TTVN (formerly known as the Trans-Texas Videoconference Network) is the wide area data and interactive communications network that serves the campuses and agencies of The Texas A&M University System. The network also serves a number of affiliated colleges and universities, K-12 school districts, and state agencies throughout Texas. The core TTVN network consists of over 100 primary wide area network sites and more than 250 videoconference sites.
TTVN provides enterprise-class commodity internet, Internet2, and Texas Intranet data services to all members of the Texas A&M System and the extended TTVN community. TTVN also provides videoconference scheduling and support, high capacity multi-point videoconference bridging, and live video streaming services for classes, meetings and special events.
The TTVN backbone network infrastructure is an all internet protocol (IP) environment. The IP environment allows TTVN staff to focus on a single type of network infrastructure for all supported services. This allows the most cost-effective environment and the most efficient utilization of bandwidth. The TTVN network is monitored 24/7/365 with the ultimate goal of providing 99.999% reliability.
The TTVN network is part of the Lonestar Education and Research Network (LEARN). LEARN is a carrier-class optical network between Texas cities operating on twenty-year IRU leases of dark fiber optic circuits. Multiple gigabit ethernet, 10-gigabit ethernet, and SONET optical paths operate between Dallas, College Station, Houston, Austin, San Antonio, and back to Dallas to form the highly reliable LEARN ring architecture. LEARN is a partnership of 33 Texas higher education institutions.
TTVN and LEARN provide connectivity to the Internet2 NewNet backbone through multiple redundant gigabit ethernet connections. These connections, in cooperation with the University of Texas System Office of Telecommunications Services (UT-OTS), serve as the Texas higher education access points to Internet2. The Internet2 network backbone also provides TTVN with international connectivity to the Texas A&M University campus in Doha, Qatar and to Texas A&M facilities in Mexico City and Costa Rica.
TTVN provides videoconference technical support, high capacity multi-point videoconference bridging, ISDN / H.320 gateways, live and recorded video streaming, and videoconference equipment maintenance. Multiple Multipoint Control Units (MCUs) that are scheduled and operated by TTVN provide highly flexible, multi-point bridging and gateway videoconference services. TTVN videoconference and live video streaming services are available to Texas A&M System users at no per user or per event cost.
TTVN is managed and operated for the Texas A&M System by the staff of the Texas A&M University Division of Information Technology.
