| | 7 | = 802.11 Reference Design: Aggregate Throughput Example = |
| | 8 | |
| | 9 | This example of the Experiments Framework uses two WARP v3 nodes, one configured as an AP, the other as a STA. |
| | 10 | |
| | 11 | The flow of the script is: |
| | 12 | 1. Initialize two WARP v3 nodes |
| | 13 | 1. Ensure nodes are configured as one AP, one STA and that the STA is associated with AP |
| | 14 | 1. Start a fully-backlogged locally generated traffic (LTG) flow from AP -> STA |
| | 15 | 1. For each WLAN rate: |
| | 16 | 1. Read current Tx/Rx packet counts at STA |
| | 17 | 1. Wait 10 seconds |
| | 18 | 1. Read current Tx/Rx packet counts at STA again |
| | 19 | 1. Calculate throughput for 10 second window |
| | 20 | 1. Stop the traffic flow |
| | 21 | 1. Print the results |
| | 22 | |
| | 23 | To run this example: |
| | 24 | * Setup wlan_exp (see [wiki:../../GettingStarted Getting Started] for details) |
| | 25 | * Configure two WARP v3 nodes with the 802.11 Reference Design bitstream- one AP, one STA |
| | 26 | * Open a Python shell |
| | 27 | * CD to the '''Python_Reference/Examples''' directory from the expanded 802.11 Reference design archive |
| | 28 | * Run {{{python throughput_two_nodes.py}}} |
| | 29 | |
| | 30 | The script will run for ~80 seconds, then display its results: |
