Descripció: [ANGLÈS] The consumptions of all forms of Internet video are constantly growing. For example, the collective sum of videos would be accounted for 86% of the global traffic by 2016. As the bandwidth requirement rises, the distribution costs will increase and hence an efficient strategy for supporting video distribution is essential. The distribution mechanisms that aim to be scalable, fault-proof, and cost-efficient, like P2P systems, have therefore become very popular. At present, videos of different qualities are available to ensure that various types of end-user terminals can be supported. Layered coding schemes allow the encoding of content into several qualities within a single stream, providing the viewer with the best quality depending on his needs and capabilities. This project aims to study and optimize the intersection between distributed Peer-to-Peer streaming approaches, centralized systems using Content Delivery Networks (CDN), and layered content using Scalable Video Coding. As a result, we propose a complete system that merges the three technologies and takes benefit from all its advantages. We propose a network organization with low delay and incentives to contribute, defining also an algorithm to reconstruct precedent network topologies and reducing the time to find good peers. A new mechanism has been designed in order to select the scalable layers to download according to the bandwidth available, with more stability and precision than other existing proposals. Finally, we defined the policies of the content to store in the Content Delivery Network, being firsts at taking advantages of both the layered content and the Peer-to-Peer network.
