Upgraded server cluster system and load balancing method thereof

Abstract

The invention discloses an upgraded server cluster system and a load balancing method thereof and relates to the field of server clusters. The upgraded server cluster system comprises a policy server and a plurality of download servers, wherein the policy server is a unified access entrance, a weight number is distributed to each of the download servers by the upgraded server cluster system, the weight number means the maximum access volume of the corresponding download server in unit time, the weight number of each of the download servers minus a real-time linking number of each of the download servers, then a residual weight number of each of the download servers is obtained, an information list , a weight number list and a residual weight number list of each of the download servers are stored in an accessible data base of the policy server or an accessible configuration file of the policy server by the policy server, and the information list of each of the download servers is corresponding to the weight number list and the residual weight number list of each of the download servers in a one-to-one mode. According to the upgraded server cluster system and the load balancing method thereof, through combining the number of communication terminal equipment which accesses to the download servers and the maximum access weight number of each of the download servers, and scientific dynamic scheduling and reasonable allocation of access requirements are achieved.

Description

technical field [0001] The invention relates to the field of server clusters, in particular to an upgraded server cluster system and a load balancing method thereof. Background technique [0002] With the development of communication terminal equipment software technology and the popularization of network access, various communication terminal equipment is growing exponentially and expanding. Under the constraints of cost and response speed, the network-based software upgrade method has gradually become the mainstream upgrade method. In this way, upgrading servers is gradually being widely used. The upgrade server system often needs to handle the upgrade request, logic processing, software download and other functions of the communication terminal equipment. The ability of a single upgrade server system to handle a large number of and more and more concurrent requests is limited. The requirements are getting higher and higher, and the high performance and high availability ...

Problems solved by technology

[0009] In comparison, sequential polling is easy to implement, but it does not consider the processing capacity of the upgraded server, and the overall performance of the upgraded server cluster system cannot be better played, while weighted polling is only a theoretical consideration of the processing capacity of the server. Assign weights to each upgrade server. For upgrade servers that provide upgrade download services, due to reasons such as network speed and software file size, it will take a long time to occupy network bandwidth and server processing capacity during the software file download process. In this case Down-weighted round robin cannot take into account the real occupancy status of each upgraded server

The minimum load priority scheduling takes into account the occupancy status of the upgrade server, but it lacks consideration of the real processing capacity of the upgrade server, and it also lacks consideration of the network speed and the long-term occupancy of the upgrade server due to excessive software files, making it difficult to really use the upgrade server. Maximum performance of the cluster system
