Di Donato, I. Bridge, M. Rio Via Video-conf: S. Dallison, G. Fairy Actions from 4th Collaboration meeting. ======================================= 4.6 UKERNA & P. Clarke: Make contact on making sure RAL link is lit on 1st March. 13/12/02 Ongoing. UKERNA have written to P. Clarke who has to generate a letter. 17/01/03 Done. 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. 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. Task 5: Classification/policies/policing for QoS -------- See Action 4.9 above. 13/12/02 ACTION: M. Allenby will distribute slides J. Couzens' presentation on DSCP on regional networks. 17/01/03 Done. 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. 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. 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. 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. 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. 13/12/02 The 7600s have been delivered. A ping has been performed through the development network between UCL and Manchester. 13/12/02 The UCL group have tried to get QoS working on the 7600s at CERN and on the MB-NG equipment without success. 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. 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. Task 6: Lab based network equipment configuration -------- 17/01/03 At UCL and Manchester, the equipment have been put in their racks. 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 Experiments ============ Task 8: QoS Experimental measurements -------- 13/12/02 ACTION: A schedule of tests should be drawn up. Ongoing. 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. AOB ===== Next meeting: 14th February 2003.
