Cloud service providers use replication across geographically distributed data centers to improve end-to-end performance as well as to offer high reliability under failures. Content replication often involves the transfer of huge data sets over the wide area network and demands high backbone transport capacity. In this paper, we discuss how a(More)
As the number of wireless users and per-user bandwidth demands continue to increase, both the vendor and carrier communities agree that wireless networks must evolve toward more dense deployments. So-called " heterogeneous networks " are a commonly proposed evolution, whereby existing macro-cellular networks are supplemented with an underlay of small cells.(More)
Communications technology has great potential for helping other industries reduce their greenhouse gas emissions. Nevertheless, given the relentless growth of demand for communications services, telecommunications providers will need to transition to more energy-efficient technology in order to limit their own environmental footprint. Here we focus on(More)
—The advent of colorless and non-directional recon-figurable optical-add-drop multiplexers (ROADMs) will enable flexible pre-deployment of optoelectronic regenerators in future optical networks. Compared to the current practice of installing regenerators only when a circuit needs them, pre-deployment will allow service providers to achieve rapid(More)
