Minutes of the BAR telecon ========================== Date: Tue, 07 March 2006 time: 10:00 GMT/ 11:00 CET Venue: CERN Teleconference Phone Numbers for telecons ========================== The conference phone number at CERN is +41-22-767 7000 - ask for EGEE JRA4, the owner's name is Charaka Attended ======== GRNet: Chrysostomos Tziouvaras (CT) GARR: Gloria Vuagnin (GV) DANTE: Anand Patil (AP), Maarten Buchli (MB) EPCC: K Kavoussanakis (KK), Charaka Palansuriya (CP), Florian Scharinger (FS) Apologies: Agenda ====== 1) On going actions 2) WorkPlan (https://edms.cern.ch/document/694134/1) 3) Preparations for the final EGEE-I review in May 06 4) Issues/bugs 5) AOB 6) DONM New Actions ----------- [CP] Estimate effort for GridNets paper, and add task to WP [FS] Raise Savannah issue WP2.9a "Map L-NSAP failure message" [FS] Check Savannah issue #14082 Ongoing Actions --------------- [FS] Add GDFT Reservation issue to the "difference between architecture vs implementation" appendix of MJRA4.5 [FS] Add section "Service Discovery" to e2e Document - low priority [CP] Fix Savannah issue #14256 - Bandwidth Reverse rounding off issue when Bandwidth Forward is small - Added more unit tests to test bandwidth explicitly [AP] Review Florian's doc about differences between BAR architecture and implementation: - is now in appendix of MJRA4.5: https://edms.cern.ch/document/593453/2 [KK] Send Email to AP on how e2e testing environment (involved parties) could be done (e.g. for review) [ALL] Email few lines of work plan for the next week to the minute taker. Completed Actions ----------------- [CT] Check capacity reserved for PIP in GRNet - Talked to Greek team, will clear AMPS DB today - Was able to to 1 and 10 GBit reservations [FS] Fix cancel handling to support two-phase cancellation of NSAP [FS] Add diagram of AMPS cloud to Test Plan document as soon as final version of diagram is available [FS] Update BAR WSDL's Query Response part so that the additional messages from network services can be displayed [FS] Add to a BAR end2end spec (MJRA4.5) that - persistence is unsupported for GDFT - we use VLL reservations for generic reservations, ignoring the existing GDFT reservation. - End-End Spec [CP] Fix Savannah issue #14115 - BAR service reservation response does not convert bandwidth to kbps - Note, BAR should work in bps (not in kbps). BAR client should use kbps (with an explanation of what k stands for, i.e. 1000 x bps). [MB] Add to MJRA4.5, the necessity to contact the remote L-NSAP even when a forward only reservation is made. Two important reasons, 1) to inform L-NSAP about incoming traffic to the remote site. 2) to check whether access link capacity is execeed by a reservation [KK] Talk to Pete Clark about possible conferences for paper (e.g. UKERNA Workshop) - Pete is away until mid-March 06. - Try emailing - Pete is in favour of GridNets - Action for CP to estimate effort for writing Discussion ========== GridNets paper -------------- KK spoke to Pete Clark, who favours the GridNets conference. KK noted that the effort for paper should happen this month (= EGEE I) CP to estimate effort and plan paper Workplan -------- Updating Documents: BAR Design has priority over BAR Functional Specification Review: status is currently unknown, timeline is as follows: 01/03/06 review starts; 15/03/06 1st round completed; 31/03/06 review completed; 09/04/06 PEB/PMB approval; 14/04/06 sent to EU Preparations for EGEE I review ------------------------------ KK: It is currently not known what exactly will happen at the review, it might even not be possible to do a BAR demo (e.g. no effort from people available) Technical Reports ----------------- Despite that most of our documents are "technical reports", EGEE formulates now a "new" Technical Report category. We will try to make MJRA4.5 such a report.
