Second Trial (Summer 1998)

• 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)


Selected Services for the Second Trial

Network Service

• Broadband Virtual Private Network B-VPN B-VPN (supporting applications like Broadband Video-Telephony and Virtual Intranet)

Multimedia application services

• Interactive Multimedia Retrieval IMR IMR

• Broadband Video Conference B-VCB-VC


Additional Service Features for the Second Trial

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


Broadband Virtual Intranet

• 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

Conclusions

• 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)
