  1. IN and B-ISDN Signalling Integration on ATM Platforms Participating European Countries:

  2. Project Overview Bert F. KOCH Germany Bert.Koch@oen.siemens.de http://www.fokus.gmd.de/nthp/insignia/

  3. Overall project objectives • Demonstration of trans-Europeanswitched ATM networking starting spring '97; • Interconnection of islands in Germany, Italy, and Spain

  4. Equipment Manufacturer Network Operator Research Consortium Siemens GMD-FOKUS NTUA Telefonica de Esp. CSELT Italtel GPT Prime Contractor Spain Greece United Kingdom Italy Italy Germany Germany Univ. of Twente F U B Siemens Schweiz CORITEL Switzerland Italy The Netherlands Italy Telecom Italia Siemens ATEA Belgium Italy Deutsche Telekom Germany

  5. INSIGNIA Intelligent Network Architecture • New object-oriented session model in B-SSP for the co-ordination of complex connection configurations • New service logic (and creation environment) for multimedia services • New concept for Broadband IP (Intelligent Peripheral) • Broadband end systems B-SCP IN interface Service Logic B-IP IN interface UNI Signalling B-SSP1 B-SSP2 Session Model End System UNI Signalling NNI Signalling

  6. Interfaces and Protocols Colour Code: B-INAP B-SCP New TCAP IN interface Subset SCCP MTP-3B Unchanged SAAL(NNI) B-IP ATM IN interface UNI B-ISUP B-SSP1 B-SSP2 DSS2 MTP-3B SAAL(UNI) SAAL(NNI) ATM ATM End System UNI NNI

  7. Network Service Broadband Virtual Private Network B-VPN Multimedia application services Interactive Multimedia Retrieval IMR Computer Supported Cooperative Work CSCW Selected services for the first trial

  8. Islands for the First Trial NH JAMES NH NH

  9. Physical and Virtual Networks VPN is an end systems independent network service

  10. B-SCP B-SSP Calling User Called User Influence of service logic Call set-up (by user) User-initiated connection Broadband Virtual Private Network Service

  11. B-VPN: On-net-to-on-net call, international MUC3 MAD1 MUC2 MAD2 MUC1 VPN Call Display European ATM network B-SSP B-SSP Munich Madrid B-SCP B-SCP

  12. B-SCP B-IP (Broker) B-SSP Set TopBox (STB) Video Server TV Influence of service logic Call set-up (by user) User-initiated connection SCP-initiated connection Broadband Video on Demand Service

  19. Island and connections for the First trial

  20. Main Difference between First and Second Trial B-SCP B-SSP Second trial: Some IN service requests handled by remote SCP (SSP-SCP signalling through wide-area network) User First trial: All IN service requests handled by local SCP B-SSP B-SCP

  21. Centralized SCP per service (remote SCP) User-Service interaction (UTSI / STUI) Relationship between B-IN and TINA New Service: Broadband Virtual Intranet (VPN applied to private TCP/IP networks) Second Trial (Summer 1998)

  22. Network Service Broadband Virtual Private Network B-VPN (supporting applications like Broadband Video-Telephony and Virtual Intranet) Multimedia application services Interactive Multimedia Retrieval IMR Broadband Video Conference B-VC Selected Services for the Second Trial

  23. B-VPN Remote VPN Access and Follow Me (these features make use of the User Service Interaction) IMR Different applications (VOD, NOD, MOD) within a single service instance Reconnection to the broker when the selected content ends B-VC New procedures: Invite, Disconnect and Invitation Checking Additional Service Features for the Second Trial

  24. Realizes a logical subnet of the public Broadband ISDN to support corporate Intranets (TCP/IP) Based on generic INSIGNIA VPN service Endsystems support Classical IP over ATM Access security provided by the IN (User Registration and Subscription in SCP) Incorporation of traditional LAN Intranets via Proxy Server Technology Broadband Virtual Intranet

  25. WEB Server C B-SCP WEB Server B WEB Client 1 B-SSP Other parts of Intranet (e.g.LAN) ATM Network WEB Server A (Proxy) WEB Client 2 ARP-Server Influence of service logic Call set-up (by user) IP over ATM Address Resolution Broadband Virtual Intranet

  26. B-VI: On-net-to-on-net call, international WEB Server 3 WEB Server 2 (Proxy) WEB Client 1 WEB Client 2 Intranet-LAN B-VI / VPN WEB Server 1 WEB Client 3 European ATM network ARP Server B-SSP B-SSP B-SCP (remote) Madrid Munich

  27. TINArized SCF, SDF, SMF (Service Objects) Adaptation unit AU Traditional Signalling and (IN) Switching Object-orientedSSF CCF Possible Relationship between INSIGNIA and TINA

  28. Implementation of B-IN network elements Implementation of advanced multimedia services based on native ATM B-IN and B-ISDN field trials via European ATM network Performance models and measurement for B-IN Contributions to ITU-T standardization (ITU-T: IN CS3) Conclusions
