  1. Mark Johnson mj@ncni.net

  2. Current Organization • Participants • Academic (Duke, UNC, NCSU, WFU) • Industry (Cisco, Nortel, IBM, Alcatel, Time-Warner, Interpath) • Non-profit (MCNC) • Government (NC State Gov) • 6 paid staff • 5 Part-time, 1 Full-Time Administrative Assistant • ~20 Part-time donated local talent

  3. Organization (Cont) • Steering Committee (Layer 8) • Define general strategy • Monthly meetings • Engineering Committee • Make general engineering decisions • Coordinate implementation

  4. Grant Support • Research Triangle Foundation Grant • $2.74 Million over 3 years • Primarily for personnel • NSF HPNS Grant • ~$1.6 Million over 2 years • Network Access (vBNS and Abilene) • IBM SUR Grant (NCSU) • Internet2-specific • Cisco, Fore Systems

  5. Network • Private OC48 ring using Nortel S/DMS ADMs • 5 Sites • Duke, MCNC, NCSU, UNC on ring • Cisco via direct connect • Configured as OC12 ATM • Dark Fiber currently provided by Time-Warner Communications • Soon NCSU Centennial Campus, IBM, Nortel, Interpath

  6. Network

  7. Logical Network Connections

  8. External Connections • SoX (Southern Crossroads) • AUP-Free! • vBNS (DS3) • Abilene (OC12)

  9. Services • MORPHnet model • “Production” and research at each layer • SONET OC3, OC12 • ATM - OC12 • IP - OC3 mesh • Squid cache server • I2 Distributed Storage Server

  10. Measurement • Support the research community • Fully instrumented with OC3mon • 8 X OC3mon on internal links • OC3mon on link to Georgia Tech • FreeB SD/Coral software • Provided by NLANR • UNC faculty-sponsored equipment • Participating in IPPM “Surveyor” project • Basic traffic measurement using MRTG

  11. Network Management • Integrated with NC-REN management • Very simple home-grown tools • “Volunteer” support at campuses • Management of differentiated services?

  12. Applications • Infrastructure • WARP - Web Authentication Resource Protocol • QoS Drivers • IP-based video conferencing • Moderate latency requirement ~250ms • medium bandwidth 5-10Mbps • Voice over IP • Low-Moderate latency • Low bandwidth • Nanomanipulator (Remote microscopy) • Requirement for very low latency <=50ms • Medium-High bandwidth

  13. QoS Suppport • Overprovisioning • Only a partial solution • Not that interesting • Not very scalable • Need Applications drivers

  14. Multicast • DVMRP and PIM Dense support now • PIM Sparse RSN • Important for scalability • Indirect affect on QoS

  15. Future Plans • Add links • IBM (soon) • Nortel • Alcatel • Interpath (in progress) • dWDM • Video and data applications • Packet over light • Upgrade to OC192 and beyond
