Nozzilla: A Peer-to-Peer IPTV Distribution Service for an IMS-based NGN


Alex Bikfalvi, Jaime García-Reinoso, Iván Vidal, Francisco Valera


During the last years next generation networks (NGNs) have gained attention, as an increasing number of network operators moved toward triple-play services: telephony, Internet and IPTV. Unfortunately, from the service provider perspective, IPTV usually comes at a high cost in terms of equipment and/or necessary bandwidth. In this paper we propose Nozzilla, a peer-to-peer like video streaming service for an NGN based on the IP multimedia subsystem (IMS), which can be used by third-party IPTV service providers as a cost effective alternative to IP multicast or content distribution networks. The service uses the residential gateways (NGN customer premises equipment) to create a streaming overlay using the remaining or a fixed amount of network bandwidth. Nozzilla takes advantage of the QoS and resource reservation enabled by a NGN to support multiple-description streaming that improves the perceived quality during temporary failures.
