Conferencing – Market Status
• How big?
•
$14 billion by 2005 = 38% compound growth from 2000 to 2005
(IDC: July 2001)
• Home Market
•
•
Low bandwidth (traditionally – but changing)
Video phone + chat + adult
• Vertical
•
•
limited deployment
Helpdesks, call centres
• Corporate
•
•
•
•
Security / firewalls
Measurable benefits – cost/fear of travel
Other benefits - improved work practices, productivity, morale
Strong bias to data

What’s Next?
Conferencing Limits
• Access
•
•
local and wide area
Equipment/security
• Bandwidth
•
•
•
Audio requires 5-64 kbits/sec, video requires 150 - 500 kbits/sec
Latency
Infrastructure
What’s Next?
• Web
•
Fast growing
• use anywhere
• no install (saves a lot of money)
•
Lack of standards
• opportunity for bridging between web and traditional clients like NetMeeting
• Conference Servers
•
•
•
•
In-house or via ISP (hosted)
Security, management
Bridging communications – IP and PSTN
Services – web “proxy”, recording
• Development of infrastructure
•
•
More bandwidth
QoS in VPNs
• predictable bandwidth
• predictable latency
• charging
What’s Next?
Email was the major corporate growth
“technology” of the 90’s ...
Conferencing is a major corporate growth
“technology” in the new millennium
