Test Execution

Assumptions:

  • pgeni.gpolab.bbn.com or GENI Portal credential are used for tests in this page.
  • Some end-points exist in multiple test cases, so their measurements will be not be duplicated.

Notes:

  • Stitcher currently does not support AM API v3, is delivered to run AM API V2.
  • Capacity must be specified for scenarios where Utah IG is end-point.

Measurements Goals

The set of GENI Network Stitching (GNS) test topologies selected to validate stitching experiment scenarios are also used to benchmark measurements to characterize various areas including setup timing, tear down timing, timing for an experiment to change data paths from one stitched VLAN to another, end-host to end-host data flow set up timing and delay. Throughput will also be measured with iperf between endpoint hosts using the following methodology:

  • All results are captured for default bandwidth allocation, unless otherwise stated.
  • All results are for a 60 second test runs.
  • TCP iperf measurements are collected for:
    • '1 client' scenario using command: 'iperf -c dest_host -t 60'
    • '5 clients' scenario using command: 'iperf -c dest_host -t 60 -P 5'
    • '10 clients' scenario command: 'iperf -c dest_host -t 60 -P 10'
  • UDP iperf measurements are run for 10 seconds increments to determine bandwidth supported
