State of the Network 2012

Bandwidth

Florida Atlantic University has a core network located on the Boca Raton campus.  The network core utilizes a group of Cisco Catalyst 6500 LAN routers interconnected at 10 Gigabits per second.  Almost all buildings are connected to the network core with multi-Gigabit single-mode fiber connections.

Florida Atlantic University is an equity member in the Florida Lambda Rail (FLR).  FLR offers network connectivity the Internet2 Network, the NLR networking infrastructure, and the Internet with a 10 Gigabit connection on the Boca Raton Campus and a 1 Gigabit connection on the Ft. Lauderdale campus.  External bandwidth averages 1.4 Gigabits per second during the 2012 spring semester.  (figure 1)

Infrastructure Upgrades and Improvements

Twenty-two (22) new Cisco switches were installed on the Boca Raton, Davie, and Jupiter campuses during 2011-2012 as part of the switch replacement project.  OIT continues to make a considerable investment in the switch refresh project that began in 2008.  The switch upgrade project also incorporates new single mode fiber and electrical upgrades in every building.  This exceeds the annual goal of 10 devices per year as part of the five year switch replacement project.  Every network upgrade helps to bring technology in line to support the increasing demand for voice over IP, video, research computing and other bandwidth-rich applications.

Twenty-seven (27) new switch locations were added as a result of several new buildings on the Boca Raton and Harbor Branch campuses.  These buildings were FAU’s new Stadium, the Innovation Village Apartments, and HBOI Research Lab II. 

A total of 49 new switches installed in 2011-2012 accounts for 12.7 % of the network switches.  This raises the number of switches on campus to a total of 385. (figure 2)

Two new Checkpoint firewalls clusters were added to the network in 2012.  The new Checkpoint firewalls offer 10 Gig throughput in addition to intrusion prevention and application filtering technology.

Wireless Network

The FAU wireless network continues to expand on the Cisco controller based platform.  Approximately 325 new 802.11-N access points were installed as part of the new FAU Stadium and the Innovation Village Apartments.  New 802.11-N access points are installed throughout the year as the demand increases for wireless network coverage.  There are a total of 562 [802.11-G] and 1073 [802.11-N] access points installed at FAU for a total of 1635 devices. (figure 3)

The number of wireless devices continues to expand rapidly across the FAU student, faculty, and staff population.  During the 2012 spring semester, the wireless client count exceeded 13,000 users. (figure 4)

Network Growth

As the university network expands with new wired and wireless locations, the average daily hosts on the network increases by approximately 20% per year.  During the spring semester, the average number of daily users exceeded 19,000. (figure 5)  This trend is expected to continue as network driven services and wireless demand continues to increase.
