A Virtualized Application Service for QoS Management

Abstract

IP Multimedia Subsystem (IMS) is a framework that provides multimedia service to standard UMT-based mobile user. The IMS requires the assurance of QoS (Quality of Service) for the network flow between users, but QoS of network resource depends on existing protocol scheme. In recent, the research on reliability and QoS of the multimedia service based on NFV/SDN is claimed for the deployment of 5G network environment. Therefore, the design and analysis of QoS-enabled application service deployment is needed for the accomplishment for resource allocation of network resources. In this paper, we propose the architecture for QoS-enabled application in the environment of Virtualized IMS (V-IMS).
