Today's focus: IP apps challenge today's networks and staff

By Denise Dubie

New applications such as voice over IP and video are going to
change the way network managers deal with application
performance. In fact, the move to more IP-based applications may
leave some network managers feeling a bit more like application
managers.

Traditionally, network managers ensure LAN devices and WAN
performance remain up to snuff, either with monitoring tools or
creative network architectural engineering, but industry
watchers say the trend to adopt more IP-based applications will
have network managers caring more about application performance
than feeds and speeds.

In fact, the switch from network engineers exclusively caring
about ports and bandwidth to also monitoring application service
levels will initially challenge most IT shops. Optimizing
performance of IP-based applications will take new technologies
as well as new perspectives on the part of network engineers.

"The real problem is that people roles will be changing, and no
one is sure quite yet into what they will be changing," says
Jasmine Noel, a principal analyst at research firm Ptak, Noel &
Associates. "There is going to be confusion over where the
network and the network managers' responsibilities end and when
the application team takes over. In this converged world, how
the application behaves tightly depends on how it's being routed
through the infrastructure and really who has responsibility for
that?"

VoIP will test today's networks and IT shops to better track
performance through a few different parameters, such as latency,
jitter and packet loss.

VoIP applications are forcing one vice president of IT to
reassess how he manages all traffic on his network. At White
Electronic Designs, a provider of integrated silicon and
advanced packaging services in Phoenix, Ariz., voice is pushing
the current network to its limits, says James Kritcher. To get a
handle on it in the future, he says the staff will have to find
new tools and start thinking differently about how it manages
the LAN and WAN if the company decides to support a fully
converged IP network.

"We'll need analyzers with expert diagnostic capabilities for
both data and VoIP traffic," Kritcher says. "You can't run VoIP
systems the way you do your LAN and WAN because of the dual
nature of voice technology and data network technology."

THE ROI OF VOIP

When it comes to VoIP, most network managers are satisfied that
the technology works. But there are questions: What will the new
technology cost to roll out and support, and what benefits can
companies expect to reap? Check out NW's step-by-step guide on
how to determine the true cost and benefits of VoIP. Click here:
