Application & Research Of Embedded Ethernet Technology

With the development of the microelectronics technology, embedded system has been adopted and widely used in a wide range of fields concerning the family life as well as the industrial production, such as household appliances, mobile communication, network instruments, and industrial control. Now the number of embedded system has surpassed that of all kinds of general computers. On the other hand, Internet has become one of the most important and necessary communication establishments. But embedded system is generally independent of the Internet. With the development of technology and the increase of practical demands, Internet should not be confined on information management level. And it is necessary for embedded system to realize remote measure, control and share information. So how to connect the embedded system to Internet has become a more and more important problem. Applying Ethernet and TCP/IP technology to embedded system is called "embedded Ethernet technology". This thesis discusses and explores the realization and application of embedded Ethernet technology.This thesis introduces the features of embedded TCP/IP protocol, then analyzes embedded TCP/IP protocol from embedded field, and puts forward the overall design model and some details. This paper does some deep research on some basic TCP/IP protocol, such as ARP, ICMP, IP, UDP, TCP in order to improve the real-time character. This thesis also proposes some new algorithms to modify traditional ones. In the final part of this thesis, the author studies the application of embedded Ethernet technology in intelligent communication control system.
