Embodiment Construction

[0035] Functional Overview

[0036] The embodiment of the present invention provides a master / standby card switching scheme, which not only keeps the switching mechanism simple but also meets the requirements of multi-processors, the processing principle of the scheme is: establish the main processor, and only the main processor Run the active-standby switchover control software module; each processor program is responsible for its own fault monitoring, but all the faults of all processor programs on each board are uniformly classified, and the active-standby switchover control software module is based on the comprehensive final fault level to decide whether to switch.

[0037] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0038] In the followi...

Abstract

The invention discloses a method and a system for switching main / standby board cards. The method comprises the following steps: determining one processor as a first main processor from a plurality of processors of a main board card and all of other processors as auxiliary processors; determining one processor as a second main processor from a plurality of processors of a standby board card and all of other processors as the auxiliary processors; determining a fault level of the main board card according to the fault of the auxiliary processors of the main board card and the fault of the firstmain processor by the first main processor; determining the fault level of the standby board card according to the fault of the auxiliary processors of the standby board card reported by the second main processor and the fault of the second main processor by the first main processor; and switching the main board card and the standby board card according to the fault level of the standby board card and the fault level of the main board card. The invention simplifies the switching of the main / standby board cards of a multiprocessor.

Description

technical field [0001] The present invention relates to the communication field, in particular to a master / standby board switching method and system. Background technique [0002] At present, in the communication equipment that requires high reliability, the active / standby backup of single boards is basically adopted. The purpose of active / standby backup of single boards is that when the current active single board fails, another standby single board can take over the work of the failed main board in time to maintain the normal operation of the entire system. [0003] The reasons for board master / standby switchover can be roughly divided into three categories: [0004] 1. Manual request switching (background man-machine command switching). [0005] 2. Fatal failure of the main board (for example, the main board is pulled out, the main board is powered off, the heartbeat signal of the main board is lost, and the main board is reset, etc.). [0006] 3. A non-fatal failure o...
