摘　　要：在网络虚拟化环境中,需要对底层网络资源状态进行实时监控,合理的监控策略应该尽量减少状态信息上报所需的时延和带宽。为了实现该目标,该文设计了一种基于监控代理的资源监控策略,该策略将监控代理的部署转化为0-1规划问题,并通过改进的量子遗传算法对该问题进行求解。仿真实验表明:该策略生成的监控代理部署方案在降低通信开销方面有着较好的表现。The network virtualization requires real-time monitoring of the substrate network resources state. An efficient monitoring policy should reduce the transmission delay and bandwidth of state information collection. For this objective, a resource monitoring policy based on monitoring agents is designed. This policy formulates the issue of monitoring agents deployment as a 0-1 programming problem, which is solved by the advanced quantum genetic algorithm. Evaluations show that the scheme of monitoring agents deployment framed by the proposed policy has outstanding performance in reducing communication cost.
