1. RINGrid project use case survey
RISGE-RG meeting
Ischia, Italy /
Costas Kotsokalis, GRNET
on behalf of RINGrid consortium

2. RINGrid information EU design study
What are the requirements for integrating instruments with the Grid?
Use case survey
Experimental activities
Ended up with a model use case and (what we tried to be) OGSA-relevant recommendations

3. Questionnaire Challenge: Make it domain-independent
Information solicited
Correspondent details: Name, , education, discipline, level of expertise
Type of instrument
Summary of experiment & Duration info
Exclusive access indicator
Known technical limitations
Steps of the experiment

11. Recommendations (1) Network-level
QoS provisioning: VPNs, BoD, cross-domain traffic engineering
Wide IPv6 use
Assess access-networks transfer capability
Emphasis on satelite links

12. Recommendations (2) QoS provisioning on the service level
An appropriate service definition implementing instrument functional and manageability interfaces (the “BES” of instruments)
Inclusion of instrument resources in information models such as GLUE
Suggested topics for further investigation
Relation between digital libraries and experimental data
Ontologies and semantic web concepts for the description of instruments
