t...
