Network Services is responsible for managing a complex network that spans the Knoxville campus and remote sites scattered around the region. Network Services’ responsibilities include the management of the local UTK network (both wired and wireless), a range of wide area connections, and Internet/Internet2 connectivity. In addition, the group manages various security devices such as firewalls, VPN (Virtual Private Network) access devices, IPS devices (Intrusion Prevention Systems).
- Local Area Network (LAN):At its core, the UTK network is fully redundant with multiple 10 Gbps links connecting core nodes and several high profile buildings on campus. At this time, the majority of the campus buildings connect at 1 Gbps. Overall, the campus network supports approximately:
- Wireless Access: A state of the art wireless network consisting of more than 4,500 wireless access points (APs) spans the entire campus. A major upgrade to the wireless infrastructure was completed in the summer of 2009.
- Wide Area Network (WAN):Remote offices are linked to the main campus network using connections ranging from 1.5 to 100 Mbps. Such locations include offices in Knoxville, Oak Ridge, Nashville, and Agriculture Extension facilities at various locations in Tennessee.
- Internet Connectivity:Multiple, redundant connections provide the UTK community with access to the Internet at an aggregate speed of more than 1.25 Gbps (fall of 2012).
- Research Network: Multi-Gbps network connecting UTK to research facilities in ORNL (Kraken supercomputer), Fermi Labs in Chicago, and Internet 2 sites via Southern Crossroads (http://www.sox.net).
- Internet 2® Connectivity:UTK is a Sponsored Education Group Participant (SEGP), a program that allows us to sponsor other educational institutions’ access to Internet2 resources.
41,000 FastEthernet connections (max. 100 Mbps),
13,500 Gigabit Ethernet connections (max. 1000 Mbps), and
450 Ten Gigabit Ethernet connections (max. 10,000 Mbps)
- Firewalls:Two core firewalls and a multitude of smaller, department-size firewalls, are deployed and managed by Network Services.
- Secure remote accessis facilitated through VPN access devices (appliances) that support both IPSec and SSL/VPN access.
- Intrusion Prevention Systems (IPS)are deployed at strategic locations on the network in order to provide an additional layer of security and compliance for the campus community.
