One-way proxy method and system based on dpdk

Abstract

The invention discloses a DPDK-based one-way proxy method and system, the method comprising: the proxy end guides according to the border routing guidance protocol and uses DPDK to receive the response message of the response terminal; the proxy end modifies the response message of the response message The original header information is new header information, and the mapping relationship between the original header information and the new header information is established at the same time, and the modified response message and the mapping relationship are sent to the agent 2 according to the new header information end; the proxy end restores the response message according to the mapping relationship, and sends the restored response message to the requesting end according to the original header information. The present invention does not change the original connection relationship between the requesting end and the responding end, has the advantages of high performance, no need for connection resources, and small memory usage, well avoids the problem of exhaustion of resources such as ports, memory, and connections, and also solves the problem of connection Time and request response time distortion issues.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a DPDK-based one-way agent method and system. Background technique [0002] In the current network environment, the redundancy of network traffic is high, and users have higher and higher requirements for network response speed. It is often necessary to accelerate user traffic, redundant deletion and other optimization techniques to improve bandwidth utilization and user experience. In order to accelerate or optimize user traffic, the traffic is usually directed to an acceleration or optimization environment through a proxy or other means for processing. [0003] In the traditional proxy mode, the proxy forwards the request message by redirecting the user. In actual implementation, the client establishes a connection with the proxy server, and the proxy server establishes a connection with the request response server. It needs to be fully transparent to users and...

Problems solved by technology

[0004] In the above-mentioned traditional proxy method, because the proxy server needs to participate and establish connections, in the scenario with a high number of connections, the frequent establishment and release of connections greatly affects the performance and is prone to port exhaustion; At the same time, for each connection, the system needs to create a connection tracking item and allocate some memory resources when processing it, which is prone to exhaustion of memory and connection resources

[0005] Moreover, in the usual deployment scenarios of traditional proxies, the proxy server and the client are usually a LAN, and its network delay will be much smaller than the WAN network delay between the client and the server, because in the proxy scenario, It is actually the proxy server that completes the connection establishment with the client, which will cause the connection establishment speed perceived by the client to be faster. However, because the response content still needs to be sent by the server after receiving the request, the client will eventually perceive the connection. The establishment speed is faster, but the illusion of slower server response speed, resulting in distortion of connection time and response time
