一种基于IP的主动节点结构模型设计

主动网络是一种新型的网络体系，它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。本文提出了一种基于IP选项的主动网络体系结构，分析IP数据报的格式，扩展IP数据报选项域的定义，通过在其中嵌入代码，可在现有的IP网络上实现主动技术，扩展网络服务。

The Design of the Structure Model of Active Network Based IP

Active network is a kind of novel network architecture; it provides a programmable interface to the user where users dynamically inject services into the intermediate nodes. This paper bring forwards a structure of active network,analyses the format of the IP datagram and extends the definition field to supports the embedding of the program in datagram which can realize the active networks technology in IP network and extend the service in existence network.
