To further enhance networking among participants, QoMEX 2009 has
created a number of social networks accessible from its website at http://www.qomex.org
. We would like to invite you to access them today, and get involved
in one or more of these social networks by introducing yourself,
presenting your interests, your ideas, results of your research in
various multimedia forms, giving your opinion and impressions,
exchanging all sorts of relevant information, asking questions,
providing answers, and in short, becoming an active members of the
growing community of Quality of Multimedia Experience. We look forward
to meeting you in our social networks even before seeing you in person
in San Diego.

Other updates on the website:
- Welcome Note from the co-chairs posted.
- Presentation preparation instructions, including the poster board
size have been added to the Paper Kit.
- The technical program schedule is now posted.

P2P'08: Last day, the day after the social event...

Today, I'd like to report from the last day of P2P'08 (a.k.a. the day after the social event; follow me on twitter for some details) and also give some highlights from yesterday's keynote, industry session, and so on.

Yesterday's keynote from Anja Feldmann (Deutsche Telekom Laboratories) was about the relationship between ISPs and P2P, i.e., challenges and opportunities. In particular, there needs to be information exchanged between ISPs and P2P system which is a huge issue. In fact, the ISP does not want to provide information about their topology which would help to increase the performance of the P2P system. However, she proposed a compromise in a way that the P2P system shall provide a list of destination IPs (i.e., other peers to which a peer may connect) and the ISP returns a ranked list of destination IPs based on their topology. In this way locality is provided during peer selection without exposing the ISP's infrastructure details. Some people say that this might face scalability/complexity issues as such a query might easily include thousands of IPs. A paper about this can be found here.

From the industry session I'd like to pick up two talks and briefly summarize them. The first from Martin Stiemerling (NEC), "A Peer-to-Peer SIP System based on Service-Aware Transport Overlays", with the goal to provide a generic P2P and transport overlay system that is not bound to a certain usage (e.g., files, voice, video). In that sense the developed a Service-aware Adaptive Transport Overlay (SATO) which includes dynamic adaptation to changes (network, context). However, they only focus on voice and for IPTV it is a complexity issue of transcoding thousands of streams in parallel (no SVC used). This work has been done in the context of the Ambient Networks project. The second talk I'd like to mention was from Victor Souza (Ericsson) about "P2P traffic in ISP Network" that had a strong relationship to the keynote (see above). For live streaming they propose a time shift mechanism comprising content ingestion, content migration, content lookup, and content download. They have a prototype out there that allows for both VoD and live streaming. Furthermore, they propose to place media caches near the customer. However, there were strong doubts that this will be possible. Anyway, it is interestin to see that others have similar problems as we have and how they're trying to solve them.

Traditionally, P2P is about file sharing and has been extended to games, voice, audio, video (VoD, Live Streaming, IPTV) applications' space. At P2P'08 I've discovered some further application areas:

• P2P-based file system: IGOR File System, "The IGOR File System Demonstration" (Bernhard Amann, Benedikt Elser, Yaser Houri, Thomas Fuhrmann)
• P2P-based Wiki engine: Piki - A Peer-to-Peer based Wiki Engine (Patrick Mukherjee, Christof Leng, Andy Schürr)
• P2P-based power control system: "Towards P2P Technologies for the Control of Electrical Power Systems" (Kolja Eger, Christoph Gerdes, Sebnem Öztunali)

… it seems that becoming "P2P-based" becomes the (new) trend ;-)

Next year, the conference will take place in Seattle.
