Embodiment Construction

[0038] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose, the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0039] Such as figure 1 As shown, in related technologies, the proxy service between client A and server B is a pseudo-transparent technology, such as haproxy, and the proxy process is:

[0040] Client A initiates a link establishment request to server B, proxy server P intercepts the link establishment request, and pretends to be server B to complete the 3-way handshake with client A;

[0041] When client A initiates a service request, proxy server P pretends to be client A to establish a link with server B and initiates the request;

[0042] Server B sends a response message to proxy server P, and the proxy service process receives the response message and searches for the link of client A; proxy server P finds t...

Abstract

The invention provides a message forwarding method and device for a heterogeneous network, and the method comprises the steps: receiving a link building request transmitted by a client, and forwardingthe link building request to a server, so as to build the connection between the client and the server; and forwarding the interaction message between the client and the server based on the user modeprotocol stack. According to the message forwarding method of the heterogeneous network, forwarding of the message is completed on the transmission layer, the problem of proxy service performance bottleneck caused by multiple copies of the message in the user mode and the kernel mode in the forwarding process can be avoided, message zero-copy forwarding based on the user mode protocol stack is realized, and the system performance is effectively improved. Moreover, according to the message forwarding method provided by the invention, a man-in-the-middle does not need to be forged, the risk ofman-in-the-middle attack does not exist, encrypted transmission of TLS and the like is supported, and the safety and reliability of message forwarding are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message forwarding method and device for a heterogeneous network. Background technique [0002] The network on the network server side is very stable and supports high-concurrency and high-throughput user requests. The wireless mobile network has its specific transmission characteristics, such as out-of-order packet forwarding, inability to accurately and timely determine packet loss, and resource shortage during busy hours. The sudden change has affected the online experience of mobile users. [0003] Traditional proxy technology is mainly based on forward proxy and reverse proxy technology. The proxy service establishes TCP connections with both ends of the communication, that is, the proxy service needs to establish a TCP connection with the access client and a TCP connection with the server, and then establishes a TCP connection with the server. The session...
