GENI Racks Performance

This page captures performance measurements for GENI Racks using OpenFlow and Stitching Scenarios. The following topologies will be used with raw-pc/bare metal dedicated hosts:

  • Site Confirmations test for multi-site OpenFlow connections over Meso-scale:
    • New IG Site to GPO IG, GPO EG, Utah PG
    • New EG Site to GPO IG, GPO EG, Utah PG
  • Site Confirmations test for OpenFlow connection over AL2S:
    • New IG Site to GPO IG, GPO EG, Utah PG
    • New EG Site to GPO IG, GPO EG, Utah PG
  • Site Stitching Confirmation test via stitched VLAN:
    • New IG Site to GPO IG
    • New IG Site to GPO EG Bare Metal
    • New EG Site to GPO IG
    • New EG Site to GPO EG Bare Metal

Test Methodology

Test Characteristics:

  • All test hosts are dedicate hosts (bare metal/raw-pc)
  • All results are captured for default bandwidth allocation (100Mb/s shaped), unless otherwise stated.
  • All results collected between 2014-01-xxx and xxx???

Iperf TCP measurements captured in this page have the following assumptions:

  • All results are for a 60 second test run.
  • for OpenFlow scenarios, traffic is exchanged to establish data flows before measurement test runs are executed.
  • iperf '1 client' scenario command: 'iperf -c dest_host -t 60'
  • iperf '5 clients' scenario command: 'iperf -c dest_host -t 60 -P 5'
  • iperf '10 clients' scenario command: 'iperf -c dest_host -t 60 -P 10'

Iperf UDP measurements captured in this page have the following assumptions:

  • Each test run is 60 seconds.
  • UDP measurements between racks requested a bandwidth of 100 Mbits/sec, if results showed that 100Mb/s was possible, then increased to 1Gb/s.
  • UDP measurements within a rack requested a bandwidth of 1Gbits/sec for test run

Historical Data

Various effort have captured performance for GENI Racks, following is a list of earlier pages that have capture some aspect of performance with OpenVZ, Xen and dedicated hosts. These pages should be considered obsolete:
