Problems solved by technology

[0007] The present invention realizes the acceleration of local UDP protocol traffic in the client by solving the problem of correctly obtaining the original destination address of the data packet after the UDP data packet is redirected to the local agent in the UDP protocol traffic acceleration process generated by the local application

Embodiment Construction

[0012] The invention makes it possible to accelerate the UDP protocol flow generated by the local application in the client by correctly obtaining the destination address of the local UDP protocol data packet after being redirected.

[0013] According to an embodiment of the present invention, relying on Iptables to direct the flow to the local agent, the acquisition of the original destination address of the UDP protocol data packet in the local agent and flow guidance are all implemented in the application layer. The acceleration scheme does not change key modules such as Netfilter and TCP / IP protocol stack of Linux.

[0014] see figure 1 , shows a schematic structural diagram of a system implementing the present invention, and the system includes a client 101 , an acceleration server 102 , and an origin station 103 . The client 101 includes a local agent 1012 and one or more local applications 1011 to be accelerated, both of which are at the application layer; the Netfilte...

Abstract

The invention discloses a method and a system for accelerating a UDP protocol. The system comprises a client, an accelerating server and a source station, wherein the client comprises a home agent located in an application layer, to-be-accelerated one or more home applications, and a network filter in an IP layer. After receiving a request, the home agent recognizes a redirecting request from a different application and queries the original destination address, and the destination address and the request are packaged and then transmitted to the accelerating server; the accelerating server analyzes the original destination address and agents the request, and a response is returned to the home agent; and after the home agent receives the response from the accelerating server, an accelerating record is queried, and the response is forwarded to the corresponding home application.

Description

technical field [0001] The invention relates to the User Datagram Protocol UDP protocol, in particular to a UDP protocol flow acceleration method and system. Background technique [0002] The UDP protocol is a connectionless protocol in the OSI reference model for open system interconnection. It is located in the fourth layer - the transport layer. It is the upper layer of the IP protocol. It is used to process data packets, mainly to compress network data traffic. In the form of data packets, it provides simple transaction-oriented information transmission services. It does not provide packet grouping, assembly, or ordering of packets. [0003] UDP protocol acceleration is usually divided into two links. The first link guides the UDP protocol traffic to the remote acceleration server, and the second link uses the acceleration server to proxy the UDP traffic. The usual practice of the first link is to redirect the UDP protocol traffic to the local proxy, encapsulate the UD...
