Resumen:
Advances in network technology will provide access to new generation, fully-interactive and client-oriented services such as the Video-on-Demand (VoD). Through these services, users will be able to down-stream video data from remote sites at any time on-demand. During a streaming session, VoD servers provide a continuous visualization of multimedia content, guaranteeing QoS (Quality of Service) levels. VoD services are proving critical for education, entertainment, business, and video-conference proposals. Streaming Video-on-Demand over the Internet is the next major step in the evolution of media content delivery. The global extension of the Internet network makes this environment very attractive for providing VoD services to millions of potential clients. In order to provide Internet VoD services that accommodate a huge number of concurrent users, the design of Large-Scale Video-on-Demand systems (LVoD) is required. The development of these systems requires a highly scalable, fault-tolerant and reliable LVoD architecture capable of providing high performance with limited costs. Nowadays the main alternative that has emerged for deploying VoD services on the Internet is the utilization of the peer-to-peer (P2P) paradigm. A P2P streaming architecture can offer better streaming capacity than conventional server-based architectures, bringing clients' computational and storage resources into the system, hence reducing the workload placed on the server and thereby increasing the overall system scalability. However, the Internet environment imposes further restrictions on P2P streaming schemes in order to provide VoD service. Problems such as quality of service (QoS) support, packet loss, limited bandwidth over peer resources, different Internet Service Providers' (ISP) technology support and content copyright protection are examples of Internet restrictions. This thesis proposes a new dynamic Peer-to-Peer VoD system in the Internet environment, called DynaPeer. Dyna
