Abstract

The invention provides a WebSocket-transmission-based load balancing method and a device, and aims at saving network resource and improving distribution efficiency. The WebSocket-transmission-based load balancing method comprises receiving a first WebSocket request which is launched by the client-side via a short link; enabling the client-side to redirect to a server in server cluster according to load balancing strategy, and enabling the client-side to launch a second WebSocket request to establish a link with the redirected server. Due to the fact that the WebSocket-transmission-based load balancing method does not always occupy the bandwidth between the load balancer, on one hand, network resources are saved. On the other hand, due to the fact that the data interaction between the client-side and the server is conducted through the link established between the client-side and the server after the client-side and the server are established a link, therefore, compared with the prior art, the WebSocket-transmission-based load balancing method is capable of guaranteeing own performance of the load balancing device free from impact, so that distribution ability of load balancing is improved.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a load balancing method and device based on WebSocket transmission. Background technique [0002] With the popularization of Hypertext Markup Language (Hypertext Markup Language v5, HTML5), WebSocket technology is widely used. WebSocket includes the advantages of having a small header (only 2 bytes), the client and the server only need a handshake to establish a link and send data to each other, as well as real-time, full-duplex and other advantages. In network communication systems that have large and high requirements for scale, distribution capability, and availability, WebSocket is gradually used as its transmission bearer. As one of the important components of the system, the load balance device, its distribution efficiency also largely determines the performance of the entire system. The so-called load balancing provides a cheap, effective and transparent method to expand ...
