摘要
信息中心网络(Information Centric Networking,ICN)作为未来网络的架构被提出,旨在解决基于主机的TCP/IP网面临的诸多问题。随着ICN领域研究的不断深入,目前面对的一个关键问题是ICN网与现有IP网的融合问题,这对于未来网络的发展与演进具有重要的意义。针对这一问题,目前学术界提出了几种解决方案,主要包括了TCP/ICN与HTTP/ICN的方案。文章首先就这两种方案进行了介绍与对比,然后以此为基础对IP/ICN的两网融合问题进行了展望,如何做到对现有协议或应用尽可能小的改动,如何充分利用ICN固有特性如网内缓存、多播等优势,是研究中需要重点关注的问题。
As an important proposal for future Internet architecture,ICN is proposed to solve some problems in TCP/IP-based Internet which is host-reachability.With the deepending of research in ICN,a key problem we are faced is network integration between TCP/IP and ICN,which has great importance for the development of future network.Aimed at the problem,researchers have raised several schemes,including TCP/ICN and HTTP/ICN.In this paper,we first introduce the two schemes and make a comparison between them,and then look forward to the prospects of the future research.In future research,what is important is making great use of ICN's inherent properties such as caching,multicast.How to make as little change as possible on current protocols or applications is also what we should pay attention to.
