Problems solved by technology

This quadruple traffic results in a doubling of the traffic in the demilitarized zone
Moreover, when the network isolation zone adopts a single-layer active-standby mode to realize the load balancing architecture, the performance upper limit is the upper limit of the performance capacity of a single load balancing device, and the device hardware must be replaced when the performance is expanded.

Abstract

The invention provides a load balancing system applied to a network isolation area. The system comprises an access layer, a security layer and a function layer. The access layer is used for receivingan access data stream arriving at the network isolation area and distributing the access data stream to the security layer so as to carry out load balancing on equipment in the security layer; the security layer is used for performing security check on the access data stream and forwarding the data stream passing the security check to the function layer; and the functional layer is used for distributing the received data stream passing the security check to a background server so as to carry out load balancing on the background server. The invention further provides a load balancing method applied to the network isolation area.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and more specifically, to a load balancing method and system applied to a network isolated area. Background technique [0002] The network demilitarized zone (DMZ, demilitarized zone) is to solve the problem that the access users of the external network cannot access the internal network server after installing a firewall, and a buffer zone between a non-secure system and a secure system is set up. Access traffic from the external network needs to pass through the network isolation zone before reaching the real server in the background, so that the internal network can be more effectively protected, and there is another barrier for attackers from the external network. [0003] In related technologies, the network isolation area usually adopts a single-layer active-standby mode to realize the load balancing architecture, especially when security layer devices such as web application ...
