摘　　要：传统的被动网络在发展过程中遇到了一些难以克服的问题 ,如服务单一、源地址欺骗、多播中否定应答风暴等 ,主动网络为解决这些问题提供了新的思路 ,并受到了网络界的重视 ,在国际上已成为解决下一代网络体系结构的研究热点 .本文从体系结构的角度分析了被动网络的缺陷 ,并介绍了主动网络的基本特点 ,设计了一种主动网络体系结构框架 ,并利用代码存储和请求加载等技术实现了这种系统框架的主动网络原型系统 ANSoft.该原型系统既具备主动网络系统的基本特征 。Conventional passive network suffers some problems,such as simplex services, source address spoofing and implosion of negative acknowledgement in multicast, in the course of its development. Active Network lends a novel method to settle these problems, and be taken notice by network researchers. It has become the hotspot for settling the next network architecture. This paper analyses the shortcomings of the passive network in term of architecture. It introduces the essential characteristics, and designs a active network architecture. We have implemented a prototype system-ANSoft-with some novel technologies, such as code caching and demand loading. This prototype system possesses the essential characteristics of active network, and has its own characteristics.
