P2P Area Meeting Andrew Chien and Cees DeLaat Global Grid Forum 8 June 27, 2003

Agenda Agenda Comments Welcome, Introductions (5) WG/RG Updates (5 each) P2P Area and Stimulating new Activities (15-20) Ubiquitous Computing Group (15)

Group Updates OGSA P2P (Karan B.) Appliance Aggregation (Dejan M.)

Emerging P2P Area Focus P2P technology developing rapidly –Increasingly Important Distinct Space –Capabilities –Devices (small, desktops) => Increasingly well defined vs. OGSA focus

P2P Emerging Focus Minimum reqs to be on Grid (service) –Network connectivity, compute, storage, software infrastructure, PKI P2P distinctions –Networking variable IP, mobility Intermittent connection, availability –IPv6: does it happen here first? Impact? –Service description, Advertisement, Discovery and routing across Naming discontinuities (NAT/Firewall) Multi-hop: indirect communication –Resource volatility and capabilities (compute, memory, energy, etc.) –Extreme Scale (millions? To billions?) Application of emerging P2P Research Technology to support –Extreme Ease of use and configuration/management overhead) Self Healing, Self Tuning Little or no root/centralized control Ad Hoc –Distinct Applications –Others?

P2P Area Opportunities Smallest possible OGSA implementation? Extreme Scalability? Robustness to poor resource availability? Ties to DHTs? Gossip protocols? Others?

Increasing Activities and Synergies Welcome proposals for new technical activities –From existing RGs –From other sources Stimulate ties to academic P2P community –Invite participation; Invited Talks Increase GGF interest in P2P –Proposed Workshop on Relating P2P and Grids (for GGF9) Document relating the two IRTF P2P Area Outreach to IPTPS Others?
