一个安全的主动网络结构

A secure active network architecture

主动网络就是可编程网络,它允许包对通过路由器的路由元素进行编程。主动网络为中间节点提供处理代码的能力。和传统网络相比较,主动网络让用户拥有更多的权限,在数据传输的过程中,用户能为自己的选择进行计算,并能跟主动节点进行交流,选择适合当前网络状况和自身条件的路由。这篇文章重点是针对主动网络面临的威胁,用最简单的方法来解决主动网络的安全性和发展主动网络节点。

active networks have been described as programmable networks that allow routing elements to be extensively programmed by the packets passing through them. They provide the capability of executing code inside intermediate nodes. Compared to existing networks, active networks make user more powerful.User can perform computations of his own choice during the transmission of data and communi- cate with active node. At last, choosing a best routing that apply to the current state and his own conditions. Facing the threat of active network,in this paper our focus is on a simplest approach to develop an active network node and on the security of active network.
