A Flexible Network and Compute-Aware Orchestrator to Enhance QoS in NFV-Based Multimedia Services

摘要

People and organizations around the globe are using multimedia applications to communicate. By evolving their networks, network operators are taking advantage of the convergence of voice and data. QoS metrics are usually based on parameters from the user side or network side. In this context, NFV and SDN can improve the communication experience and offers an abstraction layer to the deployment of flexible multimedia applications provided on the cloud. In this work, we propose an approach to mitigate globally manage network and computing resources for multimedia applications. To this end, we come up with a control plane entity capable of orchestrating compute and network resources for the multimedia application scenario, relying on SIP control messages. Our solution brings QoS enhancement to the user through resiliency, load balancing, packet inspection, scaling on demand and the separation of control and data planes.
