2. Information and Communication
All human sensory organs communicate with the brain and provide information or inputs
Speech and body language are most common ways of communicating to the external world
Older ways of communication technologies had limitations to deliver all that was needed for perception
New communication technologies allows delivery of many of sensory information to be delivered digitally

3. What is convergence ?
Ability to deliver voice, data,sound & images though universal network.
In common man’s language
Integration of functionalities of PC, Phone and TV
Analogy
Ability to pump “solids, liquids and gases” through the same pipe efficiently

4. Converged networks
Based on internet as pervasive communication network
Hence typically IP networks
Physical layers could be copper, fibre or even air (wireless) or a combination all different modes

5. Protocols in the converged world
ITU-T H.323
Originally designed for ISDN based video conferencing
Integrated application and delivery
SIP – Session initiation protocol
Designed for delivery
Clear segregation of delivery and applications

6. Some underlying protocols
DSL
B-ISDN
ATM / Frame relay
SDH/Sonet

7. Some important challenges
The last mile problem
Broad band wireless
DSL on copper
Cable (as used in cable TVs)
Bandwidth Utilization
Applications to be developed for available bandwidth (Low or high)
Bandwidth availability is location and market sensitive

8. Converged services VoIP communication - Video over IP – Videophones
Presence based applications
UMS – Unified messaging systems
Delivery of messages based on available device…..

9. Deploying converged networks
Issues
Economics
Legal framework
Bandwidth
Examples
VoIP service for Corporates
VoIP service for individuals

10. Convergence in wider context
All “Real world” applications are interdisciplinary
There is a strong need to understand variety of domains and technologies
Lateral thinking for understanding multidisciplinary challenges
All technology becomes software+data
Software architecture IS communication architecture
