Towards a QoS-oriented migration management approach for virtualized networks

Abstract

Virtualization environments are dynamic and polymorphic, consequently they require complex management for both, physical and virtual elements. This research addresses the need for a management approach that can drive virtual network migration systematically to guarantee the required levels of Quality of Service (QoS) in virtual networks. This paper describes a framework that includes the processes needed to manage QoS in migration scenes. A selection of policies that will help in systematizing QoS-oriented virtual network migration are described as well. Test results are provided with the intention to emphasize the difficulty and need for formal research in this direction.
