Utah Education Network - Interactive Video Conferencing (IVC)
Internet, WAN, & IVC Three key services UEN provides to it’s stakeholders. • Internet access and research network access via the Front-Range Gigapop, Nat’l Lambda Rail, & I2 • Backbone and WAN connectivity for all higher education, school district offices, secondary schools, and many city & county libraries. • Statewide IVC network connecting 400 higher education and public education classrooms.
UEN’s IVC Network • 400 higher education public education classrooms throughout Utah • Seven 48 Port RADVision ViaIP 400 MCUs deployed regionally providing 336 ports at 768K. UEN operates all events at 768K. • Two Codian IPVCRs enabling UEN to record up to 20 conferences/classes at a time. • 1 Tandberg Border Controller for firewall transversal. • UEN launches approximately 1000 events per week.
IVC’s Solid Network Foundation • One of the key elements to UEN’s successful implementation and support of it’s IVC network is the WAN. • Gigabit Ethernet backbone with a ring topology in key regions of the state. • Gigabit to all higher education and most public schools. With a minimum of a dedicated T1 per classroom if broadband is not available.
Technical Support • Two Video Operations Centers providing seamless IVC support from 6:00 AM to 11:00 PM Monday thru Saturday. • UEN Field Operations and Network Operations Center support • UEN Scheduling – Coordinates the scheduling of events statewide. • Works directly with higher education counter parts • Schedules all public education events
Support Challenges • Campus and District Firewalls • Open required ports • Implement secure video VLAN • Firewall transversal appliance • Last resort • Scheduling and management solution for large enterprise.
Next Generation • Setbacks and restarts • First test and implementation of next generation platform unsuccessful. • New evaluation underway of Big 3 contenders • Tandberg/Codian 4200 & 4500 • RADVision Scopia • Polycom RMX
NextGen Requirements • Carrier Class • N+1 configuration • Hot-standby or load balanced management servers • Redundancy when possible • 99.99% Reliability – May be a challenge for venders • Scaleable – Enterprise solution • MCU must support transparent cascading
NextGen Requirements • A portion of the solution must support high-definition. • All high definition solutions must work seamlessly in a standard definition environment. • Solid management suite. • UEN’s approach to video is scheduling intensive and the performance of the management application directly affects the performance of the IVC network as a whole. • Large database • High number of users accessing application entering schedules, changes and deletions.
NextGen Requirements • Desktop solution that supports H.239 • Transcoding • Local control of event to enable manual switching. • Non-Meshed infrastructure – must be able to control each MCU manually if necessary. • Reliability is the most important requirement of all • Scaleable event recording and archiving with access from the desktop and end point.
