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. At the same time, however, it introduces new ones such as higher latency and core network congestion. In order to improve on this matter, this work proposes a multi-tier architecture composed of a set of services to video streaming in a fog computing environment. It also takes into consideration classified hierarchical tiers and the ETSI-NFV architecture. The main goal is to design and assess a reliable and high-quality multi-tier services architecture to be used in the Smart City environments. To this end, we introduced a set of video streaming services in the fog/cloud computing, and also proposed how these services may be used to improve the Quality of Experience (QoE) for end-users.
