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

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)

Second Trial (Summer 1998)
selected services for the second trial
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
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

Additional Service Features for the Second Trial
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

Broadband Virtual Intranet
