摘要：

针对传统的状态检测技术占用空间大以及软件实现速度慢的缺点,设计了基于硬件现场可编程门阵列(field programmable gate array, FPGA)的传输控制协议(transmission control protocols, TCP)状态检测系统,并提出了一种改进空间占用量的方法。仿真结果表明该设计能够根据接收到的数据流信息建立相应的状态表,并能对超时的TCP连接发出警告信息。在使用4M空间的情况下,本实验能够支持100万条量级的连接,其空间占用量远小于传统的状态检测系统。

Abstract:

According to the disadvantage of traditional state detection’s high occupied space and software implementation’s low efficiency, a TCP state detection system was designed based on FPGA(field-programmable gate array),and a new method was proposed aimed at decreasing the occupied space of state detection table.The result of simulation indicated that the program could establish state tables according to the received data flows and give a warning for the overtime TCP connections. When using 4M Bytes space, our experiment could support a magnitude of 1 million connections, the occupying amounts of the space was smaller than the traditional state detection.

Key words: FPGA; state detection; EMAC; TCP
