Proxy forwarding method and apparatus, proxy server and multi-level proxy network

Abstract

Embodiments of the present invention relate to the technical field of network communication, for example, to a proxy forwarding method and apparatus, a proxy server, and a multi-level proxy network, the proxy forwarding method being applied to a proxy server, the proxy server communicating with at least two other proxy servers, the proxy server serving as an entry proxy server, the method including: receiving a request message sent by a client; acquiring communication path information of the request message, and adding residual path information of the request message starting from the next-next-hop to the header of the request message; and sending the request message to the next-hop proxy server. In the embodiments of the present invention, the preferred communication path information is added to the header of the data message, so that each proxy server performs data forwarding according to the preferred communication path. Through the interaction between the client and the source server through the multi-level proxy server, the preferred path can be selected for data packet transmission, and the data transmission efficiency is high.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, for example, to a proxy forwarding method and device, a proxy server and a multi-level proxy network. Background technique [0002] When users use network applications, they generally send data access request packets to the origin server through the application client installed on the user terminal to obtain corresponding content. For example, video applications can send data access request packets to the origin server through computers. text to get the corresponding video content and play it. In the application acceleration network (Application Delivery Network, ADN), many applications are based on the User Datagram Protocol (User Datagram Protocol, UDP). Its network structure usually interacts between the client and the origin server through the UDP proxy server. The UDP proxy server is responsible for forwarding the request from the client to the origin...

Problems solved by technology

[0003] In the process of researching the prior art, the inventors found that there are at least the following problems in the related art: in the current ADN network, there is only one level of UDP proxy server in the UDP-based application network, and the UDP proxy server transmits the data message through the underlying router Sending to the source server, the optimal path cannot be selected through the routing method, and the data transmission efficiency is poor
