2. Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 2 Background ATM technology is mature Products are available National and alliance ATM networks exist Standards EURESCOM results provide a good basis for further deployment The time has come for deployment of managed ATM networks on a European scale

4. Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 4 ATM MoU had problems Initial European Plan ATM MoU (ETNO) Project EASI Technical Committee NA8 etc. Projects P813 and results from P616, P707, P708, P710 and others ATM issues Network management Standards for interoperable European ATM service

5. Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 5 How to fulfil customer needs? An alternative for the ATM MoU steering group is needed The idea of a “virtual” MoU to steer P813 and EASI to their goals was born Guidance is needed for P813 and for ETSI EASI An ATM introduction steering group will fulfil this role

12. Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 12 T2: Control and User Plane issues of ATM Services Leased-line services over ATM and how this affects resource reservation Market-driven VPN scenarios for voice and data ATM as an Internet Protocol backbone, thereby examining alternatives, e.g.: end-to-end connections hop-by-hop connections

13. Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 13 T5: Unresolved Traffic Issues Dealing with Call-level Congestion Investigating Available Bit Rate (ABR) in connection with TCP/IP, especially TCP / ABR interaction Wireless ATM and integration of mobility
