基于IPv4/IPv6双栈机制的高校网络改造研究

Research on university network reconstruction based on IPv4/IPv6 dual stack mechanism

在国家战略的推动下,高校都展开了IPv6网络的建设工作,但从IPv4网络向IPv6网络的过渡是一个漫长的过程,面对当下各高校现网的实际情况,需要制定一个系统的、科学的、可行性高的IPv6建设方案,进行有步骤、分层次的建设。文章将从高校IPv4网络建设的实际情况出发,分析IPv6与IPv4特性上的优势差异及IPv6组网规划设计中应重点考虑的若干问题,给出基于双栈协议的3层组网架构和大二层扁平化组网架构的IPv6校园建设实例。

Under the promotion of national strategy,colleges and universities have carried out the construction of IPv6 network,but the process transition from IPv4 network to IPv6 network is long,facing the current and the actual situation of the existing network of colleges and universities,to formulate a systematic,scientific and feasible IPv6 construction plan,carry out step-by-step and layered construction.Based on the actual situation of IPv4 network construction in colleges and universities,this paper analyzes the advantages and differences between IPv6 and IPv4 characteristics and some key problems that should be considered in IPv6 network planning and design,and gives examples of IPv6 campus construction based on three-layer network architecture and two-layer flat network architecture.
