EGEE JRA4 meeting, CERN, 16 June

6. Criteria for Analysis
Criteria for the analysis of the selected software has been agreed upon
Document outline has been created
Template has been made to structure the analysis of each software package and its associated interfaces
Improves readability of the document
Easier to compare different software packages and interfaces
This is available on EDMS
EGEE JRA4 meeting, CERN, 16 June

7. Current Status Study of software and interfaces has started
Draft texts have been written and circulated
Individual contributions to be submitted by the end of June
All text will be merged into the final document
Some editing work on the final document
Deliverable to be ready for review by the second half of July
Need to identify internal and external reviewers
EGEE JRA4 meeting, CERN, 16 June

8. Architecture for bandwidth allocation
and reservation
EGEE JRA4 meeting, CERN, 16 June

9. Bandwidth Allocation Architecture
Initial team for defining architecture identified
Draft architecture diagrams circulated
Preliminary discussions on the EGEE bandwidth allocation architecture
Administrative control
Development responsibility
Identified overlap with GN2-SA3
Need to cooperate with GN2-SA3 team
EGEE JRA4 meeting, CERN, 16 June

10. Cooperation with GN2-SA3
Overlap in the objectives of the two activities
Face to face meeting held at Dante office (6th May 2004)
Cooperation between EGEE-JRA4 and GN2-SA3
Discussion on a boundary between EGEE-JRA4 and GN2-SA3
GN2-SA3 has non-grid clients
Avoid duplication of effort
Reduce dependency on each other
Software to follow Web Services architecture
Cooperation with GGF-GHPN
With input from some discussions a draft version of the architecture and interfaces document has been created
Available at:
