特点是:1)利用光流量整合(optical traffic grooming)技术,减少转发器(transponders)的能耗;2)根据剩余计算资源和节点的度,计算本地资源容量(local resource capacity),映射虚拟节点到物理节点,从而减少激活的物理节点数量,达到降低能耗的目标。

特点是:1)他们假设对于固定的虚拟请求,CPU的能耗是常量(这里有疑问);2)根据虚拟请求量和路径距离,动态调整调制模式,以节约能耗(理由:转发器和再生器(transponders and regenerators)可以调整调制模式,频谱利用率与调制模式和路径的跳数紧密相关,多种调制格式能够影响能耗和频谱消耗,能耗与频谱利用率是一种折中关系,调制模式越大,传输带宽越大,能耗越高);

特点:1)Spectrum-selective sub-channel regenerators (SSRs),Virtualized sub-multi-flow-transponders (VS-MF-OPTs),这些组件与调制模式相关,建立最小化ILP模型;2)设计启发式算法。
