Problems solved by technology

[0006] In practical application, the above solution has the following problems: when the master device fails and performs master-standby switchover, that is, during the switchover process, the service being provided may be interrupted, which expands the scope of the fault and reduces the availability of the device
Even if part of the CPUs on the original master device are working normally, they will be forced to switch, so that the services that can be provided normally are forced to be interrupted

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The invention monitors the operation status of each processor main control process on the equipment unit by setting the monitoring process on the monitoring node. When the monitoring process finds that the master control process of the non-master processor is abnormal, that is, when the processor fails, only the faulty processor is switched through this process, and other normal processors continue to provide services without switching, thereby improving the system Service Availability. At the same time, a process is set on the main control processor of the equipment unit as the main control process for the operation and management of the entire equipment unit. When the main control process of operation and management fails, in order to ensure the manageme...

Abstract

The present invention relates to a major standby protection technique of communication equipment, and discloses a major standby protection method of multiprocessor equipment unit. When a processor is failed, the service of other normal processors in said equipment unit can not be interrupted. Said invention is characterized by that the equipotent processor of every equipment unit is set in major standby protection group, when one processor is failed, the correspondent protection group can make replacement of single processor only. Every equipment unit possesses a main control processor, when said processor produces abnormal state, the whole equipment unit can be replaced.

Description

technical field [0001] The invention relates to the main-standby protection technology of communication equipment, in particular to a multi-processor device unit main-standby protection method. Background technique [0002] Currently, the highest indicator of system availability is five nines, or 99.999% system availability (equivalent to 5 minutes of outage for a year). To achieve this target, the traditional solution is to build a very stable set of equipment and systems. However, such a system is very expensive, difficult to upgrade and develop, and the system stability is very dependent on the manufacturer's hardware and software configuration. With the development of communication networks towards diversified services and packet-switched data, there is a contradiction between the rapidly developing market customer needs and the slow development of merchant equipment functions. Customers require merchants to provide products with complete functions and excellent usabil...
