管理站点和管理代理通信设计

对简单网络管理协议中管理信息和协议数据单元进行扩充,设计并实现面向应用软件的网络监控系统。该系统提供对应用程序类中成员变量和成员函数的监控功能。研究管理站点和管理代理监控信息的交换和传输方式,包括网络应用软件监控系统协议栈的定义、通讯协议的设计等。阐述监控信息传输时报文分组和重组的必要性,并设计相应的算法。研究结果表明:该网络监控系统可用于实现管理站点和管理代理间监控信息实时、准确的交换与传输。

Communication design between management station and management agent

On the basis of expansion of management information and protocol data unit of simple network management protocol,a net monitor system for application software is designed and implemented.The system plays a monitoring role for the member variable and function of the class in the applying procedure.The mode of exchange and transmission of monitoring information between management station and management agent is studied,including definition of protocol stack,design of communication protocol,ete.When monitoring information transmitted,the necessity of grouping and regrouping of datagram is illustrated,algorithms of grouping and regrouping are designed.The results show that the exact and timely exchange and transmission of monitoring information are attained from management agent to management station.
