In its former premises, NNIT could not efficiently manage the use of wireless
devices. An attempt was made unsuccessfully to implement wireless security
enforcement as an add-on to the wired network. In contrast, the NNIT integrated
wireless strategy in the new building is already delivering important benefits. For
example, unauthorized devices are denied access to the network, and thanks to the

“We now have a network that recognizes individual devices, and that’s allowed us
to authorize some specific platforms to access the network. And we have seen no
problems with integrating them,” says Barnow. “It’s a great relief that we can plan
ahead with the reality of a common network and a common experience for all our
users and customers. It’s a great solution, in terms of management and functionality.”

Identifying and locating rogue wireless devices and Wi-Fi interferers was also an
issue in the old building, particularly when employees introduced potentially disruptive
appliances that the IT department did not know about, or moved devices to a new
spot. Thanks to Cisco CleanAir technology, the network identifies potential interference
and changes the radio frequency without any service deterioration or interruption.

NNIT is still at an early stage in exploiting the deeper business benefits of its Cisco
Borderless Network architecture, but in the near future sees it as providing an exciting
platform for demonstrating best practice to existing and potential customers.

“Already, the response from our customers has been very positive, and they are
asking for quotes on projects that involve many aspects of our Borderless Network
deployment,” says Barnow. “It’s helping to differentiate our services and show how
elements of the network’s functionality can meet different needs. Our customers can
see it’s a good product and something to build on for the future.”

Perhaps the most visible benefit, however, has been the improvement in the delivery
of video services to the desktop and the conference suites. Previously, the IT team
was unable to prioritize video streams without knowing the IP addresses of the video
end-points and manually configuring ports on the LAN switches. Fluctuations in
bandwidth availability often led to problems with call set-up and videos freezing in
mid-play.

With Medianet, this problem has been eradicated, a requirement that was essential
for projects requiring collaboration between NNIT international offices. Employees can
now communicate with each other around the world with the ease of room-to-room
conversation. And the reporting function provided by the ISE is another highly-visible
demonstration of how effectively the Cisco Borderless Network Architecture can be
used to satisfy regulatory compliance, while also enabling the smooth delivery of
business-critical multimedia applications
