Problems solved by technology

When the server server2 is deleted, obj1 is stored in server1, obj2, obj3, and obj4 are stored in server3), which causes the distribution of cluster object servers to be very unbalanced, resulting in unbalanced server load

Abstract

The invention discloses a server balancing method based on a hash algorithm. The server balancing method comprises the steps that the data annular space of a cluster server environment is constructed, the key value of each object set is calculated by using the hash algorithm, the corresponding objects are hashed to the data annular space according to the key values, corresponding servers are mapped to the data annular space and the objects and the servers are correlated by using a clockwise mode, and the objects on the servers are migrated by using a clockwise migration mode when the servers are added and deleted. The objects can be greatly mapped to the corresponding servers by using the hash algorithm so that migration of mass data can be avoided, the pressure of the servers can be reduced, and the server cluster is enabled to be greatly processed when facing mass data volume and high concurrent system performance; meanwhile, the unbalancedness of the load servers can be effectively reduced by configuring virtual nodes so that the utilization rate of the server nodes can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of cluster servers, and in particular relates to a server balancing method based on a hash algorithm. Background technique [0002] With the rapid development of the Internet and the increasing number of Internet users, a single service certainly cannot meet the service needs. The cluster service model has gradually become popular. Using cluster servers as the background, a major problem is to solve the problem of load balancing. The traditional balancing algorithm is mainly persistent and non-persistent server balancing. Persistence means that a specific client sends a request and will be served by the same server. The persistent algorithm is mainly based on the random theory, that is, the default client access is random, so the server The selection is also random, so as to achieve load balancing. The disadvantage of the persistence algorithm is that it is not easy to update dynamically. For example, the ha...
