EURESCOM P813: Technical Development and Support
for European ATM Service Introduction
Peter Feil, Deutsche Telekom Berkom GmbH
Harrie van de Vlag, KPN Research
John Boyles, Project Leader P813
AIMS’99 Workshop
Heidelberg, 11-12 May 1999
Pan-European ATM Services
What is needed?

Interoperability beyond PNOs’ borders

More that just global alliances

Managed ATM interconnectivity across PNOs and
alliances

One-stop shopping preferred


146 MM Project
 start 23 June 98, completion December 99
Shareholders:
 AF, AU, BT, DT, FT, HT, IT, NL and NT
Other informal company participation (NEC, Nokia,
etc.)
Project Redefinition in December 98

Task 2: U&C Plane and Management
Plane issues of ATM Services

PIR 2.1 Enhanced Leased-line services

PIR 2.2 Market-driven VPN scenarios
for voice and data

PIR 2.3 ATM as a backbone for IP,
thereby examining alternatives, e.g.:


end-to-end connections
hop-by-hop connections

ATC 2
Task 2: U&C Plane and Management
Plane issues of ATM Services

Which ATC(s) can transport the higher layer service

How will the higher layer service be implemented on the chosen
ATC(s) ?

Which relevant QoS parameters have to be translated to ATM
QoS Parameters (in other words, have an impact on NNI.easi)?

Will the management of the higher later service have effect on
X.P813? If yes, how?

Are the current specifications (under development) sufficient, or
are additional guidelines for User&Control Plane or Management
Plane necessary?
AIMS’99 Workshop

ATM as an IP-backbone (PIR 2.3)

Routed IP backbone

IP overlay network (over ATM)

MPLS for IP/ATM integration

IP over optical Networks
AIMS’99 Workshop
Heidelberg, 11-12 May 1999
IP over ATM benefits

Flexible configuration of capacity and topology

Enhanced traffic engineering features of ATM:
traffic classes and QoS support
traffic policing and shaping



Redundancy/backup

better monitoring and statistics

network capacity planning
AIMS’99 Workshop
Heidelberg, 11-12 May 1999
Next step within P813 P.I.R. 2.3

Identify all IP-over ATM overlay network options

Select relevant options and necessary specs

check whether the existing User, Control and
Management plane specs. can optimally support
these options

advise ETSI/EASI on enhancements on the user &
control plane if necessary

advise P813 Task 3 on enhancements on the ATM
management layer if necessary
