  1. Management Issues of the TEN-155Managed Bandwidth Service Roberto Sabatino DANTE TNC 2000, Lisbon 23 May 2000

  2. Services in TEN-155 • Best Effort IP (classical): • IP connectivity for National Research Networks • Interconnections (ABILENE, NACSIS, ESNet, CAnet) • Native Multicast • ATM based • VPNs • end to end BW guarantees - interdomain • for pan-European Research projects

  3. MBS overview • ATM PVC: VCC VPC • CBR, VBR • permanent, scheduled, periodic • up to 20% of NRN access • direct connections to TEN-155 possible

  4. What do we mean by Quality: • Everything that can be set with ATM: • Bandwidth • Flow control • delay • jitter • delivery • availability … that is nothing new, where is the challenge?

  5. Coordination and Management !

  6. Service Overview • Management Boundaries

  7. A good Example:

  8. Three ways of doing things Spain Italy Austria Hungary CERN Czech Republic Poland Luxembourg Portugal Israel Slovenia Ireland Nordic Countries (SE, NO, IS, DK, FI) France Greece Switzerland Belgium Germany Netherlands UK Service in Place, operational procedures in place covering connected institutions Defining Service, draft procedures No Service defined, DANTE as a “proxy agent”, agreed procedures

  9. The Group Network Manager • From the project paticipants or users • Collects information from user nodes, liasing with national ASM (ATM Service Managers) • technical • administrative • Can “make things happen”: • technical knowledge • right contacts within National organisations

  10. What is the service scenario? Users

  11. What we do • Receive the contact from the project • Get information about the project: • Sites • Bandwidth • Schedule • If we consider it feasible, create a topology map, disseminate information and wait for the NRN green flag.

  12. What we do next • Once the general requirements are accepted, we ask for implementation details: • Information about the sites. • Technical contact. • Administrative contact. • Equipment. • Time slots. • Bandwidth profiles. We create the plan with that, and implement it.

  13. And “detail” means: • Project Site: • Tech contact: (the one in control of ATM config) • Name • Address • Phone • Fax • Mail • NOC-mail (for outages and troubleshooting) • Admin Contact: (the one "owning" the port) • Name • Address • Phone • Fax • Mail • ATM port: • Equipment code (if existing) • Address (ATM/IP?) • Location: • Address • Room • Rack • Connectors positions • Vendor information: • Vendor • Model • Hardware/software revision • Features • Remarks: • PVCs and Time slots: • Origin (Port@site): • End (port@site): • from (UTC time): • to (UTC time): • Periodic? (period specification) • Usage (purpose, video, IP, best effort, etc) • VPi or Vci: {VP/VC} • vpi (local/remote) • vci (local/remote) • ATM traffic capability: {dbr/sbr2/sbr3} • pcr (forward/backward) cells/seg • src (forward/backward) cells/seg • mbs (forward/backward) cells/sec • BW in mbits/sec (generic requirement) (forward/backward) • Comments on config (origin/end)

  14. Does it work?

  15. We have tested in an alpha phase... • one project (MECCANO/ERCIM) • 3 countries (DE, FR, UK) • January to end of March ‘99 • Objectives: • “to do something simple successfully” • to establish the procedures for using the MBS • to identify issues re: interworking with NRNs • to identify issues re: internal NRN workings

  16. … and beta: • Objectives: • expansion to more projects in more countries • validation of procedures • resolution of issues identified in the alpha-test • 8 projects/groups including: • 4 EC co-funded research activities • 2 research activities between universities and research institutions • 2 research activities within QTP/TF-TANT • 11 countries (AT, CH, DE, ES, FR, GR, HU, IT, NL, UK, + CERN) • April to end of June 1999

  17. Yes, it works.

  18. EDISON, Application #1 : Spacecraft Validation with ‘Hardware-In-the-Loop’ Close-loop & real-time flight simulation of the spacecraft: Delay and Jitter are critical: delay under 50 ms, with 5ms tolerance Real spacecraft, integrated in France Real motion system for space proximity operations, in Germany

  19. DIFF-SERV experiment(QTP / TF-TANT)

  20. Pending issues • Set-up time around one week. • Existing bandwidth and management limitations. • It is not “plug and play”.

  21. Next Steps • Keep working on improving the actual service. • Create a good “ATM Service Map” describing the actual status and procedures in all the countries. Make it user-friendly • Look at the next generation European projects participating in the V Framework. • Evaluating alternative techniques to support the service (MPLS, diff-serv)

  22. Conclusion • TEN-155’s Managed Bandwidth Service provides end-to-end guaranteed service today. • It works in the multi-management domain. • It will be continued in the next generation network, GEANT • Can set the basis for developing similar services nationally.
