| SWITCH LATENCY |
| |
| Summary: This is a performance test suite to measure the time it takes ONOS |
| to recognize a switch going up and down. |
| |
| Pre-requisites: To run out-of-the box this test requires 7 NODES. |
| OC1->OC7 must be set before initiating the test. Passwordless login |
| must be set from TestStation "sdn" root user. The 7 NODES must have |
| their clocks synced to TestStation via ptpd and be accurate to the |
| millisecond. You will also need the Wireshark disector to see openflow packets. |
| |
| *** If you wish to run this test with less than 7 nodes the following |
| alterations must be made: |
| |
| NOTE: Only scale sizes 1,3,5 and 7 will be functional |
| |
| Modifying .params file: |
| -- Remove any values in the comma separated list in the |
| <scale> tag that are above your desired cluster size. |
| |
| -- Remove one instance of “1,2” from the <testcases> tag for each |
| value you removed from <scale> (case 1 and 2 are each called once |
| for each scale value) |
| |
| -- Change the value in the <max> tag to your desired scale size (1,3,5) |
| |
| Modifying .topo file: |
| -- Change the <ONOSbench/COMPONENTS/nodes> tag to your |
| desired scale size |
| |
| -- Remove all unneeded <ONOS#cli> tags and their contents |
