Design and implementation of monitor message transmission in net monitor system for application software

On the basis of expansion of management information base and protocol data unit of simple network management protocol, a net monitor system for application software was designed and implemented. The system played 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 among management station, management agent and monitor module was studied, including definition of protocol stack, design of communication protocol, etc. When monitoring information transmitted, the necessity of grouping and regrouping of datagram was illustrated, algorithms of grouping and regrouping were designed, and a kind of efficient reversible conversion rule was put forward and contrasted with traditional rules. The results show that the exact and timely exchange and transmission of monitoring information are attained from monitor module to management agent, then to management station.
