What Is StarLight
• Global proving ground in support of grid-intensive
e-Science applications, network performance
measurement, and technology evaluations
• Created specifically to support advanced R&E
requirement (high-speed/colo)
• A layer 2 exchange point in Chicago
• Built with excellent connectivity to existing
carriers and networks
• Located at Northwestern University
• Key site of optical research activities
StarLight Service Description
• StarLight is an exchange point with to national,
regional, federal, and international members
– Physical, switched and routed connectivity
– General policy is not to provide ATM
– ATM available at AADS NAP (direct or from colo router)
• Policy free 802.1q VLANs between networks
• StarLight benefits to connecters:
–
–
–
–
–
High-speed peering with large MTU
Available collocation space
Planned 10GigE
Several US and international networks connected
Multicast support
How To Connect To StarLight
• To connect to StarLight a partner must:
– Contract with a carrier to bring a circuit into the
StarLight facility
– Optionally, rent collocation space
– Logically provision services to other networks at
StarLight across the ethernet switch
• Special offer for FEDnets:
– One GigE from 455 N. Cityfront Plaza to StarLight
• Contributions (est. $15K/GigE) appreciated, 10GigE co-funded
– GigE switching (2yrs service money in the bank)
• Additional VLANs configured upon request
– Peering
• MREN encouraged & transit to STAR TAP for modest traffic
StarLight Carriers
• Currently capable of providing services
– Ameritech – SONET local loops provider
– AT&T – SONET local loop provider
– GlobalCrossing – GigE for SURFnet & AMPATH
– I-WIRE – GigE for regional MREN connections
– Teleglobe – GigE and 2.4G for SURFnet
– Qwest – GigE for DTFnet & NORDUnet OC3
