Minutes of Peer-to-peer SIP ad-hoc meeting at IETF 63 Organized by the SIPPING WG Minutes edited by Gonzalo Camarillo Based on notes by Cullen Jennings Meeting chaired by Henning Schulzrinne Slides presented included in the proceedings THURSDAY, August 4, 2005, 0900-1000 There were around 125 attendees. The goal of this ad-hoc meeting was to discuss developing scenarios where p2p technologies may be used. These scenarios include: 1. Distributed Location Server: Use a distributed P2P system to distribute the register/location server information 2. Configuration Storage: Store configuration details for a phone across the networks 3. Voice Mail: 4. Address Book Storage 5. Reputation Systems 6. Gateway 7. Media Relay 8. Media Anonymization People showed interest in working on the following topics: 1. Scale: Both scaling up and down 2. Reliability 3. Federations 4. Trust Models 5. Identity 6. Namespaces 7. Data Storage All the systems described had somewhat common approaches in that they were using DHTs as the underlying approach. Attention should be paid to when it is the right time to use P2P technology and when other approaches such as DNS and Multicast can provide a better solution. It was commented that we should publish some of this before it all gets patented. When it comes to finding an arrangement to work on these issues in the IETF, folks may want to look at what the HIP (Host Identity Protocol) community did. The also had long and short-term goals and they formed an IETF WG and an IRTF RG at the same time. The feeling was that this work would not overlap with the work being done in the p2prg at this point. People suggested to have a full-day meeting right before the next IETF to discuss this work in depth. The meeting ended and folks took a half an hour break before the SIPPING session.
