| 2 | OpenFlow Test Framework |
| 3 | |
| 4 | Configuration fragment |
| 5 | |
| 6 | This file contains Python code to specify the configuration |
| 7 | of the system under test. |
| 8 | |
| 9 | This is a work in progress. The code below is for illustration only. |
| 10 | |
| 11 | The configuration information is extensible in that any |
| 12 | Python code may be added to this file (or its imports) and will |
| 13 | be available to test cases. |
| 14 | |
| 15 | A platform identifier is given at the top of the file and most |
| 16 | other information is determined by testing this value. Additional |
| 17 | files may also be imported based on the platform. |
| 18 | |
| 19 | The configuration must specify a mapping from system interfaces |
| 20 | available to the test framework to OpenFlow port numbers on the |
| 21 | switch under test. This is done in the interface_ofport_map |
| 22 | dictionary. Future extensions may include specifying a driver |
| 23 | for the port (so as to allow remote packet generation) and to |
| 24 | specify a switch instance (to allow multiple switches to be |
| 25 | tested together). |
| 26 | |
| 27 | Currently, the assumption is that ports are bidirectional, so |
| 28 | specifying "OF port 1 is connnected to eth2" implies this is so |
| 29 | for both TX and RX. |
