Today's focus: Survey says VoIP fears hinder adoption

By Denise Dubie

A recent survey shows that network managers worry how voice
could affect their data applications, and that worry could
hinder their plans to roll out VoIP.

Network General, maker of Sniffer Voice
<http://www.networkworld.com/news/2004/0716sniffrelau.html?rl>
and other network management tools, conducted the survey of 100
network managers with research firm Enterprise Management
Associates and found the perceived or potential performance
impact of voice applications was a primary inhibitor to
full-scale enterprise deployments of VoIP.

Nearly 60% of respondents are already using VoIP as their
primary voice communication system, and about 50% have been
using VoIP for more than a year. But according to the survey
results, nearly half of IT managers surveyed discovered that
"both VoIP and data applications were impacting each other,
resulting in degradation of overall network performance."

Jim Vale, Network General's product manager for Sniffer Voice,
says the fear of performance degradation has many survey
respondents keeping their voice deployments smaller than if data
network performance had not been affected.

"We found that the majority of North American companies polled
were doing something with voice, and of that, many are doing it
in limited deployments," he says. He says the concern over
performance could be why more than two-thirds of IT managers
used performance network capacity planning tools, upgraded
bandwidth links, and installed network and VoIP monitoring tools
prior to their VoIP rollouts.

In fact, 51% of respondents said they found VoIP management
tools <http://www.networkworld.com/nlnetop3278> to be critical,
while 39% found them very important. Only 10% said VoIP
management products were somewhat important. Also, the survey
found that 77% of respondents were using their current network
and application management tools to address the new voice
applications.

Another noteworthy item, according to Network General, is that
6% of managers believe that tools to manage voice and data must
overlap, in the case that one person or group is responsible for
both network and voice application performance.

"The overlap indicates to us that the telephony team will need
to know how to manage data and vice versa," Vale says.
