一种主动网络通信平台的设计与开发

Design and Develop of Communication Platform for Active Network

当具有可编程特点的主动网络技术应用到网络管理系统中时,网管终端与主动节点之间以及主动节点与主动节点之间的交互,主动代码的加载等需要得到基础通信服务的支撑。本文主要针对我们提出的基于主动网络的面向业务的网管系统的具体通信需要,分析了应该具备的通信功能,设计了执行环境和主动信包封装格式,基于分布式的主动代码存储机制实现了主动代码的动态加载,从而设计和开发了一种主动网络通信平台。该平台在网管原型系统得到了运用,从运用结果看它能够较好的进行主动代码的动态加载,能够提供基础的通信服务。

When the active network technology with the programmable characteristic is applied to the network management system, many scopes need to be supported by communication services, such as the interaction of network management terminal and active nodes, as well as between active node, and the active code dynamic loading. In order to meet the communication requires of the service - oriented network management system proposed by us, this paper analyses communication functions, and designs the structure of execution environmental and the encapsulation format for active packet. At the same time, the function of dynamically loading active code is implemented based on the Distributed Code Caching for Active Network and a communication platform is implemented. This platform has been applied to the network management prototype system. The application results show that this platform can dynamically load active code and can provide the basis of communications services.
