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

EU GSCG - examples

WS-Agreement or WSLA

NextGrid, OntoGrid, UniGrids, and possibly HPC4U

Workflow for Grids NextGrid, UniGrids

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
