Dartmouth College Chooses Aruba Networks For Deployment of
Nation's Largest University Wi-Fi System
Massive Infrastructure Upgrade Brings Voice, Video and Data
over Wireless Technology to Thousands of Students and Faculty in
Hundreds of Buildings around Campus
SUNNYVALE, Calif., Feb. 28 /PRNewswire/ -- In one of the world's
largest and most innovative implementations of 802.11 (Wi-Fi)
technology ever, Dartmouth College in Hanover, NH, has selected
Aruba Networks for a massive infrastructure upgrade.
Already underway, Dartmouth is building one of the most advanced
Wi-Fi networks in operation to support next-generation voice, video
and data services to students and faculty throughout its 200
building, 1.5 square mile campus.
Laptop Battery Dartmouth has deployed over 350 Aruba dual-radio 802.11a+b/g
access points and air monitors and 12 Aruba 5000 wireless LAN
switches. Over the next several months, Dartmouth is replacing over
550 Cisco 350 802.11b APs with dual-radio 802.11a+b/g Aruba 70
APs.
What is a Network Interface Card (NIC) The most important PC device is the network interface card (NIC). Each computer on the network, including the servers, is required to have one installed. It is the NIC that provides connectivity between the PC and the network's physical medium, optic cable. Most of the new motherboards available today for PCs and servers have the network interface card integrated with the motherboard. Older computers and some newer computers do not provide onboard network interfaces which will equire a NIC to be added.
Thinkpad "When we installed our first AP, the technology we used was
state-of-the-art, but the state-of-the art has quickly changed. We
needed to change with it, but more importantly, we needed an
architecture that could adapt to change," said Brad Noblet,
director of Technical Services at Dartmouth College. "We are
deploying wireless on such a large-scale that scalability,
performance and
security were non-negotiable
items. Aruba had the only system we found that could reliably
deliver all three."

First, you install Acronis License Server to manage corporate licenses, and the Console to manage the networked computers. The Agent then may be installed locally onto each networked computer, or remotely from the Console window.
Microsoft Dartmouth's Wi-Fi network is being built to support more than
6,000 undergraduate and graduate students and 2,500 faculty and
staff with voice, cable TV and data along with new location
services over an 802.11 infrastructure supported by Aruba wireless
LAN (WLAN) switching technology.
Optimize OS and applications deployment with templates Templates Template includes all saved stages of the deployment process (a master image to create, user accounts, network settings, etc.). Once you have created a template, you can use it in the future for rapid deployment. With Acronis Snap Deploy Management Console you can manage deployment templates (create and save new templates, edit or delete existing ones) without launching the deployment process. All deployment templates you have created are stored on the Acronis OS Deploy Server, so you have to establish connection with OS Deploy Server to manage them.
Laptop Computers Nearly every Dartmouth student owns a personal computer and more
than 9,000 PCs are in use campus wide. According to the college,
approximately 90 percent of new freshman arrive with 802.11-enabled
laptops.
According to the indictment, Jones would steal various IBM and Penguin computer servers from Verisign's warehouse in Virginia and sell them to Johnson. Johnson would then sell the servers to several individuals, who would sometimes place them for sale on eBay. As a result of this scheme, the indictment alleges that Jones and Johnson caused Verisign to lose more than $120, 000 worth of computer equipment. In the indictment, Jones and Johnson are charged in three counts with causing the interstate transportation of stolen property, namely IBM 330 and 335 servers, in violation of 18 U.S.C.

Desktop Computer The Dartmouth project was driven by the need for centralized
wireless management, future-proofed protection and flexible
security options.
Notebooks According to Dartmouth, universal authentication on any port and
the migration to 802.1X for both wired and wireless users were key
factors in the upgrade. "We currently operate an open network but
are moving users to 802.1X," said Noblet. "Aruba lets us do this
quickly and easily from a central location for both wired and
wireless users without impacting the ongoing operation of the
infrastructure. We can now perform different types of
authentication on any port, whether Web-based authentication, VPN
or an 802.1X -- without having to install a variety of equipment to
support each method."
Lenovo Already in use through select parts of the Dartmouth campus,
students use laptops and PDAs equipped with Cisco's soft phone
technology, IP Communicator and instant messaging from Vocera to
communicate over the Wi-Fi network. At any given
time 50 staff or students are
using Vocera IP badges over Wi-Fi within Dartmouth's Thayer
Engineering School. Because Aruba's system combines application
awareness and stateful traffic controls, it can uniquely
identify voice and data traffic coming from the same laptop and
prioritize voice over data to ensure the high quality calls.
Hard Drive Dartmouth is also using Wi-Fi technology to provide streaming
media, cable TV and to push reference materials, such as class
notes or assignments, to students based on time-of-day or physical
location. Dartmouth is replacing its cable TV plant with cable over
Wi-Fi by converting NTSC and digital cable signals to MPEG for
streaming over its 802.11 infrastructure.
Travelstar With voice, video and data running over Wi-Fi, Dartmouth
improves its ability to quickly provide multi-media services to
students and faculty wherever they are and reduces capital and
operational costs from physical cabling changes that must be
made.
Gateway Dartmouth found the management and upgrading of legacy APs was
costly and cumbersome. "We wanted to increase performance,
centralize management and support new voice and video services over
a dual-band 802.11a+b/g infrastructure," said Noblet. "Aruba gave
us 802.11a and b/g support in APs that can be managed from a single
point. It also delivered a central point for all security and RF
visibility and management that we didn't have with our existing
wireless system."
Laptop Parts The Aruba Difference
Software "Our vision of convergence required a new, centralized model for
wireless that delivers vastly improved performance, automated
management and support for latency-sensitive applications," said
Noblet. "Aruba's wireless system is ideally suited, for handling
voice, video and data applications on a large scale -- and all
managed from a central point."
Hard Drives According to Noblet, several factors were key in Dartmouth's
decision to standardize on Aruba's wireless LAN switching system.
They included:
Electronics -- The ability to support hundreds of APs on a single
system
-- Gigabits of encrypted throughput
-- Low-latency (under 10 milliseconds) handoffs between APs
-- Superior mobility
-- Advanced call admission control mechanisms
-- The ability to classify and prioritize different traffic flows
such as
SIP, H.323 and RTSP
Canon
Only Aruba is able to classify and prioritize different traffic
flows, such as voice and data originating from a single VoIP phone,
and maintain the state of each traffic flow. Advanced tagging and
queuing techniques in Aruba switches and APs allow delay-sensitive
applications to be prioritized over the air and through the wired
network.
