—This paper addresses the problem of managing highly dynamic network and service environments, where virtual nodes and virtual links are created and destroyed depending on traffic volumes, service requests, or high-level goals such as reduction in energy consumption. This problem will be one of the main technical challenges to be faced in the evolution(More)
—Technology advances are making available huge amounts of processing, storage, networking capabilities at the edge (i.e., up to End-Users premises) of current networks. It is argued that these trends, coupled with new emerging paradigms such as Software Defined Networks, will impact deeply the evolution of future networks, allowing to design highly flexible(More)
—This paper presents a new method for selection between replicated servers distributed over a wide area, allowing application and network providers to trade-off costs with quality-of-service for their users. First, we create a novel utility framework that factors in quality of service metrics. Then we design a polynomial optimization algorithm to allocate(More)
