  1. Akogrimo & standards Julian Gallop CCLRC Rutherford Appleton Laboratory ETSI Grid Workshop May 2006

  2. About CCLRC • Provider of large scientific experimental facilities in the UK • e.g. neutron source, space science, hosting new synchrotron (Diamond), ….. • UK strategy and focus for international scientific collaboration • 2 main sites: • Rutherford Appleton Laboratory • Daresbury Laboratory

  3. …… and in ICT • UK and Ireland W3C Office • UK partner in ERCIM ( Keith Jeffery, director of IT, CCLRC is ERCIM president since January 2005 ) • Examples of recent initiatives: • Data Curation; e-Publication. • UK e-science: partner in National Grid Service and National Grid Support, HPCX large computing node, data node • EU Grids: • EGEE, … • also • FP5: GRASP • FP6: [ Trustcom, ELEGI, ] CoreGrid, Akogrimo, Xtreemos

  4. Grid services: To be pervasive Anyone, anywhere, any time fixed or mobile personalised knowledge and semantics To allow for: Ad hoc, dynamic and cross-organisational federations and workflows To solve complex scenarios in everyday life For network and service operators: To extend their scope by developing new, business services and value added chains. Akogrimo – Grids + Network operators • Martin Hafner’s talk presented the business modelling framework • This talk is mainly about standards

  5. Akogrimo partners • Network operators: • Telefonica (lead), Telenor, IT-Aveiro • s/w industry: • ATOS, Datamat • Tool Provider: • BOC • Grid Infrastructure providers: • University of Stuttgart, CCLRC • R&D: • Universities of Hohenheim, Zurich and Madrid; • CRMPA and ICCS/NTUA • Plus 2 new partners for 3rd testbed

  6. Akogrimo Standardisation Environment • The Akogrimo standardisation environment (among others) • European Telecommunications Standards Institute (ETSI)  Strategy for Grids standardisation • Global Grid Forum (GGF)  OGSA, Grid Resource Allocation Agreement Protocol (GRAAP), Grid Economic Services Architecture Group, Telecommunication Community Group (TELCO-CG) • Internet Engineering Task Force (IETF)  A4C, Policy, Session Initiation • World Wide Web Consortium (W3C)  XML, WS, OWL • Resources • Technical work in support of standardisation • Dissemination of potential areas of standardisation • Coordination of standardisation activities • Representation on EU Grid collaboration group (GCSG)

  7. Standards in Akogrimo An incomplete list of standards used, by organisation • GGF: OGSA, WS-Agreement, • OASIS: BPEL, SAML, UDDI, WS-N, WSRF • WS-* industry: WS-Agreement, WS-Policy, WS-Security • W3C: OWL, SOAP, WSDL • OMA: MLP, WAP-UAPROF • IETF: AAA, DIAMETER, COPS, EAP, MIPv6, PANA, PIDF & RPID, RSVP, RTP, SDP, SIP

  8. Standardisation Efforts Planned • Topics • Integration of network services into a Grid framework  GGF+EGA • Mobile Grid use case  GGF+EGA • Extending presence to include context  IETF • Interpretation and mapping of context in a Grid environment  tbd • Accounting parameters to support a mobile Grid  IETF • OGSA resource usage recording in a mobile context  GGF+EGA • SLAs for mobile Grid services  GGF+EGA • Role of ETSI vis a vis GGF+EGA or IETF? • Further involvement: Telecommunications CG (Community Group) (GGF) • Within the Project: • Resources for standardisation not large • Prior experience of standardisation not large

  9. EU GSCG • Grid Standards Coordination Group • Philipp Wieder (NextGrid) and Julian Gallop (Akogrimo) are co-chairs • Task is to increase the effectiveness of standardization efforts of EU FP6 Grids Projects (benefitting from FP5 experience) • Started with 12 EU Projects in FP6; further FP6 projects starting imminently • White paper: • Identifies common interests – e.g. several Projects may be able to contribute to a particular standard • Akogrimo slightly different emphasis because of interest in integration of all network layers

  10. EU GSCG - examples

  11. Some issues • Respective roles of GGF+EGA, IETF, W3C, ETSI in Grids Standards • For those involved with GGF+EGA or W3C, how does ETSI change the picture • Essential not to increase number of competing standards, but to make better decisions • For any new Grid specification, need to understand who should manage the process and who should add further value • Cooperation with EU GSCG (Grids Standards Collaboration Group) • Clear Akogrimo interest in cross layer issues

  12. Thank you

  13. EU Grids collaboration • Standardisation is one of the EU Grids collaboration activities • With NextGrid, started EU Grid Standards Co-ordination Group (GCSG) and the other FP6 Grids Unit Projects (12 in the 1st wave) • Identifying common areas of interest to increase effectiveness in future • Delivered collaborative report (NextGrid deliverable) • Some common topics noted later

  14. Key standards topics for influence • Identify areas to focus Akogrimo influence • Build out of experience in 1st cycle. Need to make use of: • Visible Akogrimo added value • Experience in consortium • You may observe a correspondence from the emerging Akogrimo inventions list (Exploitation presentation) • Main topics • Integration of network services into a Grid environment • Mobile Grid use case • Presence and context • Accounting • Service Level Agreement • We discuss these topics one per slide • Depending on work in 2nd cycle, we do not exclude the possibility of further topics e.g. security and/or identity

  15. Network services in a Grid framework • Purpose: • In a Grid environment, need to be able to invoke, monitor, manage network services • e.g. SIP call in architecture • Network services being considered: • Nothing to do: MIP, RSVP • In Daidolos: FMIP • Potential: COPS, SIP, SDP

  16. Mobile Grid use case • Purpose: • In GGF, use cases are influential • A Mobile Grid Use case can describe selected key points from Akogrimo scenarios • GGF+EGA (which will merge Summer 2006) appropriate forum. OGSA not in a use case phase at present. Investigation of other GGF+EGA groups. • Telecomms Community Group in GGF – NTUA spoke at GGF16.

  17. Presence and context • (1) RPID • Extend presence to more general description of context • (2) Context interpretation • Context needs to be appropriate for Grid applications • RPID = Rich Presence Extensions to PIDF

  18. Accounting parameters to support Grids • Purpose: • Standard methods for AAA crucial in Grid environment – diverse and changing providers. Need well-defined set of accounting parameters. • Notes • At this level, IETF Diameter extensions • Need translation to OGSA accounting

  19. SLA • Purpose: • Mobile Grids introduce service level problems not experienced by fixed Grids • WS-Agreement or WS-AgreementNegotiation (which is at an early stage) • Common interest with TrustCOM

  20. Partner experience with standards organisations • GGF+EGA: CCLRC, NTUA, ATOS, USTUTT • W3C: CCLRC • IETF: IT-Aveiro, Telenor, UniZH, USTUTT • ETSI: TID • IRTF: IT-Aveiro
