现有路由系统面临来自可扩展性、移动性、多宿主以及流量工程等方面的挑战,已经不能满足客观需求.基于位置与标识分离的思想,提出了标识路由的概念并对其研究范围进行了精确的界定.根据标识路由的设计目标,还详细介绍和比较了国内外相关的研究工作.最后提出标识路由研究的若干关键问题,并对未来的研究方向做出展望.
With the rapid development of Internet technology,the existing routing system has been confronting many serious challenges of scalability,mobility,multi-homing and traffic engineering.Based on the idea of Identifier/Locator Split,the concept of identifier-based routing is proposed,and its research scope is accurately defined in this paper.On the basis of the design goals of identifier-based routing,some related researches are introduced and compared.Finally,some key issues and the development trends are discussed.
