Reasearch on TCP State Machine Reduction in Embedded Internet Kernel
EI内核中TCP状态机约简的研究

In Embedded Internet (EI) environment there are limited resources, so it is very difficult to realize a Internet in EI environment. In general some high performance processor and memory are used to solve the problem. It is clearly is the wrong way as it incurs additional development time, testing time and price. In this paper a proper method is presented which is based on TCP state machine reduction. In TCP/IP protocol suite TCP is the most complex protocol and consumed most resources. We delete unimportant and unnecessarily state in EI environment and simplify complex relations. All these reduction are complete transparent for user because the interfaces are untouched. According to the reduction principle proposed in paper we realize an mini EI kernel in a 8 bit processor, in this kernel there are full function Web Server and correlative protocols.
