Exclusivity: Departments at Texas Tech University must utilize Telecommunications Network Design
& Installation Services to design, install, operate, and maintain the networks - cabled
and WiFi - in all buildings. This includes isolated and connected special-purpose
"private" networks as well as building networks that are connected to the TTUnet backbone
and the Internet.
Bandwidth/Throughput Expectations: TTUnet connections (backbone to building, intra-building, and wall outlet) are typically
set to 1 Gbps maximum bandwidth deployed on multi-port switches. Since these multiple
1 Gbps connections share the available bandwidth, the throughput of any given connected
system is expected to be far less than 1 Gbps (e.g., 20-30 Mbps max throughput).
If your needs exceed these expectations, submit a Network Service Request to explore options and determine costs to suit your needs.
Device Requirements: The following requirements must be met by all connected devices:
Must properly function in an Ethernet network.
WiFi devices must support WPA2-Enterprise in order to connect to TTUnet. Exceptions
must be approved by the Director of Enterprise Network Services.
Must accept DHCP network configuration information. Exceptions must be approved
by Telecommunications Network Operations Center prior to connection.
Must comply with all IT Security policies and configuration standards.
University owned computers running Windows, Mac OS, or Linux must be members of the
TTU.EDU Active Directory domain
Shall be kept free of vulnerabilities. The network security vulnerability management
system will periodically scan all devices. Should a vulnerability be reported the
device owner will be given an opportunity to address the issue; should the vulnerability
not be remediated in a timely manner, network access may be removed.
Not Allowed: The following devices MAY NOT be operated at TTU locations without written approval
of the Director of Enterprise Network Services:
Network hubs or repeaters
Network switches or bridges
Network address translators
Wireless (WiFi) access points
WiFi Network Adapter Restriction: In order to preserve WiFi capacity and ensure security, WiFi network adapters may
not be used in fixed devices (i.e., desktops, office equipment, or server systems)
in lieu of cabled connections.
Multicast Not Supported: TTU discourages the use of multicast (e.g., Apple AirPlay or Bonjour, Crestron NVX,
etc.) and does not support its use. Additional network resources are required to
handle this protocol and have been found infeasible in TTU's enterprise network environment.
Multicast has been somewhat successful for wired network devices when limited to the
local area network (LAN). If your system needs involve multicast, it should be tested
prior to purchase and full deployment to ensure feature functionality. Submit a Network Service Request to determine if your needs can be met along with any associated costs.
