Network load balancing and control method and apparatus, and network interaction method and apparatus

Abstract

The invention provides a network load balancing and control method and apparatus, and a network interaction method and apparatus. The method comprises the following steps: receiving a preset flow scheduling rule sent by a control device and unique path indication information of a back end server in a second type network; obtaining the unique path indication information of a client in a first type network from a back end server access request sent by the client; sending the back end server access request to a back end server selected according to the preset flow scheduling rule; receiving request response information returned by the back end server, and returning the request response information to the client according to the unique path indication information of the client, wherein the unique path indication information is unique in the first type network where the client is located and the second type network where the back end server is located, and at least one of the first type network and the second type network is a virtual private network VPC. By adoption of the scheme of the invention, the address conversion processing of the client and the back end server requires no gateway.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a network load balancing method and a network load balancing device, and a network load balancing control method and a network load balancing control device, as well as a network An interaction method and a network interaction device. Background technique [0002] With the development of Internet technology, the access traffic borne by the server from the client is becoming larger and more frequent, and the scalability of the server is becoming more and more important. In order to facilitate client access, multiple extended back-end servers are usually virtualized into one virtual server to unify the interface for providing external services. Between the client and the backend server, the load balancer (Load Balancer, LB) usually dispatches the access traffic to the backend server (Real Server, RS) that actually provides the service according to a certain algorith...

AI Technical Summary

Problems solved by technology

[0005] During the client's access to the back-end server, the original VPC addresses of the client and the server need to be converted by the gateway. low problem

In addition, after the gateway conversion process, the load balancer cannot know the real network address of the client, and cannot accurately access and control the client.

Furthermore, address translation also consumes traditional IP addresses
