基于Smart Packets的主动网络管理模型研究

The Research of the Active Network Management System Model Based on Smart Packets

主动网络是一种新型的网络体系,它不仅可以传送数据包,而且还可以执行数据包中特定的运算任务。主动网络为用户提供了可编程的接口,用户可通过网络中的节点动态地注入所需的服务。Smart Packets采用紧缩格式和安全代码编写其中的程序,它能够支持主动网络管理。本文讨论了传统网络管理中存在的问题,分析了主动网络管理体系结构与管理机制。重点研究了Smart Packets的结构、管理机制、包的格式、编程语言和设计目标,以及安全性。

Active network is a new framework where network nodes not only forward packets, but also perform customized computation on the packet flowing through them. It provides a programmable interface to the user where users dynamically inject services into the intermediate nodes. Smart Packets programs are written in a tightly-encoded, safe language specifically designed to support network management. This paper analyzes the problems of tradition network management, the structure and mechanism of the active network management system. It introduces Smart Packets and describes the Smart Packets architecture, the mechanism of management, the packet formats, the language and its design goals, and security.
