Internship Proposal
A New Approach for Self-produced Multimedia Content Replication in a P2P Streaming Network
Context and object:
Thanks to the appearance of multimedia content sharing websites, such as Youtube or dailymotion, we are witnessing a significant increase in the number of self-produced multimedia content posted on the web in the recent years. In addition to the increase of these contents and the number of their access, the quality of these contents is also improving rapidly. Hence, we see an evolution of the self- produced content realm from a shared set of short videos of low to average quality to a host of high- definition contents with durations of up to several tens of minutes. This poses a problem for some service providers who see their Internet inter-domain links (i.e. links connecting them to other providers) heavily congested which penalizes other Internet services. A solution to this problem became though urgently awaited.
One solution to this problem would be to prevent the same content, while viewed repeatedly, to traverse an inter-domain link as many times as it is viewed. Thus, the idea would be to establish a content management system to replicate the most downloaded contents and to access them from their replicas. In order to increase its efficiency, such a content management system can be based on the Peer-to-Peer (P2P) paradigm. The core of such a system is the content replication approach. This approach should depend on various factors, the importance of the content, the remaining storage capacity in the network, and the number of replicas required for the content to name a few. The objective of this internship is, initially, to propose such a content replication approach and validated.
In a second step, the proposed approach should be implemented on a prototype of a P2P content management system. This latter has already been established (during a previous internship) and is available at ENSIIE. Finally, an experimental evaluation of the proposed approach has to be made in order to assess its qualitative and quantitative features.
