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

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

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

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
