Cluster arbitration method and multi-cluster coordination system

Abstract

The embodiment of the invention discloses a cluster arbitration method and a multi-cluster coordination system. The method in this embodiment of the present invention includes: detecting whether a fault occurs in a first group of clusters or a second group of clusters, wherein the first group of clusters includes a part of the first cluster and a part of the second cluster, and the second group of clusters includes Another part of the first cluster and another part of the second cluster, the first cluster and the second cluster cooperate with each other; when a fault is detected, the first group of clusters and the second group The clusters respectively determine their own preemption representatives, and the preemption representatives of the first group of clusters and the preemption representatives of the second group of clusters respectively perform the following steps: determine whether there is a fault in the group cluster where they are located; Perform preemption, wherein the preemption of the arbitration device that succeeds in preempting the arbitration device according to the preset arbitration mechanism represents the survival of the group cluster it belongs to. The invention can reduce the probability of service access interruption.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cluster arbitration method and a multi-cluster coordination system. Background technique [0002] Active-active data centers mean that both data centers are running and can undertake business at the same time, improving the overall service capability and system resource utilization of the data center. The two data centers are mutual backups. When one of the data centers fails, there will be zero data loss, and the business can be automatically switched to the other data center. [0003] An active-active data center usually consists of a storage layer, a network layer, and an application layer. Several clusters are deployed in the active-active data center. Part of each cluster is located on one side of one data center, and the other part of each cluster is located on the other side of the data center. The sub-clusters of each data center work together . [0004] However, ...

AI Technical Summary

Problems solved by technology

[0004] However, the arbitration mechanism of each cluster in the active-active data is different. When a failure occurs, each cluster adopts its own arbitration mechanism for arbitration, resulting in that the arbitration results of each cluster may not be consistent, that is, some clusters may be located in one of the data The sub-clusters in the center survive, some clusters in another data center survive, and then the entire business access is interrupted probabilistically
