Towards a Multi-tier Fog/Cloud Architecture for Video Streaming

The video streaming services are already responsible for the majority of the Internet traffic. A good cloud-level architecture partially solves some issues related to the video streaming services. However, it introduces other issues such as higher latency and core network congestion, addressed in this work: we propose a multi-tier architecture composed of a set of services to video streaming in a fog computing environment taking into consideration classified hierarchical tiers and the ETSI-NFV architecture. The main goal is to design and assess a reliable, high-quality multi-tier services architecture to be used in Smart City environments. To this end, we introduce a set of video streaming services in the fog-cloud infrastructure, and also discuss how these services may be used to improve the Quality of Experience (QoE) for end-users.
