Why do we need an NGN?
ITU-T
NGN
Technical
Workshop
• Existing Broadband deployments
• Fast Access to the Internet
• No Services
• Commercial Model
•
• Customer to ISP
• Customer to Content Provider
Falling PSTN/ISDN Volumes

NGN and the Internet
ITU-T
NGN
Technical
Workshop
• The Internet is characterised by:
• Variable reliability, Rapid Service
Deployment, Rich content, Multimedia,
No sustainable business model, lack
of security
• The PSTN is characterised by:
• Universal Service, High Reliability and
Availability, Slow service deployment,
Good business model, Trustworthy.
