随着互联网规模的日益增大,路由系统的可扩展性问题也关系到互联网技术的发展。下一代互联网结构设计必须首先解决的关键问题就是互联网路由系统的可扩展性问题。互联网路由系统的可扩展性问题的影响因素较多,但主要的影响因素是:地址空间规模、路由聚合度以及拓扑特性。针对这三个关键因素,继而提出相应的解决方案,主要是从路由空间划分、改进可扩展路由算法、提高路由聚合度探索解决的关键技术。 With the increasing size of the Internet, the scalability of the routing system is also related to the development of Internet technology. The key issue that must be solved first in next generation internet structure design is the scalability of internet routing system. The scalability of Internet routing systems is affected by many factors, but the main influencing factors are the size of address space, the degree of routing aggregation, and the topological features. In view of these three key factors, and then put forward the corresponding solutions, mainly from the routing space division, improved scalable routing algorithm to improve the routing aggregation to explore the key technologies.
