From fs@hep.ucl.ac.uk Wed Mar 26 13:44:09 2003 Date: Fri, 28 Feb 2003 09:55:28 +0000 From: Frank Saka To: MB-NG@JISCMAIL.AC.UK Subject: Minutes of meeting 14/02/03 Minutes of the MB-NG operational meeting Date: 14 February 2003 Time: 10:30 am Location:UCL Pearson media lab and via video-conferencing Tel: 020 7679 7029 Present: F. Saka, J. Orellana, I. Bridge, M. Rio Via Video-conf: S. Dallison, G. Fairy, R. Tasker Actions from 4th Collaboration meeting. ======================================= 4.9 S. Bhatti & UKERNA: Arrange to meet with J. Couzens and Experiment 8 people to discuss policies, classification and policing for QoS by 15th Nov 02. Progress: S. Bhatti visited UKERNA on the 21st November. 13/12/02 Ongoing. M. Allenby will help S. Bhatti on setting up a workshop on task 5. 10/01/03 F. Saka will push S. Bhatti on this issue. 31/01/03 A meeting is being arranged with S. Bhatti at his next available slot to discuss this task. 14/02/03 Meeting with S. Bhatti has been arraged for next week. Gantt Chart: ============ Task 3: Traffic generation and measurement (equipment provision) -------- 08/11/02 ACTION: R. Hughes-Jones to arrange meetings to discuss options and what we loose if we do not have GPS. 10/01/03 No progress. This is a low priority. ACTION: UCL to investigate access to UCL based GPS time server (Speak to Lewis Grantham or Piers O'Hanlon). ACTION: S. Dallison to investigate the availability of a time server at Manchester. 31/01/03 Possibility of using NTS servers synchronised by the Rugby clock. The resolution must be checked. 14/02/03 No progress. Task 5: Classification/policies/policing for QoS -------- See Action 4.9 above. Task 9: Managed bandwidth service -------- 01/11/02 On hold until network is in place. Task 10: Plan extension of demonstrations to sites in Europe and US -------- 01/11/02 On hold until network is in place. 31/01/03 A talk on MB-NG and our use of the Spirent equipment should be given at the Internet 2 members meeting. Task 11: The deployment and integration of the Middleware and APIs (GARA) -------- 13/12/02 ACTION: Javier will arrange a meeting with V. Sander (GARA) in February in London. Also with Leon Goomans and S. Bhatti. 31/01/03 Presentation days on GARA and AAA has been arranged for the 20 and 21 February 2003. 14/02/03 Ongoing. Task 12: High throughput programme -------- A document has been produced and has been sent to the MB-NG mailing list. Members are asked to make comments and send them to S. Dallison. 31/01/03 After P. Clarke's recommendation S. Dallison is adding timescales and specific information on the experiments. 14/02/03 Ongoing. 10/01/03 S. Dallison has installed Globus and is intending to investigate the performance of disk-to-disk copy using Grid FTP. The ongoing work on TCP will be integrated at a later date. 14/02/03: We must agree on hostnames and apply for the Globus certificates. 17/01/03 It will be interesting to do GridFTP transfers between UCL and Manchester through the MB-NG network. Paul Mealor at UCL can help with this. 14/02/03 ACTION: S. Dallison to look into the possibility of setting up a central Grid authority. Equipment ========= Status of testbeb ================= 13/12/02 Delivery of the 7600 OC48 line cards is delayed due to manufacturing problems. Delivery of the 7600 Gigabit Ethernet line card has slipped to Q1 2003. 14/02/03 The news from Harvey Lang is that the new OSM OC48 line cards and the Gigabit Ethernet WAN cards are orderable. They are currently on "product hold" until production rumps up (allocation on greatest urgency). M. Mckeown will give us the estimated delivery date later. 10/01/03 Status: TAC case has been raised. The Cisco IOS at CERN will be updated today (from 12.3-11-E1 to 12.3-11-E3). The DataTag link has been reserved and QoS will be tested today. 31/01/03 The outcome of the tests show that the Cisco 7600 router cards are not working properly. We require the enhanced version of the cards. This may be a problem for DataTag. 14/02/03 Huw Jones has forwarded the setup details to Cisco USA. He will let us know when results are available. Meanwhile we will test the Gigabit Ethernet WAN at CERN to see if it supports QoS. 13/12/02 I. Bridge: There is the possibility of a project TAC support and access to a CISCO techie (Huw Jones). Status: The issue is currently left with Mike Mckeown. It was agreed that we will push him on this at a later date. 17/01/03 ACTION: P. Clarke to contact M. Mckeown about TAC access. 14/02/03 Ongoing. Task 7: e2e Network equipment configuration -------- 22/11/02 ACTION: R. Tasker should make a suggestion on the addressing scheme to be adopted by the project. Status: R. Tasker has produced a document for comments. 17/01/03 The current proposal is to use site IP addresses and static routes 14/02/03 The addressing scheme has been agreed. Experiments ============ Task 8: QoS Experimental measurements -------- 13/12/02 ACTION: A schedule of tests should be drawn up. Ongoing. 14/02/03 This action is postponed until the March report is finished. It also depends on the available equipment. Spirent would like us to test their QoS conformance test suite. We should look at it, but we should not spend too much time on it. Spirent would also like: Reports on our tests. A mention in publications and at network workshops. Any TCL scripts developed for tests. For MB-NG's use of Spirent equipment to be presented to Internet 2 Tests are being done on the GSR. Test on the 7600 will be started at the next week. 14/02/03 A report on the OSR and GSR tests are being written. ------------------------------------------------------------------ Tests for the March report. Booking Cisco's Bendfont lakes for standalone tests. This will be interesting after the completion of the project report. We need to discuss: - Equipment we require and confirmation of availability - Plan of test we need to carry out (We will only have two days). - Who will be going. Proposed test for MB-NG QoS 1. Latency(end-to-end): Back-to-back and through the network. For each packet size. Without congestion. 2. Three streams. Maximum throughput through the network. No policy. Packet size 1472. 3. 2LBE and 1BE flow with policy 98%BE 1%LBE 4. Policing and re-classification. 5. Rate limiting. Limiting the 2.5 Gig POS interface to 1.0 Gig. If this works then we can assess whether we can congest the GSR's output port. This may allow us to QoS. We must also check at what level MDRR works. Based on the results of tests 4 and 5, we will decide whether to use the 7200 in the multi-domain tests or not. Issues: Throughput measurements for Manchester to London is only 400 Mbit/s per host compared with 957 Mbit/s in the reverse direction. ACTION: Check the tests again without the Manchester Firewall and Web server.
