New advanced techniques must be developed to support the growth of IPTV services and to boost quality delivered to the consumers. Optimization technique is proposed for the way users access video content delivered via wide area networks. The perceived quality of service will increase because the user accesses video content temporarily stored in nearby geographic locations. Temporary storage for content...
In this paper we propose new strategies for computing virtual geometric node coordinates in peer-to-peer overlays. The main goal is to obtain a decentralized network where each peer has a set of (multidimensional) coordinates and the distance between two peers is proportional to the round-trip time (RTT) between the peers. We consider methods based on the Euclidean distance and the Linfinity norm...
As the infrastructure-centric model of peer-to-peer streaming, recent overlay construction schemes compose a hierarchical topology of peers by grouping them into clusters. There is a server in each cluster that receives data from the source and relays it to its cluster members. In this paper, we propose an alternative infrastructure-centric peer-to-peer framework called BAHMO that constructs a hierarchical...
We consider a server that simultaneously streams multiple video channels. Each video channel is delivered to a set of receivers using peer-to-peer (P2P) live multicast. We propose a framework for allocating server bandwidth to minimize distortion across the peer population, across all channels. The optimization problem considers rate, distortion, the audience size, and peer-churn associated with each...
We present CPM, a unified approach that exploits server multicast, assisted by peer downloads, to provide efficient video-on-demand (VoD) in a service provider environment. We describe our architecture and show how CPM is designed to dynamically adapt to a wide range of situations including highly different peer-upload bandwidths, content popularity, user request arrival patterns, video library size,...
IP multicast is considered a core requirement for IPTV network architecture. In this paper, we argue that challenges associated with deploying and operating IP multicast networks is one of the reasons why smaller or medium-size service providers cannot offer IPTV services. We explore peer-to-peer streaming as an alternative to IP multicast and argue that for congested urban areas it may be a superior...
This paper presents an algorithm for creating and maintaining a dynamic localized peer-to-peer overlay network with its main application to massively multiplayer games. In these games, players reside in a large game world with many thousands of players but each player has typically a limited vision range. In our solution, players join the network as peers and mainly connect to neighbor peers that...
