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

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

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

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

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

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

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

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

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
