Design And Implementation Of Dynamic Host Configuration Protocol DHCPv6

With the rapid development of the internet, it has been penetrate into everywhere in our daily life with a skyrocketing expanding speed. Nowadays people can access and enjoy the fun of internet via ton of available devices, but on the other hand they have to face a problem which is the draining of the IPv4address pool. From the perspective of long-term network development, People have to figure out an effective and permanent solution regarding this issue instead of patching and modify on the old system. For the occurring of this phenomenon, the replacement of IPv4with IPv6is inevitable. At present, data communications equipment’s compatibility towards IPv6is not as mature as IPv4. In this case, the implementation of IPv6and related protocols will do a significance benefit for the research.As an important part of TCP/IP, Dynamic Host Configuration Protocol is responsible for the configuration of IP address and network parameters. This article focus on an IPv6Dynamic Host Configuration Protocol for IPv6(DHCPv6)’s research and design. First, the author analyzes the improvement of IPv6protocol towards the existing IPv4protocol; then explore the configuration for the IPv6network address and network parameters and analysis the DHCPv6protocol in detail; introduce the DHCPv6protocol implementation design by means of "DHCPv6Common Module, DHCPv6Server, DHCPv6Client and DHCPv6Relay" afterwards. In addition, this thesis introduces an implementation of DHCPv6Snooping which is a security solution based on DHCPv6.Finally present the test process of this project.
