应用于嵌入式系统的TCP简化实现方法

A Simplified Implementation of TCP on a Small-size Embedded System

该文介绍了一种适用于嵌入式系统的TCP实现方法,符合RFC1122的兼容性规范,而代码的规模只有BSDTCP的30%。该实现强调对TCP的简化,以提高可靠性;同时应用了几种简化的TCP优化技术以提升性能,包括头部预测、重传回退。该TCP无须操作系统的支持,假定整个IP栈运行在裸机上。

This paper describes the way how to implement TCP on a small-size embedded system.This implementation is compliant with RFC1122.And the size of this implementation is shortened as nearly half size as the BSD TCP.How to simplify TCP is the focus point.And this paper introduces several shortened TCP improvement techniques,including Header Prelibation,Retransmission Roll-back.This implementation is based on the bare machine,where doesn't need the support of OS.
