UB IT: The Central Computing Organization
UB IT provides centralized computing and
communication services to faculty, staff, and students. Approximately 200 full-
time staff are employed in this division.
Campus Network Infrastructure
The University at Buffalo's
campus network is supported by an extensive fiber
optic infrastructure which extends to all 120 campus buildings across two
campuses.
There are more than 180 fiber-optic-attached Ethernet LANs supporting
more than 18,000 individual connections.
The campus network is composed of a gigabit (Gbps) Ethernet backbone with
gigabit links to buildings. The UBNet edge switch replacement project
underway has upgraded approximately 25% of the communication closets and
results in gigabit desktop connection speeds, an increase from the standard
switched 100-Mbps Ethernet.
The network includes interconnections with several local, regional, and
national networks including the Western New York Health Science Consortiium, NYSERNet,
SUNYNet, Commodity Internet and Internet 2 via Abilene. The campus Internet (I1)
and Internet2 (I2) links have been upgraded to 300 Mbps and 200 Mbps respectively.
UB is a member of the
Northeast LambdaRail (NeLR), a consortium enabling educational
institutions in New York and New England to connect to and support the
National LambdaRail (NLR).
The University has played a leadership role in the community by
bringing together city, county, and state agencies in the
development of a
"dark fiber" (fiber optic) broadband network
infrastructure that
UB has subsidized and made available to local
higher education and K-12 institutions, health care institutions
(hospitals and research institutions), and government organizations.
This regional fiber optic infrastructure connects the campus
to remote research facilities, our regional partners, and commercial points of presence, providing gigabit connections to our research partners and
a backbone for local not-for-profits.
Wireless Access
The University wireless network has become a critical resource for
the UB community, as more and more of our faculty, staff, and
students own and rely on multiple mobile devices, including
WiFi-enabled cell phones, PDAs, laptops,
and MP3 players, for a multitude of services. UB has recently launched
an
mUB (Mobile UB Campus) initiative to provide services and support for
these personal mobile devices.
CIT continues to expand
wireless network access. There are currently 504 wireless access points deployed throughout
the campus.
More than 2500 simultaneous users can be accommodated by our wireless
network.
Some departments also deploy their own wireless access points.
The
UB Wi-Fi expansion is upgrading all existing wireless access points to current
code levels to support
both the Wireless "G" and "A" standards.
In addition, the infrastructure is being converted to a centrally-managed
system which will allow for more efficient maintenance of the large
number of access points deployed.
All residence halls and UB apartments are wired with Ethernet for Internet
connectivity, providing one data connection or port per resident. Most residence
halls and UB-owned apartments provide 100 Mbps desktop connectivity.
Remote Access
UB provides approximately 240 dial-in lines for off-campus access to UB resources
and the Internet: a string supporting the V.90 56Kbps protocol and a digital
string supporting the ISDN protocol. A VPN service provides secure connections
from ISP networks.
Telephones
In the past, voice services have been provided through the distribution and configuration of a
10,000 line Bell Atlantic Intellipath telephone system, supporting over 15,000
stations on numerous key systems. A new
IP-based voice system (VoIP) is now being
deployed.
UB is also partnering with a vendor to reinforce the campus cellular network to
provide better coverage for cell phones.
Enterprise Hardware Platforms
CIT maintains more than 200 SUN servers providing the following campus services:
- directory and authentication
- timesharing
- administrative applications for University business and student service systems
- nameservice
- web hosting
- email
- news
- file storage
- tape backup
An IBM mainframe running the OS/390 operating system also hosts University
business and other administrative applications.
Campus Computing Labs
At present there are more than 2450 personal computers and high performance workstations in
campus labs, run by
CIT, schools, and departments for students. Many labs offer specialty
software for course work and are open 24 hours/day.
General access facilities open
to all students, are being upgraded this summer (2007) to feature more than
600 Dell OptiPlex 745 Minitower: Intel Core 2 Duo Processor (2.13 GHz, 2M, 1066
MHz FSB) running
Windows XP. Two of these public sites are configured as dual boot Linux/Windows
systems.
Instructional Technology Support and Services
UB has 84 centrally-scheduled, state-of-the-art,
high-tech, multimedia classrooms, located on the North and South campuses. The instructors' podiums
provide touch screen control of video and sound systems, and contain computers,
VCR/DVD and projections facilities. Many departmentally-scheduled classrooms
are similarly equipped. In addition, all of UB's centrally-scheduled
classrooms are wired for Internet access. The
Instructional Technology Services Technology Classrooms web page
provides information on the technology equipment found in classrooms
on the North and South campuses. (See the "Classroom Attributes" link for
specific information on a classroom.) Audience Response Systems (Clickers in the Classroom) will be available in all Technology Classrooms by the
end of the 2007-08 Academic Year. More than 20 classrooms will have
Clickers by the start of the Fall, 2007 semester.
Advanced course technology services such as "digital course casting" are
also provided. UB is a leader in state-of-the-art digital course
capture infrastructure and course-casting/streaming, providing
students with audio- and video-recordings of lectures that can
be accessed from student mobile devices, including iPods and other MP3
players and laptops, as well as from desktop systems. Students
access the recordings through our course management system, UBlearns, and
through a UB-branded iTunes U web site.
UB also has an active distance learning program with classrooms (Baldy, Bell,
Abbott)
equipped with real-time distance learning and videoconferencing.
