Problems solved by technology

Its disadvantage is that the load distribution is highly random, and it is easy to cause a very high load on a certain node. In addition, if multiple nodes fail at the same time, the probability of partial routing failure is relatively high.

Abstract

The invention discloses a load distributing method, device and server in a distributed cache system, which improves the usability, operating efficiency and stability of the system. The load distributing method of the invention comprises the following steps: filtering a local server node list and generating a temporary server node list, wherein the temporary server node list comprises the information of the server nodes capable of providing services; distributing load weight for all the server nodes in the list according to the state information and / or the load processing capacity of the nodes in the temporary server node list; and generating routing information according to the load weight of each server node, and indicating each server node in the list to update the local routing information.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a load distribution method, device and server in a cloud computing distributed cache system. Background technique [0002] Cloud Computing is Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization , Load Balance (Load Balance) and other traditional computer technology and network technology development fusion product. It aims to integrate multiple relatively low-cost computing entities into a system with powerful computing capabilities through the network. Distributed cache is a field in the field of cloud computing. Its role is to provide distributed storage services for massive data and high-speed read and write access capabilities. [0003] In the distributed cache system, the load distribution of server nodes is one of the key problems that are difficult to solve. The distributed cache system is co...
