Method for realizing two-way load equalizing mechanism in multiple machine servicer system

Abstract

The present invention provides bidirectional load equalization system implementation method in multi computer server. It contains using one or more load equalization unit node composing load equalization system and connected with outer network; load equalization unit node to make load equalization to client-side request; through modifying data package target MAC address to make data package dispensing; when fed back data package in through load equalization system, dispensing to each load equalization unit node to make whole server system having bidirectional load equalization function; when load equalization unit node gone wrong gone wrong, through migrating request data package and feeding back data package to other load equalization unit node to realize high usability.

Description

technical field [0001] The invention relates to the field of computer technology, and specifically provides a bidirectional load balancing mechanism used in a multi-machine server system. technical background [0002] Due to the rapid development of the Internet, the rapid growth of various applications has greatly increased the number of visits to network servers, which has led to the emergence of multi-machine server systems (such as cluster systems, also known as cluster systems) to meet the growing variety of applications. kind of demand. Load balancing technology is the key technology in multi-machine server system. Its main function is to balance the load so that the entire multi-machine server system can achieve the best performance. At present, the load balancing system based on multiple load balancers is one of the most used solutions, but the current load balancing generally refers to the load on the client request data (also called uplink data) packets. balance...

Problems solved by technology

For the response data (also called downlink data) package returned from the server node, some systems directly return it to the client through the server node. At this time, there is no need to consider load balancing. In this case, the back-end server system ( Generally composed of server nodes interconnected through the network) exposed to the external network, the security of the system is not good; some systems use the Network Address Translation (NAT, Network Address Translation) mechanism (strategy), although the request data packet and the return data packet All go through the load balancing system to ensure security, but there are also two shortcomings. One is that the network address translation makes the overhead of the load balancing system relatively large, which affects the performance of the load balancing system; the other is that there is no load balancing for the returned data packets.
