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

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

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?

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

PROPOSAL
Set of organisations with bandwidth demand.
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.

Does it work?
Management issues of the TEN-155 MBS
TNC 2000, Lisbon 23 May 2000
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
Management issues of the TEN-155 MBS
TNC 2000, Lisbon 23 May 2000
… 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

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

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.
