Internet2 QBone Initiative

The Internet2 QBone Initiative aims to build a scalable and interoperable QoS testbed to support the QoS requirements of tomorrow's applications. This initiative balances networking research with providing a service and builds upon IETF DiffServ work. It also supports intradomain and interdomain deployment of QoS.

  1. Internet2 QBone Initiative SC99Portland, ORNovember 17, 1999

  2. Motivation & Background • Many Internet2 applications requireQoS • Despite years of IntServ/RSVP work, scalable & interoperable QoS is not here! • Internet2 QoS Working Group wrestled with this and... • Launched QBone initiative to: • Build a QoS testbed and iterate as we learn • Balance networking research with providing a service • Build upon IETF DiffServ work • Support intradomain & interdomain deployment

  3. Latency, Throughput, Jitter, etc Adaptive Intolerant Tolerant Application QoS Requirements • Q: What services do tomorrow’s applications need? • A: There are really a broad range of needs • Need better understanding through experience

  5. “Typical” Internet2 Performance East Coast University to West Coast DOE Lab • Minimum Delay • 50th Percentile Delay • 90th Percentile Delay

  6. QBone Architecture • IETF “Diff” + QBone “Serv” • Diff: Expedited Forwarding (EF) (RFC 2598) • Serv: QBone Premium Service (QPS) • Contract: leased line emulation at a specified peak rate • Near-zero loss • Low, bounded jitter • Reservation Setup Protocol • Phase0: long-lived, manual setup, campus-to-campus extent • Phase1: more dynamic, automatic setup, flexible extent • QBone Measurement Architecture • Uniform collection of QoS metrics • Uniform dissemination interface

  8. Recent Activities • QBone architecture (v1.0) finalized • QBone BB Advisory Council (QBBAC) draft recommendations on web site • Interdomain QPS demonstrated (nM demo) • UCAID participation in DOE/NGI testbed (instrumentation, consultation) • QCon router interoperability event • BBop bandwidth broker operability event

  9. QBone BB Group (QBBAC) • Chartered to recommend inter-BB signaling experiment • Numerous R&E and corporate partners • 6 proto-BBs recently tested at BBop: • Merit • U. Kansas • Siemens • Requirements/protocol draft on web site • Converging on recommendation; top contenders: • Lightweight, flexible setup protocol • Int-over-Diff • Luleå Tech. / Telia Research • Globus GARA Scheduler • MCI Worldcom

  10. Abilene QBone Plans • The Plan: • Abilene aggressively implementing QBone architecture • The Status: • Testing GSR edge card functionality (CAR) • Deploying new GSR core cards (MDRR) • Pursuing QBone peerings with ESNet, Dante • Phased rollout starting “real soon” • The Team: • UCAID • Indiana U. • I-TEC • North Carolina • Ohio • NCNE • Cisco • Qwest • Nortel
