Computer Network Backbone - T&N strives to provide a campus network backbone that meets the needs of the campus today and for several years beyond.

    *Sufficient Bandwidth - The campus backbone is Ten Gigabit Ethernet that allows the use of voice, video, and data.

    *Redundancy - The backbone has redundant links, backup power supplies, and backup servers which fail-over in the event of trouble. While not totally seamless, it does allow for a quick recovery in the event of broken cable, electrical failure, or equipment failure.

    *Integrity - Through the use of additional bandwidth, redundancy, better documentation, and vendor support, the network is very reliable and stable. This allows for unprecedented growth in the number of users and in the complexity of applications using the network.

Security on the Network Perimeter -The University computer network firewall plays a major role in information security. It is important that this appliance restrict access to the protected side of the network as much as possible. Publically accessible services including Web access and FTP are provided outside the firewall from the demilitarized zone (DMZ) only. Exceptions must ensure security and be approved by T&N and the Information Security Office.

Only T&N managed internal firewalls will be allowed to securely connect subnet virtual local area networks (VLANs) within the computer network. The use of personal/server host-based firewall products is encouraged.

All users of the computer network must adhere to the Network Access Policy.

Desktop Connectivity - Each user has a 10Base-T or 100Base-T unshielded twisted pair (UTP) line that connects their desktop device to a switched Ethernet port.

Desktop Network Configuration - There are several parameters that must be set on each desktop to successfully utilize the services offered by the network. Our campus uses Dynamic Host Configuration Protocol (DHCP) to configure most desktops. Those devices that can not be configured for DHCP may be assigned a static IP address.

Wide Area Network (WAN) - T&N provides WAN connectivity to remote sites throughout the San Antonio metro area and South Texas. Services include support for voice, video, and data.
