Abstract

The invention provides a method and a system for realizing TCP (Transmission Control Protocol) full-offload IP (Internet Protocol) cores for multi-connection management. The method comprises a hash value generation step, a connection management step, a sending management step and a timer management step. The IP core for realizing TCP unloading can be connected with different types of buses to serve as a protocol processor; by means of the IP core, TCP network data can be obtained on FPGA hardware, and the function of supporting network control and data receiving and sending is achieved throughthe data connection algorithm acceleration module, the dynamic reconstruction module and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a TCP protocol full offloading IP core method and system for realizing multi-connection management. Background technique [0002] High-speed Ethernet represented by Gigabit / 10 Gigabit Ethernet is currently widely used in data switching centers, data video broadcasting and other occasions that require high-bandwidth data, and can effectively realize large data aggregation and link aggregation on the network. in numerous Ethernet transport layers. The TCP protocol is connection-oriented. Due to the adoption of the connection management mechanism, the confirmation mechanism for data transmission, and the sliding window protocol for block data streams, reliable network connections can be provided while achieving high bandwidth. [0003] With the improvement of network speed, high-speed data transmission of TCP using ordinary network cards will occupy a large amount of CPU res...
