This report is about quality of service (QoS) for Video on Demand (VoD) delivered with peer-to-peer (p2p) networks. The focus is on QoS issues due to mismatching between physical and overlay p2p topologies. This mismatching causes undesired traffic load in the network and makes delivery of VoD services with QoS hard. In the report the main architectural and content control design issues are discussed, it is shown how topology mismatching is a common issue of both unstructured and structured p2p approaches, and the main solutions proposed for this issue are reviewed. The aim of this study is providing fundamentals for the design of innovative VoD architectures, signalling and protocol solutions addressing the topology mismatching issue.

Abstract

This report is about quality of service (QoS) for Video on Demand (VoD) delivered with peer-to-peer (p2p) networks. The focus is on QoS issues due to mismatching between physical and overlay p2p topologies. This mismatching causes undesired traffic load in the network and makes delivery of VoD services with QoS hard. In the report the main architectural and content control design issues are discussed, it is shown how topology mismatching is a common issue of both unstructured and structured p2p approaches, and the main solutions proposed for this issue are reviewed. The aim of this study is providing fundamentals for the design of innovative VoD architectures, signalling and protocol solutions addressing the topology mismatching issue.
