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.)– [email protected]
• Appliance Aggregation (Dejan M.)– [email protected]
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 DHT’s? Gossip protocols?
• Others?
Increasing Activities and Synergies
• Welcome proposals for new technical activities– From existing RG’s– 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?
