| SCPFintentRerouteLat |
| - Test Intent Reroute Latency |
| - Test Algorithm: |
| 1. Start Null Provider reroute Topology |
| 2. Using Push-test-intents to push batch size intents from switch 1 to switch 7 |
| 3. Cut the link between switch 3 and switch 4 (the path will reroute to switch 8) |
| 4. Get the topology time stamp |
| 5. Get Intent reroute(Installed) time stamp from each nodes |
| 6. Use the latest intent time stamp subtract topology time stamp |
| - This test will run 5 warm up by default, warm up iteration can be setup in Param file |
| - The intent batch size will default set to 1, 100, and 1000, also can be set in Param file |
| - The unit of the latency result is milliseconds |
