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

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

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

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

Network

Logical Network Connections

External Connections SoX (Southern Crossroads) –AUP-Free! vBNS (DS3) Abilene (OC12)

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

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

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

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

QoS Suppport Overprovisioning –Only a partial solution –Not that interesting –Not very scalable Need Applications drivers

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

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