1. E2Epi Network Performance Workshops Eric L. Boyd

2. 2 What’s the problem? Diagnosing E2E problems is often: ad hoc time consuming “unfair” / not uniform Example

3. 3 E2Epi Network Performance Workshop Announcement: Internet2 has begun a new series of workshops Focus: Performance Tools BWCTL, OWAMP, NDT Installation Use Integration into IT support process Approach Hands on Interactive

4. 4 Performance Tool Beacons BWCTL / Iperf Throughput tool with resource allocation broker Iperf is a tool developed by NLANR/DAST OWAMP One-way latency tool (one-way ping) NDT First-mile diagnosis of commonly encountered problems

5. 5 Workshop Deliverables Working installation of BWCTL, NDT, and OWAMP at GigaPoP Working installation of BWCTL, NDT, and OWAMP at each campus Exchange of “keys” among campuses and GigaPoP Community of Collaborative approach to performance diagnosis

6. 6 Workshop Host / Audience Each workshop has a host, expected to be a campus / GigaPoP Audience is network engineers from a GigaPoP and associated campuses Host must identify audience, make invitations, provide networking

7. 7 Workshop History Developed/taught by Internet2 PAT Team (Spring ’05) SOX, hosted by GaTech (March ’05) http://e2epi.internet2.edu/network-perf- wk/gatech/agenda.html http://e2epi.internet2.edu/network-perf- wk/gatech/agenda.html CENIC, hosted by UCLA (June ’05) Joint Techs – Vancouver (July ’05) Orthogonal to focus on GigaPoPs Good opportunity to “kick the tires” After that, TBD …

8. 8 What’s Next? The focus of this workshop is on building standalone tool “beacons” for prepositioned on-demand testing. We are currently developing (in conjunction with GÉANT2 JRA1) a measurement framework for: Regularly Scheduled Tests Measurement Point Discovery Alpha participants in measurement framework will be drawn from “deployment footprint”
