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
