The network education software and protocol hierarchies 分層教學網絡軟件的設計與實現
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 本文以嵌入式系統的接入網技術為研究,在分析嵌入式系統網絡連接的結構體系和協議層次基礎上,提出一種新型基于因特網的嵌入式網絡體系結構。
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 然后針對大家都很熟悉的tcp ip協議進行了簡單的描敘,在此基礎上,分析了嵌入式tcp ip協議與操作系統tcp ip的不同之處,指出了嵌入式tcp ip的基本設計原則,并探討了嵌入式tcp ip協議棧的通信協議層次模型、總體結構體系、各個協議工作的主要流程,還列舉了一個實際應用的嵌入式tcp ip協議的例子進行說明。
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 Tcp是一種面向連接的可靠傳輸層協議,最初是針對有線網絡設計的。由于有線網絡鏈路可靠性高,傳統tcp認為丟包和亂序是由網絡擁塞所導致。然而,在manets中,眾多非擁塞因素導致了丟包和亂序。
