Transcript

  • 1. Louisiana’s Interactive & Collaborative Research Network Kenneth Tanner Network Coordinator LSU Health Sciences Center – Shreveport
  • 2. The network is comprised of …
    • 12 Higher Educational Institutions,
    • 72 H.323 Endpoints,
    • 13 Gatekeepers,
    • MCU,
    • Data Collaboration Tool, and
    • Use Internet 2 as backbone.
  • 3. In the beginning, ….
    • NSF Grant:
      • 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. 2000.
      • Objective: Create an H.323 network for Louisiana’s researchers so they can participate in inter-institutional scientific sharing and strategic planning sessions
      • Principal Investigators
        • Dr. Lee Bairnsfather, LSUHSC-S
        • Dr. Jerry Draayer, LSU
        • Dr. Steve Landry, Univ. of Louisiana at Lafayette
  • 4. Grant Partners/Network Members:
    • Louisiana Board of Regents,
    • Louisiana State University,
    • LSU Agricultural Center,
    • LSU Health Sciences Center - Shreveport,
    • Louisiana Tech University,
    • Northwestern State University,
    • Southeastern Louisiana University,
    • Southern University,
    • Tulane University,
    • University of Louisiana at Lafayette,
    • University of Louisiana at Monroe, and
    • University of New Orleans
  • 5. Equipment Selection:
    • Based on Pilot H.323 Network
      • Grant to evaluate different vendor equipment.
    • 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.
    • Decided on PolyCom endpoints, Radvision gatekeeper, and Accord MCU.
  • 6. Institution Equipment: 1 - Radvision ECS-100 Gatekeeper 1 - PolyCom Viewstation 128 5 - PolyCom ViaVideo LAN
  • 7. Dial Schemes:
    • Support two dial schemes:
      • VideNet & La. dial scheme.
    • La. Dial Scheme
      • Based on “telephone” dial structure
      • Example number: 13186754645
      • Zone Prefix: 1318675
      • Local Extension: 4645
      • Identical to person/room telephone number
    • VideNet number: 02447550509094645
      • Exit Zone Prefix: 0
      • Zone Prefix: 244755050909
      • Local Extension: 4645
  • 8. Gatekeeper Network (La. Dial Scheme): Example Dial String: 13186754645 (Kenneth’s telephone number) Zone Prefix: 1318675 Local Extension: 4645
  • 9. Gatekeeper Network (VideNet): Example Dial String: 02447550509094645 Exit Zone Prefix: 0 Zone Prefix: 244755050909 Local Extension: 4645
  • 10. Gatekeeper Network Summary:
  • 11. Gatekeeper Network (ECS View):
  • 12. Future Statewide Gatekeeper Configuration:
    • Move from Meshed to Redundant Hierarchical Configuration
  • 13. Shared Tools:
    • PolyCom MGC-100 (MCU)
    • PolyCom WebOffice (Data Collaboration Tool)
  • 14. MCU Hub:
  • 15. Backbone:
    • Internet 2 used
    • Later called LearNet within Louisiana
  • 16. LearNet (not LeerNet) Note: Tulane Univ. is not connected to LearNet.
  • 17. Network Management:
    • PolyCom GMS 2.5
  • 18. Participation:
    • Network Services Staff
      • Manage gatekeepers
      • Provided a ViaVideo,
      • By product
        • H.323 experience,
        • Better relate to end user issues, and
        • Provides feedback on condition of network.
  • 19. Participation:
    • End Users
      • Researchers
        • Overall usage low (ramping up)
      • Feedback:
        • Ease of Use
        • What other capabilities do they need?
        • Quality/Reliability vs. H.320
      • Maintaining Address Book/Directory Services
  • 20. Ongoing Activities – Security:
    • Firewalls/NAT
      • PolyCom/Accord Firewall Solution
      • Radvision/Ridgeway
      • Cisco
      • Proxy
      • Personal/Desktop Firewall Solutions
  • 21. Ongoing Activities – Networking:
    • Networking Modes:
      • DSL
      • Cable Modem
      • Frame Relay
      • Satellite
      • Microwave
      • RF
      • T1 or Fractional T1
    • QoS vs. Adding Bandwidth
  • 22. Ongoing Activities – Data Collaboration

    • Have other governmental agencies join.
  • 26. Future Plans
    • Statewide Dialing Directory & MCU Calendar.
  • 27. Future Plans
    • Integration of H.323 VC and VoIP
    IP Network
  • 28. Experience:
    • Technology is the easy part (exception – Firewall & QoS).
    • Difficulties include:
      • Motivating some institutions to bring equipment online (gatekeeper),
      • Distribute equipment to the end user and to those who WILL USE IT!
      • Tell us they have distributed the Systems and provide us with contact information.
      • Working with LEC to get LearNet/Internet 2 access to some campuses.
      • Convincing people to keep desktop units ON.
  • 29. Web Page:

    • User’s Guide
    • Contact List
    • Dialing Directory
  • 30. In closing A unique learning experience I encountered a few months ago….
  • 31. Lesson Learned:
    • Be careful how you configure your end user’s H.323 systems. You never know what you might be EXPOSING your users to.
