IPv6 Analys And Research On Home Gateway

With the rapid development of network technology and information appliances, the ever-growing number of Internet users and smart appliances promoting the number of home networks increase rapidly, integrating the traditional home of the original stand-alone devices and functions, building a powerful and personalized embedded home gateway system for exchanging the communication and data between home network equipment and Internet, formating the intelligent home network sector have become the focus of research.As an important part of the intelligent home, Home gateway plays a central role in the home network, it interconnects the home network or smart devices and external networks to share high-speed broadband connection. As the interface between home networking and broadband services, the home gateway plays an important role at the digital home network. The research, application and improvement of new technology will offer a variety of home network business, which will become the powerful weapon for the telecom operators to shape their own core competitive capacity in the information age.Home gateway is the result of microelectronics, computer technology, multimedia technology and network technology's development, it's also the merge of software, hardware and network technologies. It's used to connect the home network or device with the Internet, share the high-speed connection broadband, provide more convenient lifestyle for people at the information age. So home gateway is the inevitable product of the family network at the information age.With the high reliability, lower cost, small size and other characteristics, embedded home gateway has become the research focus of the network communication industry, the operational and expansion capacity of embedded home gateway are gradually increased, IPTV, VOIP, USB Storage/print sharing,3G, and many other new applications are emerging.Based on the MIPS32 and the master chip RTL8672, building an embedded home gateway. Analysised of the characteristics of IPv6 and the advantages of the IPv6 in the home network; Introduced the function of the home gateway system, related protocols, new technologies and trends; Describes the overall design based on RTL8672 hardware and software framework design. Reaserched the implementations and applications of the IPv6 and the solution of coexistence between the IPv4 and the IPv6 protocol; Finally, based on the system security considerations, the IPv6 firewall was applied to the embedded home gateway system.
