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
