Changes and DiscontinuitiesWhere Should Intelligence Reside?SG 13 Work on “Future Networks”Some Thoughts on the Future

Fundamental Changes in Telecoms

Started with TelegraphData (Morse code)

Every Transport Technology

Everything Over IP andIP Over Everything


Telecommunications Industry: Constant Innovation

Analog to Digital

Wireline to Wireless

Copper to Fiber

Wireless to WiMAX/4G/LTE

VoIP and Converged Communications

VoIP and Converged Communications

Change comes from disruption. And disruption is constant!


Discontinuities

Transition from Fixed to MobileGrowth of fixed services slowing, turning negativeMobile phone growth continues but levelling off due to market saturation


Data Network

Discontinuities

Transition from Analog to DataOn circuit-switched (analog or TDM) voice networks, data is handled by making it look like voice (modems)

On packet switched data networks, voice is handled by making it look like data (VoIP)

Phone Network


Discontinuities and Convergence

Once we just had a telephone on our desks.Then we added a computer mainframe terminal,but replaced that with a personal computer …… which became portable (laptop), …… we added wireless networking including voice, but we shrunk them a little too much …

… so we enlarged them to just about the right size.


Outline



Intelligence was centralized, but is it in the right place?

We began with human operators “inside the network” handling switching and services for “hard-wired” subscribers, …... “progressed” to analog mechanical circuit switching (SxS), ...

... refined it with stored program control (#5 XBar, SP1), ...


We continued with the assumption that terminals were “dumb” …

We converted from analog to digital transmission and switching.We centralized network intelligence into with replicated islands of intelligence enabled by common channel signalling.


… but ISDN and Mobilitychanged everything!

Suddenly terminals had to be able to do a great deal more:

A functional ISDN terminal is a de facto 2 line exchange!

Cellular networks added a new dimension to what terminals had to do:

Mobility!


Evolution!

We’ve gone from one extreme to the other:

Start: all intelligence in the network and none at the edges “dumb” terminalsAdvances in technology enabled intelligence to migrate to terminals connected to a “dumb” network

Neither end of the pendulum swing is ideal …

“Bell-heads”

“Net-heads”

The world is rapidly becoming Hyperconnected!


Hyperconnectivity

Anything that can be usefully connected will be connected


Communications-Enabled Applications

• Reinvention of services and applications to support new levels of network-aware intelligence and an intuitive interaction experience• Achieve through advanced technology

frameworks such as IMS and Services Oriented Architecture (SOA)


True Broadband

• The communications experience is so seamless that users no longer have to consider which technology is being used to make a connection.

• Users simply communicate, anywhere, anytime from whichever device is most convenient. Most importantly, the broadband experience becomes so economical that the range of uses exceeds any experience of the past.
