Akogrimo – Grids + Network operators
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.
Martin Hafner’s talk presented the business modelling framework This talk is mainly about standards

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)

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

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

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
WS-Agreement or WSLA
NextGrid, OntoGrid, UniGrids, and possibly HPC4U
Workflow for Grids NextGrid, UniGrids
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

Thank you

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
15
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
16
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
17
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.
18
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
19
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
20
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
21
Partner experience with standards organisations
GGF+EGA: CCLRC, NTUA, ATOS, USTUTT
W3C: CCLRC
IETF: IT-Aveiro, Telenor, UniZH, USTUTT
ETSI: TID
