Abstract

The invention provides a multichannel processing method in a TCP/IP unloading engine. The method comprises the following steps: step 1, performing experiments and debugging through a field programmable gate array FPGA to realize the multichannel processing technology in TOE; step 2, fusing the multichannel processing technology in TOE in an ASIC chip of the TOE to perform network protocol processing; step 3, customizing a software interface, and selecting different channels through a port; step 4, in a TCP processing module, improving and defining an option part of a TCP header; and step 5, in handshake phase established by a TCP connection, during first time handshake, adding a source channel number of an active requester, and setting a target channel as zero as the same is not allocated at the moment. By adoption of the multichannel processing method provided by the invention, the working efficiency of the TOE is greatly improved while the problems of data congestion and connection interruption are solved, a parallel data transmission function of a multi-port TCP connection is realized, a high level protocol of hardware processing TCP/IP is realized, and reliable guarantee is provided for data transmission in a high-speed network environment.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a multi-channel processing method in a TCP / IP unloading engine. Background technique [0002] With the increasing development of Internet technology, the TCP / IP protocol family has become a standard network communication protocol. However, in a high-speed network environment, the traditional TCP / IP software protocol stack will consume too much CPU performance due to the characteristics of context switching overhead and redundant data replication. Reliable data shows that the current mainstream processors will not be able to meet the protocol when the network speed reaches 10Gbps. Processing performance requirements. Therefore, the TOE (TCP Offload Engine, TCP Offload Engine) technology of the hardware device processing protocol is usually used in the server or high-speed network environment. The TCP / IP protocol is divided into four layers from top to bottom: application layer, ...
