Research on Active Network Technology

论述了主动网络出现的背景、主动网络的主要技术及其优点，着重阐述了主动节点模型，按照主动网络封装协议的规范，利用ＡＮＴＳ实际开发出一个ｐｉｎｇ程序示例说明。探讨了主动网络在安全性、性能和互操作性等方面改进的措施，并对其在可编程网络中的地位给予了评价。

In this paper, the background, main technology and the benefit of active network are reviewed. The active node model is mainly focused and a ping program which is based on the active network encapsulation protocol specification and the active node transfer system tool is developed to introduce active network technology. In the end, the improved method of security, performance and interoperability is put forward and its vole in the programming network is discussed.
