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

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)

22
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

23
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

24
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)
