6. Corporate Video is poised for
growth…
Two key business drivers for
videoconferencing adoption: the
need to improve collaboration for an
increasingly virtual workforce, and
the desire to use video to reduce, or
offset, reductions in travel spending

But it has not taken off yet…

7. Where we are today
MLPS
Carrier A
•Is the LAN QoS enabled ? Has carrier
•Does the LAN have the capacity ?
•Can video pass thru firewall ? implemented proper
•Are the specialized networking people QoS for Video?
to design real time traffic available?
GW How do you video with
community of interest –
different carriers, different
QoS, security issues?
MCU
MLPS
Carrier B
•Right QoS for Video on WAN??
•Enough affordable bandwidth for MCU?
•ISDN available for legacy calls?
• Video infrastructure designers available?
•Networking people available?

8. Challenges
 Per Frost and Sullivan, major challenge that the high-end visual
collaboration services providers are facing is the low awareness of the
benefits and the ease-of-use of visual collaboration tools among business
leaders. A common misconception, quite prevalent until recently, was that
those tools and services were difficult to use, required extensive
expertise, and were reserved mostly for the upper executives.
 However there are real challenges…
• Network: Bandwidth may not be sufficient or network may not be
architected correctly
• Communities of Interest: Inter-provider video is still difficult and
security is a concern
• Infrastructure Equipment: Infrastructure equipment needs to be set
up correctly, securely stored and widely accessible
• Troubleshooting: Management of devises and calls is difficult
• Video Call Set up: call set up is easier but may still be a challenge

9. Challenge: Network
 Video networks can be ISDN, private networks like
Ethernet or MPLS and/or use the public Internet
• May be corporate networks or be dedicated
 If you have problems with Video, the network may be the
problem:
• Know what you have – audit your network capacity
especially to smaller locations – more bandwidth may
be the answer
• Manage and shape traffic
• Use wan optimization devises which can reduce non-
real time traffic loads by 50%
• Optimize your network architecture

10. Challenges: Communities of Interest

other companies?

13. Challenge: Infrastructure
Equipment
 Video screens are located on the premises with the users
 However, infrastructure equipment (bridges, gateways,
gatekeepers) can be anywhere but need to be secure and
accessible
 Look at locating infrastructure equipment in a carrier
neutral colocation center:
• Cost effective, flexible space and power
• Back up and redundant cooling and power
• Secure controlled access
• Low latency access to the end users
• Access to different carriers
• 24X7 technical support

14. Challenge: Managing video application
end to end

15. Summary
 Video Conferencing is poised for growth.
 Manage the challenges
• Network: Architect your network to support video
• Communities of Interest: Connect to a business to business video
exchange to support communities
• Infrastructure Equipment: Secure your equipment in a carrier neutral
colocation facility
• Troubleshooting: Manage the calls end to end
• Call Set up: support either internally or with a managed service provider
 Telx can help
• Provide network choice
• Form business to business communities in the Telx Video
Exchange
• Be a secure place to store equipment
• Offer software that enhances troubleshooting and management
