Broadband Services
• People of Same Household Online Simultaneously
Browsing Web, Downloading Information and Updates
(Symmetrical & Asymmetrical- Interactive Services)
• High Speed Streaming Video on Televisions & Computers
Internet Access, Cable Television Service, and Wire-line
Voice preferably from the same Company
• Video Chat Rooms for Video Calls, Music Videos, Infomercials, Distance
Education, News Clips in Residential Areas
• Virtual Presence for Interactive Business
• Virtual Ubiquitous Global Offices for Business
• Virtual Private Networking, Database Access, e-Commerce
Instantaneous Availability of Information from Anywhere to Everywhere
Broadband Triple Play
• Triple play?
– TV, Internet, Phone ( Video as part of TV & Internet)
ISP/Telco Model Computer/Telephone Centric
Cable Model TV Centric
Cost of accessing services may only be related to type of
services and not to the city or distance from the local
point of service
• MSO (multi-service operators) investing not only in
networks, equipment and external plant but also in
application servers, delivery mechanisms, content,
application development, additional build-ups ?
Interesting Broadband Scenarios
• Hong Kong Population 6.8 million, Household 2.2 million
Broadband connections 1.2 million (1.1 million house
hold) 14 DSL lines/100 population; 28 DSL lines per 100
telephone lines
• In Japan BB driven by content for different age groups
• In Korea BB driven significantly by local content
• Access owner- service provider - content provider
• Revenue as ratio of investment in that order
• In India BB may be driven by Entertainment: Interactive
TV , time-shift TV, video on demand, music on demand,
multiplayer gaming, education at home, sky shop rather
than internet shopping. Of course net browsing and data
transfer.
• How much symmetrical !
The Intelligent Services Layer of the
Networks
Service Plane = Service and Application Layers
Service Control Logic out of switching/routing systems
Service nodes used as shared resources
Transport Layer of Telecommunication Network
Transparency of Layers to make Design and
Deployment of New Services Almost Instantaneous
