Research on general adaptive management mechanism of active network

This paper studies a general QoS adaptive management mechanism in view of video server and active node. For the video server, we put forward an idea of video period task set as well as defining some video services with this set. This paper also designs a kind of mixed real time task scheduling arithmetic which taking QoS critical level as a character of task priority vector to build video period task set and accomplish dynamic resource management, based on QoS conveniently. Therefore, it realizes the service quality control of small granularity. Based on it, the paper further puts forward active node adaptive QoS control component. Through designing dynamic resource trading active queue and using mixed priority of video active packet, the new idea not only makes system support video application as much as possible, but also enables it to satisfy resource trading requirements of user. At last, a simulation experiment is carried out to illustrate the advantage of active queues after amelioration.
