EC funded project, research, etc What we do Evaluation of TEN-155 MBS for the project network needs. Group Network Manager to read service definition and procedures. Coordinator Project Information Equipment to connect Countries involved Submission of project requirements to DANTE, by mail or using ten-155 MBS web site. AGREEMENT Project ID Mail to the ASMs with project id Agreement on network resources usage. Arrangements for national connections between projects equipment and TEN-155 POP • • Document with the projects needs and how to satisfy them. Request is sent to the TEN-155 ATM NOC. Resolution of resource allocation conflicts. Management issues of the TEN-155 MBS • 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. TNC 2000, Lisbon 23 May 2000 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.

Management issues of the TEN-155 MBS TNC 2000, Lisbon 23 May 2000 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 userfriendly • Look at the next generation European projects participating in the V Framework. • Evaluating alternative techniques to support the service (MPLS, diff-serv) Management issues of the TEN-155 MBS TNC 2000, Lisbon 23 May 2000 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.
