论文摘要
被动光网（PON）可以通过提供可扩展，成本和能源效率的体系结构来在数据中心中发挥至关重要的作用。本文提出了一个混合整数线性编程（MILP）模型，以优化虚拟机（VM）在基于能源的WDM-TDM AWGR PON基于数据中心体系结构上的放置。在此优化中，考虑到最小化功耗并促进服务器的更有效利用时，VM的使用及其要求会影响数据中心中使用的最佳服务器数量。检查了两个具有不同计算和网络要求的VM的功耗最小化目标。结果表明，与处理功耗的最小化相比，考虑到WDM-TDM AWGR PON中VM分配的处理和网络消耗最小化可以将网络消耗降低高达70％。
Passive optical networks (PON) can play a vital role in data centres and access fog solutions by providing scalable, cost and energy efficient architectures. This paper proposes a Mixed Integer Linear Programming (MILP) model to optimize the placement of virtual machines (VMs) over an energy efficient WDM-TDM AWGR PON based data centre architecture. In this optimization, the use of VMs and their requirements affect the optimum number of servers utilized in the data centre when minimizing the power consumption and enabling more efficient utilization of servers is considered. Two power consumption minimization objectives were examined for up to 20 VMs with different computing and networking requirements. The results indicate that considering the minimization of the processing and networking power consumption in the allocation of VMs in the WDM-TDM AWGR PON can reduce the networking power consumption by up to 70% compared to the minimization of the processing power consumption.
