Analytical Modelling of Localized P2P Streaming Systems under NAT Consideration
نویسنده
چکیده
NAT has been design to work with Internet client-server structure. The emerged of Peer-to-Peer (P2P) networks and applications revealed the incompatibility between P2P applications and NAT. Many methods has been developed and implemented to solve connectivity between peers behind NAT devices. Nevertheless, various NATing types can’t communicate with one another. In this work, we are going to study the impact of NAT types on the start-up delay time of peers in P2P streaming systems. We will demonstrate the ability of NATing to expel peers in P2P live streaming systems. A new neighbour selecting algorithm will be proposed. This algorithm will utilize NAT-types configurations as a parameter. We have utilized NS2 simulator to show the performance of the new algorithm in increasing the connectivity, reducing the number of expelled peers and implementing of locality.

Distributed Optimization of P2P Media Delivery Overlays
Media streaming over the Internet is becoming increasingly popular. Currently, most media is delivered using global content-delivery networks, providing a scalable and robust client-server model. However, content delivery infrastructures are expensive. One approach to reduce the cost of media delivery is to use peer-to-peer (P2P) overlay networks, where nodes share responsibility for delivering...
متن کاملCharacterizing Locality-aware P2P Streaming
Peer-to-peer (P2P) live streaming systems have been increasingly popular and successful in today’s Internet, which provide large collections of video channels to millions of users at low server costs. The large volumes of P2P streaming traffic are exceeding those incurred by BitTorrent-like file sharing applications, threatening huge traffic relay cost to the Internet service providers (ISPs). ...
متن کاملDistributed Peer Discovery in Large-Scale P2P Streaming Systems : Addressing Practical Problems of P2P Deployments on the Open Internet
Peer-to-peer (P2P) techniques allow users with limited resources to distribute content to a potentially large audience by turning passive clients into peers. Peers can self-organize to distribute content to each other, increasing the scalability of the system and decreasing the publisher’s costs, compared to a publisher distributing the data himself using a content delivery network (CDN) or his...
متن کاملRobust video-on-demand streaming in peer-to-peer environments
This paper presents a new video-on-demand streaming technique in peer-to-peer (P2P) environments. While a number of P2P live video streaming techniques have been proposed in the past, we argue that the two types of video streaming, live and on-demand, have some subtle differences. Most notably, a P2P video-on-demand streaming technique has to handle the asynchronous arrival of peers efficiently...
متن کاملAnalytical Framework for Streaming over TCP
Multimedia streaming applications are traditionally delivered over UDP. Recent measurements show that more and more multimedia streaming data are over TCP as web-based TV, P2P streaming, video sharing websites are getting increasingly popular. To improve the Quality of Experience (QoE) for users and to cope with variability in TCP throughput, streaming applications typically implement buffers. ...
