The Research And Realization Of Embedded Internet System Based-on IPv6 Protocol

With the fast development and widely application of the Internet, more and more people are focusing on the rich resources of the Internet. Connecting and visiting are the most urgent in IT field. During "the post-PC time", today the embedded Internet system has substituted the PC and become the main way to connecting and visiting the Internet.Currently, the application products of embedded Internet systems are mostly realized by high-powdered 32-bits MCU embedding the TCP/IPv4 protocol. But there are a series of problems to prevent the embedded Internet system getting applications on a large scale, such as the high price and long develop periods of 32-bits MCU, the drying up IPv4 address and unsafe network delivering.After having analyzed the principles, the main functions and the leading problems that demanding to solve about the embedded Internet system, and at the same time according to" the accommodation is the best" this guide policy, the thesis have bringing forward and designing a 8-bits embedded system which is made by 8-bits MCU embedded Internet protocol vision 6, namely "design of the embedded Internet system based on IPv6 protocol". In addition, the thesis also take industry producing "network data gathering system" as discussing and researching subject", in order to introducing the hardware and software design of the embedded system base on IPv6.In the course of research, a few of technologies involved, which is the basis and guarantee fulfilled: 1 the hardware of the system used the cheap price 8-bits MCU and Ethernet control chip, and via the Ethernet to connect the Internet and to finish data receiving and sending; 2 introducing the IPv6 protocol in this system's software, IPv6 protocol is the next generation internet standard, it reserve many successful characters with IPv4 and provide some more powerful function in order to meet new requirement, and it success to solve the problem about the IP address scarcity; Moreover, for the sake of saving the limited system resources, the system adopts thesimple circularly control and also reduces the complicated IPv6 protocol to carry on the basic function which can assist the system to achieve the data from the Internet. The research of the key technique is the base and guarantee of the function of the system.The Bringing forward and carrying out about the embedded Internet system base on IPv6 protocol urge more and more single machines which are used in our everyday life to connect the Internet conveniently, thus solved the problems that the information and resources need to be shared among the equipments. So that it has the remarkable social and economic results.
