2.1.4 ElasticTree 由于数据中心流量的突发性,Heller 等人认为,FatTree 为所有的端主机之间提供完全带宽(full bandwidth) 是没有必要的,并从节能的角度出发提出了ElasticTree [22] .其主要出发点是:关掉不用的链路和交换机,仅在需要 时才开启.

Limit Full bandwidth performance may not be achieved with more than one adapter per PCI Host Bridge (PHB) or more than one CPU.
限制全带宽性能可能无法实现一个以上的PCI主机适配器每大桥基丁酸酯(PHB)或一个以上的CPU。
Combined with excellent dc resistance stability, the shunts can be used to directly measure current through their full bandwidth.
加上出色的直流电阻稳定,分流可用于直接测量电流通过他们的全部带宽。
Certainly, one of the biggest enablers will be the full roll-out of 4g technology, which will help with issues of latency and bandwidth.
当然最大的使能因素将是4g技术的全面推出,这将帮助解决延迟和带宽的问题。
