转发控制分离的IPv6路由器控制体系结构研究

Research on the IPv6 Router Control Architecture of Forwarding and Control Element Separation

路由器体系结构是决定路由器性能和功能的主导因素。一方面,路由器的功能需求越来越复杂;另一方面,为了满足转发性能需求,普遍采用硬件进行转发。为此,转发控制分离成为一种全新的路由器体系结构。本文在研究分析转发控制分离体系结构的基础上,提出了一种针对IPv6的转发控制分离路由器控制体系结构,并重点研究了转发与控制分离后所带来的问题,最后设计和实现了一个原型系统。

Router architecture is the main factor which determines the performance and functions. The router＇s function requirement is more and more complex and hardware forwarding is adopted widely. As a result, the architecture of forwarding and control element separation becomes a new one for routers. Based on the analysis of forwarding and control element separation, an IPv6 router control architecture is proposed. In this paper we concretely discuss the problems caused by forwarding and control element separation, and build a prototype system.
