QoE-aware dynamic virtual network resource adaptation for EaaS environment

Nowadays, the multimedia content accessed by users represents 55% of the Internet traffic and it is forecast to expand to 92% by 2020. This fact increased the resource demand in access networks across the world, since multimedia traffic has high network requirements. To deal with this scenario, Internet Service Providers (ISPs) tend to apply the Edge as a Service (EaaS) approach. EaaS aims to use Network Virtualization and Network Programmability to expand the flexibility of access to edge network resources. In this context, this paper presents the Bitrate-Aware Virtual Resources Adjustment (BEAVER) mechanism, which increases the Quality of Experience (QoE) support for multimedia clients in EaaS environments. Experiments using real traffic demonstrate the effectiveness of the proposed mechanism to ensure the user´s QoE.
