A method of optimizing the use of server resources that can reduce the energy costs of a network while preserving service quality parameters is proposed in this paper. This method involves the use of resource involvement schedule based on long-term statistics. Unlike existing methods, proposed method simultaneously considers the losses of requests, expected delay and energy efficiency of processing...
In this paper the main aspects of usage Network Functions Virtualization (NFV) in the domain of Evolved Packet Core (EPC) virtualization are given. Modern virtualization technologies in combination with existing tools for storage and computing, ensure virtualization and abstraction for the entire set of critical resources. The general aim of NFV is to deliver functions, networks and infrastructure...
Dynamic resource provisioning is a useful technique for handling the variations seen in communication systems workloads. In this paper the problems of multiple stage multiple resource multiple service systems are discussed. A dynamic provisioning technique for multi-stage systems that employs a flexible analytical model to determine how much resources to allocate to each stage of the system is presented.
