摘　　要：大数据云计算时代,联合光网络资源和数据中心资源的虚拟基础设施规划是解决光网络所面临挑战的最佳方法。建立了带波长转换能力和不带波长转换能力的两种虚拟基础设施规划的整数线性规划模型。采用动态业务请求,以最小联合能耗和最小网络资源使用率为目标函数,仿真比较了两种整数线性规划模型的能耗和阻塞率性能。结果表明,在轻负载情况下,最小联合能耗具有较低的能耗;在重负载情况下,最小网络资源使用率具有较低的能耗;而最小网络资源使用率始终具有较低的阻塞率。In the era of big data and cloud computing, the virtual infrastructure planning converged optical network resources and data center resources is the best way to solve the challenges facing optical networks. Two integer linear program models for virtual infrastructure planning are established with and without wavelength conversion capability.With dynamic service request, two objective functions of the two models： minimum joint power consumption and minimum network resource utilization rate, are simulated and compared with the power consumption and the blocking rate performance. The results show that, under light load conditions, the minimum joint power consumption has lower power consumption; under heavy loads, the minimum network resource utilization rate has lower power consumption; the minimum network resource utilization rate always has a lower blocking rate.
