主动网络路由器及其应用

The Active Routers and Its Applications

主动网络是一种可编程的网络,用户可以对网络进行个性化的编程和设置。主动网络与传统的网络仅仅被动地传送字节流不同,它是“运行时刻可扩展的”。在主动网络体系结构中,可以快速动态地定制、配置新的网络服务和开发新的技术与协议,实验新的网络体系结构。加快了网络服务的革新步伐,提高了网络的性能,使得网络体系结构更灵活、更具有可扩张性。该文在介绍了主动网络的产生背景、实现方案、网络模型和它的优点之后,提出了一种高性能的主动网络路由器的实现方案,并针对该实现方案给出了该路由器的一些典型应用。

A ctive Network is a paradigm for data networks in which the network is designed n ot merely to forward packets,but also to be dynamically programmed in order to support per-user services.It can be extended while running,and fastly be con figured and managed.The network have the advantages of faster deployment ,cust omization of network services,equipped with new network protocols and architect ures,etc.After introducing the background,implementation,models and advantag es of the active network,this paper presents an implementation of the high perf ormance active router and some applications.
