Inter-network communication method and device and load balancer

Abstract

The present invention discloses an inter-network communication method and device and a load balancer. The inter-network communication method and device and the load balancer are applied to any one network machine room. The method comprises: receiving any one server access request, wherein the server access request carries the external network IP address of a server; inquiring an internal network IP address having a mapping relation with the external network IP address in the pre-stored mapping relation of the external IP address and the internal IP of the server; and if the server corresponding to the internal network IP address does not belong to the network machine room, employing an internal network private line built in advance, and forwarding the server access request to the server corresponding to the internal network IP address. The inter-network communication method and device and the load balancer can provide stability guarantee for an inter-network communication function with no need for employing a third-party proxy server. The inter-network communication method and device and the load balancer can realize inter-network communication through adoption of the internal network private line between the network machine rooms of each network supplier, and can solve the safety problem of the inter-network communication based on the safety of the internal network private line.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a cross-network communication method, device and load balancer. Background technique [0002] With the development of the times and the advancement of science and technology, China's network providers are also emerging one after another, such as Southern Telecom, Northern Netcom, China Railcom, Great Wall Broadband, China Mobile, etc., facing a variety of network providers, online game players will Choose the right network provider according to your own region, habits and other factors. [0003] However, it has always been a function that needs to be continuously improved to enable online game players to access the game servers of other network providers across the network. [0004] In the current online game industry, a proxy server is generally used to realize cross-network communication. Specifically, when an online game player needs to access game servers of other network p...

AI Technical Summary

Problems solved by technology

Since the proxy server is generally managed by a third party, the stability of the function cannot be guaranteed

In addition, the proxy server uses a less secure external network to achieve cross-network forwarding, and security issues cannot be guaranteed
