The rapid development of Internet makes network management on large-scale network a critical issue. But with the management task of large-scale network becoming more complicated, neither centralized network management nor agent based network management can satisfy the increasing demands. This paper presents a network management framework to support dynamic scheduling decisions. In thisframework, some algorithms are proposed to decompose the whole network management task into several groups of sub-tasks. During the course of decomposition, different priorities are assigned to sub-tasks. Then based on the priorities of these sub-tasks, the strategies of agent scheduling are established. Priority-ranked sub-tasks are grouped according to their inter-dependences. Sub-tasks with the samepriority are put infofhesame group and can be performed in parallel manner, while different groups of sub-tasks with different priorities must be implemented according to the order of their priorities.
