基于移动Agent的网络管理框架及实现

Ｉｎｔｅｒｎｅｔ／Ｉｎｔｒａｎｅｔ的迅速发展，促使网络日趋复杂，规模不断扩大，应用服务数量剧增，网络管理的重要性日益提高。传统上作为事实工业标准的ＳＮＭＰ采取攻功能固定的代理机械地收集大量原始数据，逐渐无法适应网络的发展现状，大量网管信息加重了网络负载，对管理对象的请求响应缓慢。

NETWORK MANAGEMENT BASED ON MOBILE AGENT:ARCHITECTURE AND IMPLEMENTATION

With the rapid development of Internet/Intranet, network is becoming larger and more complex. Traditional SNMP based centric network management can no longer keep up with these trends. In the paper here, a new framework is put forward, which takes advantage of the mobile agent to manage network more quickly and more flexibly. In the new framework, an agent execution environment resides on the network device, substituting the old SNMP's function static agent. Network management center selects proper agent program according to network state and distributes it to network device where instance is generated to fulfill the expected task. Mobile agent not only can collect data, but also can process these data to improve the response and relieve NMS's burden. The mobile agent structure and its control strategy are presented. A management framework with its prototype, which can integrate with SNMP, is also described.
