摘 要
随着互联网的快速发展，特别是物联网的时代的到来，许许多多的设备都需要接入互联网，这对本来就不宽裕的IPv4地址是一个巨大的消耗，在这样的背景下，世界各国纷纷开展了对下一代互联网协议，就是IPv6协议的研究。我国在IPv6的研究方面非常积极，并于2004年底建成了世界上最大的纯IPv6网Cernet2网，在下一代互联网技术的研究方面取得了可喜的进展。但是IPv4向Ipv6的过渡并不能一蹴而就，在很长一段时间内两者会共存，那么如何平稳渐进地过渡到IPv6是必须要解决的一个问题。
同样，作为院校教学和科研的重要网络——校园网也面临着同样的问题，需要升级改造。但是整个网络从IPv4过渡到IPv6需要相当长的时间，我们不能一下把以前的IPv4网全盘否定，因此需要在原有的IPv4网络上研究如何接入到IPv6网络上。
本文根据北京职业中专校园网的现状，依托北京职业中专现有的网络设备，提出了以北京职业中专现有的校园网为基础的二期组网方案，然后在window平台下利用仿真平台对方案里提出的过渡技术进行了可行性验证，并得出一系列的结论。

Abstract
With the rapid development of Internet, especially the content of the arrival of the age of the Internet, many equipment need to access the Internet, the originally not bounteous IPv4 addresses is a huge consumption, in this context, the various countries began to the next generation of the Internet protocol, IPv6 is the agreement. In the research of Chinese IPv6 very positive, and at the end of 2004, built the world's largest pure IPv6 nets Cernet2 nets, in the next generation of the Internet technology made great progress. But the transition to Ipv6 IPv4 and can't overnight, in a very long period of time will both coexist, so how to smooth the transition to gradually Ipv6 is must to solve a problem.
Also, as a college teaching and scientific research of the campus network-an important face the same problem, need to upgrade transformation. But the whole network from IPv4 transition to IPv6 need quite a long time, can't we once the former IPv4 nets completely negative, so we need to the original IPv4 network research how to access to IPv6 on on the network.
In this paper, according to the present situation of college campus network yellow, yellow on the existing network equipment institute, put forward the existing yellow college campus network based network schemes for phase three, and then in the workbench window using simulation platform in the transition of the plan put forward the feasibility of technology verification, and to draw a series of conclusion.
