1 Louisianas Interactive & Collaborative Research Network Kenneth Tanner Network Coordinator LSU Health Sciences Center – Shreveport

2 The network is comprised of … 12 Higher Educational Institutions, 12 Higher Educational Institutions, 72 H.323 Endpoints, 72 H.323 Endpoints, 13 Gatekeepers, 13 Gatekeepers, MCU, MCU, Data Collaboration Tool, and Data Collaboration Tool, and Use Internet 2 as backbone. Use Internet 2 as backbone.

3 In the beginning, …. NSF Grant: NSF Grant: Title: Video to the Desktop: A Louisiana Model Title: Video to the Desktop: A Louisiana Model Awarded $494,450 with $367,680 being matched for a total of $862,130. Awarded in Aug Awarded $494,450 with $367,680 being matched for a total of $862,130. Awarded in Aug Objective: Create an H.323 network for Louisianas researchers so they can participate in inter-institutional scientific sharing and strategic planning sessions Objective: Create an H.323 network for Louisianas researchers so they can participate in inter-institutional scientific sharing and strategic planning sessions Principal Investigators Principal Investigators Dr. Lee Bairnsfather, LSUHSC-S Dr. Lee Bairnsfather, LSUHSC-S Dr. Jerry Draayer, LSU Dr. Jerry Draayer, LSU Dr. Steve Landry, Univ. of Louisiana at Lafayette Dr. Steve Landry, Univ. of Louisiana at Lafayette

4 Grant Partners/Network Members: 1. Louisiana Board of Regents, 2. Louisiana State University, 3. LSU Agricultural Center, 4. LSU Health Sciences Center - Shreveport, 5. Louisiana Tech University, 6. Northwestern State University, 7. Southeastern Louisiana University, 8. Southern University, 9. Tulane University, 10. University of Louisiana at Lafayette, 11. University of Louisiana at Monroe, and 12. University of New Orleans

5 Equipment Selection: Based on Pilot H.323 Network Based on Pilot H.323 Network Grant to evaluate different vendor equipment. Grant to evaluate different vendor equipment. Some equipment evaluated included OnLAN MCU & Gateway, MCG-100, ViaVideo, Viewstation, Escort 25, Vigo, etc. Some equipment evaluated included OnLAN MCU & Gateway, MCG-100, ViaVideo, Viewstation, Escort 25, Vigo, etc. Took best equipment from Pilot Network & integrate into Production H.323 Network. Took best equipment from Pilot Network & integrate into Production H.323 Network. Decided on PolyCom endpoints, Radvision gatekeeper, and Accord MCU. Decided on PolyCom endpoints, Radvision gatekeeper, and Accord MCU.

6 Institution Equipment: 1 - Radvision ECS-100 Gatekeeper 1 - PolyCom Viewstation PolyCom ViaVideo LAN

7 Dial Schemes: Support two dial schemes: Support two dial schemes: VideNet & La. dial scheme. VideNet & La. dial scheme. La. Dial Scheme La. Dial Scheme Based on telephone dial structure Based on telephone dial structure Example number: Example number: Zone Prefix: Zone Prefix: Local Extension: 4645 Local Extension: 4645 Identical to person/room telephone number Identical to person/room telephone number VideNet number: VideNet number: Exit Zone Prefix: 0 Exit Zone Prefix: 0 Zone Prefix: Zone Prefix: Local Extension: 4645 Local Extension: 4645

8 Gatekeeper Network (La. Dial Scheme): Example Dial String: (Kenneths telephone number) Zone Prefix: Local Extension: 4645

9 Gatekeeper Network (VideNet): Example Dial String: Exit Zone Prefix: 0 Zone Prefix: Local Extension: 4645

10 Gatekeeper Network Summary:

24 Future Plans Seamless connectivity between various independent H.323 networks within state. Seamless connectivity between various independent H.323 networks within state.

25 Future Plans Have other governmental agencies join. Have other governmental agencies join.

26 Future Plans Statewide Dialing Directory & MCU Calendar. Statewide Dialing Directory & MCU Calendar.

27 Future Plans Integration of H.323 VC and VoIP Integration of H.323 VC and VoIP IP Network

28 Experience: Technology is the easy part (exception – Firewall & QoS). Technology is the easy part (exception – Firewall & QoS). Difficulties include: Difficulties include: 1. Motivating some institutions to bring equipment online (gatekeeper), 2. Distribute equipment to the end user and to those who WILL USE IT! 3. Tell us they have distributed the Systems and provide us with contact information. 4. Working with LEC to get LearNet/Internet 2 access to some campuses. 5. Convincing people to keep desktop units ON.

30 In closing A unique learning experience I encountered a few months ago….

31 Lesson Learned: Be careful how you configure your end users H.323 systems. You never know what you might be EXPOSING your users to. Be careful how you configure your end users H.323 systems. You never know what you might be EXPOSING your users to.
