Saka, J. Orellana, P. Clarke, A. Di Donato, I. Bridge, M. Rio Via Video-conf: M. Allenby, C. Seelig, R. Tasker, S. Dallison, A. Ryan 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. 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. 4.11 M. Rio. Document finding on Cisco bugs/experiences. CEF issue TAC with Cisco has been closed due to slow slow progress and since we will not be using the 7200 in the development network. 10/01/03 Done. The document will be placed on the private area of the MB-NG website. 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. 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. 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. 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 Gooman and S. Bhatti. 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. 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. 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 sucess. ACTION: A TAC case will be raised via CERN. 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. 13/12/02 I. Bridge: There is the possiblity 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. Task 6: Lab based network equipment configuration -------- 13/12/02 At RAL and Manchester, the 7200s have been put into racks. At UCL, rack space needs to be sorted out. ACTION: Speak to B. Cranfield on this issue. Done. UCL rack is expected to arrive today. The equipment should be in place sometime next week. Task 7: e2e Network equipment configuration -------- 08/11/02 Ongoing. M. Allenby will talk to Robin Tasker and D. Rogerson about distribution of the IP addresses to the MB-NG sites. 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. 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. Tests are being done on the GSR. Test on the 7600 will be started at the next week.
