  1. Rollout of H.323 Videoconferencing Service Linda Roos OARnet

  2. Today’s Session • Videoconferencing in Ohio • Resources available • Avoiding the Blame Game • Issues to be resolved

  3. Videoconferencing in Ohio • 87 Colleges and Universities in Ohio • Only H.323 • No plans for AGN or mpeg-2 • Testing in 2001 • Service initiated on January 1, 2002 • $960/year • Evolving process • Streaming a possibility

  4. Resources • Full-time engineering staff • NOC staff • ITEC-Ohio staff • Ohio State staff

  5. OARnet’s Advantage • ITEC-Ohio • H.323 Beacon • Used to qualify an H.323 videoconference • No manual intervention necessary • Existing tools expensive

  6. OARnet’s Advantage • Bob Dixon • Internet2 Commons second level support • Largest concentration of MCUs in world

  7. MCUs at OARnet/Ohio State • OARnet MCUs • Internet2 MCUs

  8. OARnet MCUs • Two Accord MGC100 MCUs • Each allows about 60 H.323 connections • One allows voice calls • One also allows ATM and ISDN connections • Three RadVision OnLan MCUs • Each has nine ports

  9. Internet2 MCUs • Accord MCG100 • 60 H.323 connections • RadVision Via IP • 50 H.323 connections • Gatekeeper built in • Six RadVision OnLan • 9 ports each

  10. Avoiding the Blame Game • Register • Site Coordinator Certification • Schedule Videoconference • Test, test, test • Conference

  11. Avoiding the Blame Game • Certified site coordinators • Mirrors Internet2 Commons effort • Offer bi-monthly classes • Self-certification possible • Must test to complete certification • Becomes a “Let’s Fix the Problem” Game • Class provides ideas on what can go wrong in local network

  12. Upcoming Workshops • Introduction to Videoconferencing February 27, 2002 $150.00 • Videoconferencing Certification Class March 26 and 27, 2002 $150.00 • Contact Julie Miller (jmiller@oar.net)

  13. Avoiding the Blame Game • Firewalls a problem • NAT a problem • Switched 10 mb ethernet • Full duplex • Mismatch of full and half duplex problematic • Older Polycom equipment (half duplex) • Cabling is important • CAT-5 is not always CAT-5 • CAT-5 enhanced or CAT-6 • Buy best cable available

  14. Avoiding the Blame Game • Adequate resources to do what you need to do • Personnel • Funding • Equipment • Transition from ATM to IP can be expensive • Staff training • Equipment Upgrades

  15. Issues to be Resolved • Dialing plan • Automated scheduling

  16. Dialing Plan • Currently do not have one • Evolving as videoconferencing world becomes more complex • Will be following VideNet plan • Started with decentralized plan • Every gatekeeper knew all • Hierarchical model (DNS-like)

  17. Automated Scheduling • Currently manual • Support Center • Internet2 Commons • Investigating Products • Expensive • Most only work with particular MCU • Algorithms could be complicated • Can run out of one resource before another • Some human intervention necessary
