Method and system for multiplex and connection management of a load balancer

Abstract

The invention provides a method and a system for multiplex and connection management of a load balancer. The method for multiplex and connection management of the load balancer comprises that the load balancer receives a user request from one application or a plurality of applications and puts the user request into a queue and records connection information of the user request; a connection manager makes sure whether a free connection exists in a connection pool or in a plurality of connection pool, wherein the connection pools are provided with a maximum number of connections and a minimum number of connections; if no free connection exists, the connection manager creates a new connection and allocates the newly-created connection to the load balancer, and if a free connection exists, the connection manager allocates the free connection to the load balancer. The load balancer transmits the user requests to a corresponding server through the allocated connection and forwards response data from the corresponding server to a user.

Description

technical field [0001] The present invention relates to a connection management and multiplexing method, and more particularly relates to a connection management and multiplexing method of a load balancing device. Background technique [0002] With the development of the Internet, the data volume of network services is increasing, and at the same time, higher requirements are put forward for the high availability of applications. The server master / standby redundancy mode can no longer meet the current needs. Therefore, in a large-scale network service architecture, load balancing devices are usually used to forward user requests to back-end real servers. [0003] A load balancing device is a set of servers composed of multiple servers in a symmetrical manner. Each server has an equivalent status and can provide external services independently without the assistance of other servers. Through a certain load sharing technology, the requests sent from the outside are evenly dis...

Problems solved by technology

Moreover, such an implementation takes up a large number of connections and increases the load on the real server

Moreover, the increase in the number of connections will add a lot of overhead to the system

It can be seen that the number of connections is a great limitation for the server

[0005] In order to solve the problem of the number of connections, the existing solutions include: 1) Actively disconnect the connection to the user on the load balancing device, which can reduce the number of connections to the backend server, but may cause the user to request that the connection be reset

2) Keep the connection to the user on the load balancing device, and actively disconnect the connection to the back-end server, which will cause the load balancing device to frequently establish and close the connection to the server
