1. Internet2 QBone Initiative SC99 Portland, OR November 17, 1999

2. Supercomputing ‘99 — Portland, OR, November 16, 1999 Motivation & Background n Many Internet2 applications require QoS n Despite years of IntServ/RSVP work, scalable & interoperable QoS is not here! n Internet2 QoS Working Group wrestled with this and... n 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. Supercomputing ‘99 — Portland, OR, November 16, 1999 Application QoS Requirements Intolerant Tolerant Adaptive Latency, Throughput, Jitter, etc n Q: What services do tomorrow’s applications need? n A: There are really a broad range of needs n Need better understanding through experience
