Traffic management becomes critical as your network
infrastructure expands to support different types of traffic and
users. Most traffic management solutions have serious
limitations: too expensive, difficult to use, and overly taxing
on bandwidth. However ProCurve Networking by HP addresses these
requirements, overcomes the limitations of other solutions, and
gives you valuable insight into LAN performance.

TROUBLE IN PARADISE?

As technologies such as VoIP emerge to advance networks, many
believe the tools to manage them are falling behind. Traditional
management software models simply can't keep up with the rate of
real-time change that today's applications sustain. Is there a
solution pending or should network managers rely on their own
innovations? Click here:

Today's focus:

VoIP rollouts generate heat, power concerns

By Phil Hochmuth

Things are about to heat up at Charter Steel. We're not talking
smelters here, but network wiring closets.

Over the next few months, the company plans to roll out hundreds
of IP phones to corporate desktops, with Power over Ethernet (
PoE <http://www.networkworld.com/details/4681.html> ) switches
to run electricity to the devices. The company recently upgraded
its Avaya Definity phone switch to a network of Avaya S8700 IP
PBXs <http://www.networkworld.com/nltechupdate6183> , which are
tied together over IP. This is where things could get hot, says
Peter Schwei, telecom manager for the Saukville, Wis., steel
company.

As the company consolidated its data center and voice
technology, it installed new facilities that also provide the
cooling needs for the new gear. But wiring closet environmental
needs will have to be dealt with as the company switches from
TDM-based handsets to IP phones.Schwei says rolling out IP to
desktops could pose the same problems facing local broadband
providers. "It's the issues in the last mile, so to speak, that
might get us," he says. The need to increase electrical feeds to
wiring closets to support PoE, and the additional cooling systems
required to keep gear from overheating, are now becoming more
obvious as Charter Steel's VoIP deployment moves forward.

"Those are issues we will have to deal with at our distribution
layer," Schwei says. "It's like cleaning out your sock drawer.
You just have to do it."
