Enabling Global Multimedia Distributed Services based on Hierarchical DHT Overlay Networks

1st IEEE International Workshop on Future Multimedia Networking - FMN´08, 16th-19th September 2008, (Cardiff, Wales, United Kingdom)The provision of innovating multimedia services is a high priority for service providers. Due to the the high traffic volume characteristics of multimedia content, decentralised services are a desired solution for multimedia scenarios. Based on the ongoing work of the IETF P2PSIP WG this paper defines a simple way to interconnect different domains using on peer-to-peer technology. The objective is to provide connectivity between users of different domains and allow decentralised multimedia services to be placed where they can be provided most effectively. Furthermore, the routing performance and routing state is analysed for the proposed hierarchical DHT overlay architecture.This work has been supported by the European Union under the IST Content NoE (FP6-2006-IST-038423), by the Regional Government of Madrid under the BioGridNet project (CAM, S-0505/TIC-0101) and by the Ministry of Science and Innovation under the CONPARTE project (MEC, TEC2007-67966-03-03/TCM).En prens
