主动网络资源动态协商机制的研究

Research on Active Network Resource Dynamic Trading Model

从通信服务集和安全性这两个关键角度探讨了主动网络中采用资源动态协商机制的重要性。在此基础上建立了主动队列模型作为资源协商之地;同时设计了资源分配算法和资源价格凸函数,让用户直接参与资源协商,自主地共享节点资源。通过OPNET进行仿真实验,实验中设计了资源动态协商和非协商两种方案,从队列长度、包延迟等方面说明了前者的优势。

From perspectives of communication server set and safety, this paper comprehensively analyzes the essentiality for which the resource dynamic trading scheme is applied to active network. Furthermore, this paper puts forward active queue model used as an area for resources dynamic trading in active node, designs resources distribution arithmetic and price function of resources, and lets resources to be shared according to user preferences. At last, a simulation witch used to test the traits of our mechanism such as length of queue, and packet delay time is made under OPNET circumstance. This simulation results indicate that the application makes effective use of the available resources.
