随着当前互联网诸多弊端的暴露,近年来学术界对未来网络展开了广泛深入的研究.其中,建立以内容为中心的网络(content-oriented network,CON)是未来网络研究中较有代表性的研究思路.CON打破了传统的“主机-主机”通信模式,将内容置于首要地位,引起学术界广泛关注.本文将结合目前国际上CON研究的现状,综述CON中的关键技术,介绍CON的研究背景和CON中涉及的命名、路由等关键技术,预测未来CON的研究热点和发展方向.%With the exposure of many shortcomings in nowadays internet, there haye been lots of studies deeply in the future network around academic circles recent years. Amount these studies, establishing a CON (content-oriented network) is one of the representative researches. CON which is attracting many researchers' attention no longer uses the traditional communication mode called "end-to-end", but focuses on what it transmits. In this paper, we present a comprehensive survey on the key technologies of CON. The study background of CON following with several key technologies including naming, routing, security and cache are introduced. At last we make a prediction on the research focus of future CON and the development direction.
