Digital Fountains + P2P for Future IPTV Platforms: An Infrastructure Evaluation

Free registration required

Executive Summary

The opportunities laid by the joint use of Peer-To-Peer (P2P) streaming systems and advanced Digital Fountain (DF) codes in the context of Internet Protocol TeleVision (IPTV) platforms have set high expectations for their combined use. P2P streaming strategies, on one hand, have proven to be able to increase the bandwidth efficiency and the consequent scalability of IPTV platforms. DFs, on the other, have found a potential role in improving the bandwidth efficiency and the robustness to high peer churn rates of P2P streaming systems. However, given the complexity of both of such systems and the unexpected possible outputs that may result from their interaction, an effective assessment of their performances requires the design and setup of real world test-beds.
