Bandwidth Allocation and Reservation JRA4
Anand Patil, Maarten Büchli (DANTE)
EGEE-JRA4 meeting, CERN, 14/15th October 2004
www.eu-egee.org
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 2
Outline
• Status of DJRA 4.1
• Future steps
• Collaboration with JRA 1
• Architecture discussion
• Interface discussion
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 3
Status of DJRA4.1
• Requirements based upon SA2 working document
• Clear demarcation between EGEE and GN2 projects
• Focus on interface specification First iteration Requires further refinement
• Initial architecture discussions with JRA1 were held
• Comprehensive software survey presented as an addendum
• Submitted for review on time – 30th Sept. 2004
• No review comments on deliverable received yet
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 4
Future steps
• Finalise architecture and interfaces• Extract reusable components from surveyed software• Collaborate with other activities• SA2
monitor the requirements working document
• JRA1 more later
• JRA3 security issues
• GN2 –SA3 continue discussions on interface between EGEE and GN2
• Start developing prototype
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 5
Collaboration with JRA1
• Understand Web Services Agreement (WS-A) framework
• Monitor JRA1’s WS-A architecture working document
• Achieve a common and realistic understanding of network element (NE) functionality
• Can NE be seen as another element such as the storage element or computing element?
• Organise meetings/conference calls for detailed discussions with JRA1
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 6
Architecture discussion
EGEE JRA4 BAR workshop, Cambridge, 8 September 2004 - 7
Interface discussion
• Interface between higher layer middleware and network element
• Interface between network element and network service access point
• Deliverable contains first iteration of interface specification Interfaces will be refined during prototyping
• A field by field discussion is required!
