摘要： 随着互联网络应用范围越来越广，新的需求层出不穷，但是这些新需求中有相当一部分仅仅是为了少量的应用而提出的。这就对下一代的网络体系结构提出了非常重要的一个要求：必须能够在不同的时间、不同的区域满足重要程度不同的各种需求。这一要求导致了主动网络概念的提出。该文介绍了主动网络的概念、主动路由器的体系结构、硬件体系结构及主动网络的应用。

Abstract: As the applications of the Internet grow more and more popular, many new requirements keep appearing. But most of the new requirements are put forward just for few applications. So there's a very important requirement for the next generation network architecture: it must satisfy different requirements at different time and different area. This requirement leads to the concept of active network. This article introduces the concept of active network, the architecture of active router, the currently presented hardware architecture, and applications of the active network.
