The network education software and protocol hierarchies
2.
The body under study is the technology of the accessing network of embedded system on network . a new network - based embedded networks architecture was given based on the analysis of the architecture of embedded system net net correction and protocol hierarchy
3.
And then the well - known tcp / ip protocol is simply presented . the paper analyzes the difference of embedded tcp / ip protocol and standard tcp / ip protocol and gives the basic designed principle . also in this paper , the communication protocol hierarchy , general architecture and each protocol " s main processes are discussed in embedded tcp / ip protocol , and the practical applied embedded tcp / ip protocol is made out
4.
Specifically , for the first time all factors impairing tcp performance are identified based on network protocol hierarchy , i . e . , lossy wireless channel at the physical layer ; excessive contention and unfair access at the mac layer ; frail routing protocol at the network layer , the mac layer and the network layer related mobile node ; unfit congestion window size at the transport layer and the transport layer related asymmetric path
