  1. Potential Gigapop Philosophies • “Meet-me” point: We provide a switch and air conditioning, you provide everything else. “Bandwidth” is strictly local. • “Bandwidth Collective” - Gigapop purchases circuits to providers and then re-sells them to collective members at cost.

  2. Our Gigapop Philosophy • Bandwidth Collective++ - As above, but Gigapop also provides services such as DNS, caching, network management, fault management, security, training.

  3. So what’s the difference? • How does this differ from a commercial ISP? • Profit is not our motive. Cost-sharing and taking advantage of economies of scale are. • Committed to deploying advanced services such as multicast, IPv6, PKI, VoIP, and QoS/DiffServ. • Spreading the gospel that “high bandwidth” alone is not “high performance.”

  4. The Research -> Production Path • Leverage work done by NLANR Engineering Services (NCNE) and Internet2. • Production network is two floors above NLANR test lab. • Technology transfer works both ways. • They provide us with solutions. We provide them with more problems. This makes us both happy.

  5. Technology Independent Concerns • Above all, do no harm. • The danger of deploying more modern (!) implementations of services that may conflict with the existing implementations.

  6. Technology Independent Concerns • Allocation/Accounting/Billing • Admission control • Privacy/Security • Performance

  7. Multicast Issues • appropriate architecture for different campus types • multi-homed? (I1, multi-I1, I2, multi-I2) • policy routing • existing DVMRP tunnels? • migrating existing multicast arch. to MBGP,MSDP,PIM-SM triad

  8. Multicast Issues • Who should participate in the multicast environment? • Students • Researchers • Administrators • Connected classrooms • Campus switched environment

  9. Multicast Issues • There are problems with multicast applications: • Inadequate representation on Windows. • Using them is about as much fun as driving in Washington, D.C. during the NATO summit. • It would be nice to see some more non A/V multicast applications. • mFTP • software distribution / computer lab management.

  10. Multicast Issues • Until demand is created, multicast deployment on the campus will proceed too slowly.

  11. QoS & diff-serv • Don't create bandwidth • Just carve up existing bandwidth according to some established policy. • Bandwidth broker • very early in development. • certainly not anything close to campus wide.

  12. IPv6 • Ongoing development, both within the GigaPop and to the campuses.

  13. Caching • Requires changes to client applications. • Dynamic pages can’t be cached. • Improves latency • Reduces bandwidth requirements

  14. VoIP • Some long distance cost savings • Once the infrastructure is there, dial plans are everything. • Traditionally manually administered. • How can the GigaPops help?
