Abstract

The present invention provides a cluster system, a processor and a cluster system redundancy method. The cluster system comprises a plurality of service nodes. The operating state of each service node is detected through a master-auxiliary determining module. Furthermore the master process and auxiliary process of each service process are determined and confirmed by the operating state of each service node, the processing capacity of each service node and the CPU processing requirement of service process. A service distributing module distributes the service information to the master process of each service process, which is confirmed by the master-auxiliary determining module. The system CPU resource is effectively used. The service processing capability of system is maximized in the multi-node cluster system.

Description

technical field [0001] The invention relates to the communication field, in particular to a cluster system, a processing device and a cluster system redundancy method. Background technique [0002] In a multi-node cluster system, each node deploys one or more processes to provide services to the outside world. Considering the reliability of the system, nodes and processes will be redundant, and the redundancy methods mainly include 1+1 active backup and N+1 load sharing. In the process 1+1 active / standby redundancy mode, the active process provides services, and the standby process does not provide services. Generally, mutually redundant processes are deployed on different nodes, so that node and process failures can be switched to other nodes to continue to provide services. [0003] In the prior art, the system configures processes according to CPU and memory resources of nodes. Take the cluster system composed of two nodes as an example, such as figure 1 As shown, pro...
