Research And Practice Of A Real-time Monitor And Control System Based On Agents

Real-time monitor and control generally refers to taking advantages of software to carry through a synchronous monitor and control for process of a system operation. A real-time monitor and control system researched and practiced in this paper is primarily applied to monitor and control resources such as CPUs, memories, hard disks, system progresses and etc. of many host computer machines. Considering real-time requirements, when a large number of objects are monitored, the amount of information will increase dramatically. If all of the real-time processing for monitor tasks are processed by the back-end servers, it is not only inefficient, but also the real-time performances can not be guaranteed.All the monitor and control objects of host machines had been separately reconstructed into intelligent agents by introduction of Agent techniques in this paper, through an approach of expanding KQML language realizes communications in multi-agents'system and knowledge sharing is processed by combining agents searching for information with agent providing for information.The main research work and innovations of this paper is summarized as the followings:(1)The traditional contract net has been improved and constructed new model. By dividing BW into different levels according to ability domain, to reduce the amount of communication information between MAFIT and bidding workers.(2)In the improved model trust degree, friend degree, active degree and other measurement parameters have been introduced into traditional contract net protocol in this paper in order to improve cooperation qualities and task distribution succeed rate among multi-cooperator. (3) To realize classification for bidding workers and form different capability level areas through calculating the measurement values by referencing history cooperation records of each bidding workers.According to KQML language extensions, the system implements the communication among agents and realize the knowledge sharing. In order to provide a simple and unified way to deal with each other about their respective tasks for the agent through defined KQML messages particular for this real-time monitoring system.(4)The real-time monitoring system which realized the Multi-Agent system verifies performance improvement on contract net. Basing on the performance compared with the original system proved that with a large amount of data and monitored objects, the MAS system acts better real-time processing, higher efficiency.
