基于可重构测量模型的网络测量任务部署算法

摘要

针对网络有限测量资源与多样化测量需求之间矛盾日趋凸显的问题，该文在可重构的网络测量模型基础上，对网络测量任务部署问题进行建模，并提出一种测量任务部署算法。该算法利用测量构件复用及组合原理，高效利用网络测量资源，从而支持对多样化并发测量任务的部署。仿真实验数据显示，算法在任务部署成功率和任务部署时间性能指标上较GCTS (Task-execution Scheduling schemes based on Graph Coloring)算法均得到显著提高，任务部署成功率不低于90%。%Since the conflict between the limitation of measurement resources and the diversity of measurement requirements becomes more and more serious, this paper models the issue of measurement task deployment and proposes a new deployment algorithm based on the network measurement reconfiguration model. By using the theory of multiple using and composing of measurement components, the proposed algorithm can not only allocate the measurement resources effectively, but also support the concurrent various measurement tasks. The simulation result shows that the performance of the proposed algorithm on success ratio and average waiting time is more excellent than the Task-execution Scheduling schemes based on Graph Coloring (GCTS). The success ration of the proposed algorithm is more than 90%.
