[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.
