摘要
当前的互联网体系结构是基于终端间包交换的点到点连接通信架构。随着实时视频、话音等通信业务量的日益激增,由于TCP/IP体系固有结构的束缚,互联网传输、处理这些实时多媒体数据的能力受到越来越大的挑战,体现在效率低下、用户体验差。信息中心网络应运而生,它将内容与终端位置剥离,通过对内容进行命名和基于内容名字的路由开展了对互联网体系结构变革的研究探索。
The current Internet architecture is based on packet switching between the end to end communication architecture.With the growing surge of multimedia traffic and other communication services,especially video traffic,this architecture comes under increasing challenges in delivering contents over the Internet due to the obstacles of its inherent structure,which results in low content distribution efficiency,long retrieval latency and poor user experience etc.Information-Centric Networking（ICN） comes into being and tries to rescue this situation in this context.ICN separates content with the place where it stored,and brings out a new hot wave in research for the future Internet architecture.
