Abstract

The invention discloses an improved load balancing algorithm based on difference feedback, which comprises the following steps: a threshold value of CPU residual utilization ratio of a server clusternode and a threshold value R (Si) of node load difference value in the cluster are set; The load balancer collects the CPU remaining utilization ratio of the server cluster node in a certain time interval, and calculates the load difference delta L (Si) of the cluster node; and the load balancer collects the CPU remaining utilization ratio of the server cluster node in a certain time interval; theload difference value of cluster node is compared with the threshold value of the set load difference value and the current CPU remaining utilization ratio of cluster node with the threshold value ofthe CPU remaining utilization ratio set before, a group of clusters with the highest node load weight value are selected, and the user request is distributed to the cluster node with relatively highweight value.

Description

Technical field

[0001] The invention relates to the algorithm field of server cluster service quality, in particular to an improved load balancing algorithm based on a difference feedback type. Background technique

[0002] With the rapid development of the Internet, user access to the network is also rapidly increasing, and the needs of various services have become diversified, which has led to a sharp increase in the load of the network, and it has become more difficult to handle user access. It cannot serve a large number of users concurrently The problem of access also arises. The invention uses the knowledge of the cluster to solve the Web service, and achieves the purpose of improving the service quality of the server.

[0003] The most commonly used load balancing algorithms are divided into dynamic load balancing and static load balancing. Among them, static load balancing is to distribute tasks according to a certain proportion, such as: round-robin load (RR) and weighte...
