一种新型主动式网络体系结构模型

A New Active Network Architecture Model

主动网是一种允许用户“按需”定制自己的服务的可编程网络。由于允许用户编程,主动网不但应具有较好的可编程性,而且应具有较好的性能和安全性。文章基于组件和安全语言技术提出了一种新的主动网体系结构模型----Ac-tiveWare。它包括网络基础设施、协议件和主动包三个层次。基于这一模型,用户可以利用协议件安全、方便地在主动网上构建自己的服务。

Active networks,which allow users to customize their network services arbitrarily,are programmable.Since they can be programmed,active networks must balance the flexibility and convenience of programming network infrastructure against safety and security requirement inherent in sharing that infrastructure.This paper,based on software component and security programming language,introduces a new active network architecture-- - ActiveWare,which consist of net-work infrastructure,protocol components,and active packet.Based on this model,users can construct their network ser-vices safely and conveniently.
