Today's focus: Microsoft to overhaul its Wi-Fi net
By Joanie Wexler
Microsoft, which has long operated one of the largest enterprise
Wi-Fi installations in the world, has committed to an entirely
new wireless LAN infrastructure, which it will begin deploying
this month.
The software behemoth will move some 25,000 simultaneous users
and 100,000 devices, which span more than 60 countries, 277
buildings and 17 million square feet, off its aging Cisco
Aironet infrastructure and onto an Aruba Networks Wi-Fi net. The
revamped network will comprise 5,000 to 6,000 thin APs and about
100 Aruba switch/controllers, according to Aruba officials.
The driver behind the multimillion-dollar deal?
"Microsoft has said it needed to improve performance per user,
address security in a more integrated way, and improve
scalability," says Don LeBeau, Aruba president and CEO. He also
notes that Microsoft will run Longhorn, the newest and
security-centric version of Microsoft Windows, on its own
internal Wi-Fi network before bringing it to market.
Microsoft has been shopping for a replacement infrastructure for
approximately the past year. At about that time, it deployed
Aruba's air monitors and RF Director software as a global sensor
overlay to its Cisco network to detect rogue access points for
security purposes.
"Our sensors became part of Microsoft's drive for looking at
next-generation technology," asserts LeBeau. "They found that
they could operate round-the-world security but manage it from
just a few centralized switches [at Microsoft headquarters]."
Microsoft began building its original WLAN using equipment from
Aironet Wireless Communications (which was subsequently acquired
by Cisco) in 1999, long before sophisticated RF tools and
centralized provisioning, management and security platforms hit
the market. It wound up building its own management
architecture, a process that took about four months but allowed
the company to operate its worldwide WLAN with a very small
staff (see newsletter, "Microsoft supports 4,500-AP WLAN with
five people," <http://www.networkworld.com/nlwir2537> ).
The next-generation WLAN architecture should allow Microsoft to
reduce, by two orders of magnitude, the number of managed Wi-Fi
devices, because only the switch/controller devices require
management, not thousands of APs.
Microsoft selected the Aruba platform after a technical
evaluation that put Aruba and competing products through testing
performed by independent laboratories, including Iometrix in San
Francisco and the University of New Hampshire's Interoperability
Lab.
Microsoft was unavailable for comment at press time.
