Minimizing file downloading time in stochastic peer to peer networks

Thesis Overview

<p> </p><p><strong>1.0 INTRODUCTION</strong></p><p>Peer-to-peer (P2P) technology is heavily used for content distribution applications. The early model for content distribution is a centralized one, in which the service provider simply sets up a serve and every user downloads files from it. In this type of network architecture (server-client), many users have to compete for limited resources in terms of bottleneck bandwidth or processing power of a single serve. As a result, each user may receive very poor performance. From a single user perspective, the duration of a download session, or the download time for that individual user is the most often used performance metric.</p><p>P2P technology tries to solve the issue of scalability by making the system distributed. Each computer (peer) in the network can act as both a server and a client at the same time. When a peer complete downloading some files from the network, it can become a server to service other peers in the network. It is obvious that as time goes on, the service capacity of the entire network will increase die to the increase in the number of servicing peers. With this increasing service capacity, theoretical studies have shown that the average download time for each user in the network is much shorter than that of a centralized network architecture in ideal cases (2), (3). In other words, users of a P2P network should enjoy much faster download.</p><p><strong>1.1 STATEMENT OF PROBLEMS</strong></p><p>Owing to:</p><p>i) The difficulties people face in locating a web application workshop.</p><p>Urgent need to contact a web application workshop at emergency time.</p> <br><p></p>
