可信路由机理及关键技术

Research on Theory and Key Technologies of Trustworthy Routing

文章认为由于网络规模的增大以及节点移动、多宿主、网络流量工程等需求的不断增强,使得路由可扩展性、安全性、可靠性等问题凸显。尽管与可信路由相对应的理论技术方案不断提出,但未能从根本上解决网络路由的可信任问题。为此文章提出可信路由体系结构模型、可信域内路由、可信域间路由等新网络环境下的可信路由参考机制,并对可信路由涉及的关键技术,如映射可扩展技术、路由信任机制、多径路由技术、服务质量保证、路由监测管理技术,进行了研究和探讨。

Due to the increasing network size and the wide use of mobility, multi-homing and traffic engineering, some serious problems such as routing scalability, routing security and routing reliability, arise in the routing system. In spite of many theories and technologies proposed to address the problems, the issues associated with trustworthy routing still could not be solved fundamentally. Therefore, we present a trustworthy routing architecture model, and introduce the reference trustworthy routing mechanisms used in the inner-domain and among inter-domains individually. Meanwhile, several key technologies for trustworthy routing in the new network environment are discussed in this paper, including mapping scalability, routing trust schemes, multipath routing, quality assurance of services, and routing monitoring and management
