Internet2 QBone Initiative
SC99Portland, OR
November 17, 1999
Supercomputing ‘99 — Portland, OR, November 16, 1999
Motivation & Background Many Internet2 applications require QoS 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
Supercomputing ‘99 — Portland, OR, November 16, 1999
Application QoS Requirements
Intolerant
Tolerant
Adaptive
Latency, Throughput,Jitter, etc
Q: What services do tomorrow’s applications need? A: There are really a broad range of needs Need better understanding through experience

“Typical” Internet2 Performance
East Coast University to West Coast DOE Lab
• Minimum Delay• 50th Percentile Delay• 90th Percentile Delay
Supercomputing ‘99 — Portland, OR, November 16, 1999
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

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
Supercomputing ‘99 — Portland, OR, November 16, 1999
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
Supercomputing ‘99 — Portland, OR, November 16, 1999
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
