Redes de Distribuição de Conteúdos: Integração com IPTV e Estudo sobre Codificação de Rede

26/10/2007

The Internet has experienced a strong growth over the last years. However, the available bandwidth remains over occupied due to its intense global usage and the increasing volume of contents with high resource consumption. The Content Distribution Networks (CDNs) are an efficient approach to improve the quality of service in the Internet by replicating contents from their original locales to servers as near from the users as possible. This dissertation has CDNs as its central subject of discussion. It comprises three core chapters: description of how a CDN operates and which are the main challenges regarding the design of an efficient CDN; analysis of a practical application of a centralized CDN to a commercial system; study of Network Coding as a strategy to improve the dissemination of contents over peer-to-peer CDNs such as BitTorrent.
