ICN内容路由研究与实现
发布时间：2018-11-21 14:14
【摘要】：随着互联网的飞速发展,互联网的使用方式也由原先的计算与通信逐渐转变为对内容的共享。当今基于TCP/IP的现有互联网的体系结构也暴露出与网络需求不匹配的现象,如内容分发效率不高,对移动设备支持不好等问题。信息中心网络(ICN)有支持Multi-homing,安全性高,移动性支持好等特点,现在已经成为互联网体系结构研究的热点。 ICN通过名字来标识内容,使之成为以内容为中心的网络,使获取内容更加高效,灵活。国内外主要的ICN项目有DONA、CCN、PSIRP、 NetInf等。这些ICN系统与当今互联网兼容性差,在现实网络中部署面临诸多难题,难以短期内发挥效果。设计一个与当今互联网兼容的ICN系统首先要考虑的方面在于路由。本文首先提出分层的方案,可以使路由策略更加灵活。然后在区域(Region)内外分别实现了基于时延的路由方案和基于跳数的路由方案。接着提出通过路由聚合的减轻内容路由器路由表的方法以及通过路由实现缓存的负载均衡方法。最后在测试部分通过对区域内路由方案,区域间路由方案和区域内外互通方案三个场景的模拟表明我们设计的ICN路由能够兼容TCP/IP网络,按照分层的策略灵活路由。
[Abstract]:With the rapid development of the Internet, the use of the Internet has gradually changed from the original computing and communication to content sharing. The current architecture of the Internet based on TCP/IP also exposes the phenomenon that it does not match the network requirements, such as inefficient content distribution, poor support for mobile devices, and so on. Information center network (ICN), which has the characteristics of high security of Multi-homing, and good mobility, has become a hot topic in the research of Internet architecture. ICN uses names to identify content and make it a content-centric network, making content acquisition more efficient and flexible. The main ICN projects at home and abroad are DONA,CCN,PSIRP, NetInf and so on. These ICN systems have poor compatibility with the Internet today and face many difficulties in deploying in real networks, so it is difficult to give full play to the results in the short term. Routing is the first consideration in designing a ICN system compatible with today's Internet. In this paper, a hierarchical scheme is proposed, which can make the routing policy more flexible. Then the delay-based routing scheme and the hop-based routing scheme are implemented within and outside the region (Region). Then, the method of reducing the routing table of content router by routing aggregation and the load balancing method of cache by routing are proposed. Finally, in the test part, the simulation results of the intra-regional routing scheme, inter-regional routing scheme and inter-area interworking scheme show that the designed ICN routing is compatible with the TCP/IP network and can be routed flexibly according to the hierarchical strategy.
