Problems solved by technology

Although this solution does not need to add professional load balancing equipment, it cannot achieve the best load balancing effect
Because the response speed to specific types of probe messages is fast, it does not really guarantee that the load of the SSL VPN gateway is light. It may be that the network speed itself is very fast, or the client device is relatively close to the SSL VPN gateway, or other reasons

Abstract

The embodiment of the invention relates to a gateway load balancing method, a system and a client device as well as a Secure Sockets Layer (SSL) virtual private network gateway. Since the IP addresses of at least two SSL VPN gateways are stored in the client device, the client device can directly inquire the state parameters on at least two SSL VPN gateways, thereby selecting one SSL VPN gateway with the lowest load to access into the Internet. Thus, the invention can realize balanced SSL VPN gateway loads in a simple and reliable way at low cost.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a gateway load balancing method, system and client equipment. Background technique [0002] With the development of the Internet, more and more enterprises and institutions begin to adopt the Secure Socket Layer (Security Socket Layer, SSL for short) virtual private network (Virtual Private Network, VPN for short) technology to realize remote Internet access. SSL VPN technology is a technology that establishes one's own virtual private network through a public network and performs communication encryption protection through the SSL protocol. By deploying the SSL VPN gateway, a dedicated communication line is established between the SSL VPN gateway and remote users connected to the public network and located in different places, and a secure private network is opened up on the insecure Internet. [0003] With the gradual expansion of the scale of enterprises or insti...
