Policy based service load balancing method

Abstract

The invention discloses a server load balance method based on the strategy, solving the problem that the prior content transport network is incapable of knowing the differences of servers, learning the current statuses of the servers, and leading the customer to the equipment which has a lighter load. The server load balance method based on the strategy includes the steps as follows: (1) the turn process records the load condition of each server; (2) when the customer demands to the service, the invention chooses the server which has the lightest load serving for the customer. The present invention provides a high efficiency load balance method and has a low cost, making the whole loads in the node are distributed uniformly, achieving a real load balance.

Description

technical field

[0001] The invention relates to a content delivery network (CDN), in particular to a policy-based service load balancing method. Background technique

[0002] The content delivery network CDN is to optimize the distribution of content in the network, so that the most popular content is distributed in the edge node closest to the user. When a user requests content, the global redirector gives priority to using the node closest to the user and having content to serve the user. Generally, a node must be able to support thousands of users. In addition to providing video services for users, the streaming media server also undertakes many tasks such as content pull-down, uploading, recording and broadcasting, etc., which puts high demands on the service capabilities of the streaming media server. , so in order to solve this problem, consider using multiple streaming servers to serve users, that is, distributing user access to multiple servers, which not only incre...
