Phone Numbers for telecons
==========================

New Actions
============

[AP] Review/update EGEE demo slides
[AP] Modify NSAP implemetation so that it checks
     reverse bandwidth

[FS] Ask Alberto Di Meglio to create a project in 
     JRA1 repository for L-NSAP implementation

[GV] Send an email raising issues with the L-NSAP spec.

[KK] Add users of BAR to DJRA4.1


Ongoing Actions
===============

[CP] Create a skeleton system test document
    - create a document with basic structure
[CP] Create first draft of TOC for DJRA4.4

[FS/CP] Review GN2-SA3 NSAP WSDL
[FS] Ask AP if "reservable path" in Glue Schema is still
     needed/necessary
      - Find a "home" for this.

[KK] Investigate usage of BSD license in glite software
     - Software using BSD licensed software need not be under BSD
     - Modified version of a BSD licensed software needs to be
       published under the BSD license again
     - Speak to JRA2 (Quality) - Done.
     - Speak to Bob (EGEE technical director)

[KK] Delete "Service Class" from South Interface (NSAP) of DJRA4.1

[AP/MB] Add L-NSAP Interface to DJRA 4.1
     - Send modified version to KK directly
[AP/MB] Update details on L-NSAP in BAR end-to-end specification 
        *after* the MJRA4.7 review.
[AP/MB] Update details on NSAP (and if necessary L-NSAP) in BAR end-to-end 
        specification *after* the MJRA4.7 review.

[GRNet] Deploy and Test NSAP on GRNET
         -> [FS] Help Chrisostomos at the EGEE04 conference

[ALL] Discuss who manages resources -> BAR or L-NSAP ?

      any resource management.

[ALL] Check actions listed in the *DJRA4.4* workplan.
[ALL] Email few line of work plan for the next week to the minute taker.

Prioritised Wish List for DJRA4.4
=================================

Items in the list are prioritised as "MUST", "SHOULD", "MAY" and "NOT IN SCOPE"


MUST
----

1) Resolution of how to distinguish between a SR and SA (via the HLM-BAR interface).
   - include this in WP1.1 (updates to BAR end-2-end spec) and WP1.12 (BAR service design)

2) Description of BAR-L-NSAP interface (model) 
3) BAR SR and SA management
    - Identify who does resource management; is it BAR or L-NSAP
4) Updated JSP client which support SR and SA


SHOULD
------

1) Development of dummy L-NSAP
2) A separate interface for BAR-BAR (east-west)
   communication
3) Identify a user for SR


MAY
---

1) Validate HLM requests based on local BAR configuration.
2) BAR-NSAP security
3) Integrate NRS to L-NSAP
4) Evaluating EGEE Agreement interface
5) Further investigation of gLite Service Discovery


NOT IN SCOPE
------------

1) BAR-BAR security
2) BAR-L-NSAP security
3) HLM-BAR user authentication


Issues/bugs for DJRA4.4
=======================

 1) How should we change BAR WSDL to reflect SR and SA ?  
 3) Can we match a SA to SR without HLM having to be aware of the SR (e.g., without
    having to use SR IDs ?
    - If so, how do we ensure that the user is allowed to make this SA for a specific SR?
      (or a SR ID is required per SA request?

--------------------------

 2) Will it be possible to re-use the BAR WSDL for North and East interface ? 
    - Yes, FS is already doing this.

      2005-Jun-28 13:42 fscharin fscharin
    - FS says no further refactroing is necessary

#10413 Why do we have RequestService:TimeForAverage parameter in
 HLM-BAR interface?  2005-Aug-22 17:24 apatil charaka
    - close with the resolution -> For future use
