This provides a simple wrapper for Click software switches in the Mininet network virtualization environment.
Currently it allows for Click kernel switches to be run as a virtual switch. While this is a functional wrapper around Click, there are some important limitations:
- Only one Click configuration may be used
- Path to the configuration file must be hard-coded into the class
- You must manually map network interfaces in the Click config file to hosts connected to the switch
- I have not tested it with multiple Click switches yet
Please see the test.py and sandbox.py files for examples. Both construct a
simple topology of two hosts connected by a single switch:
Host 1 <--> Click router <--> Host 2
The router configuration just connects the two hosts together and passes on
traffic between them. Running test.py will set up the network and then use
netcat and wget to retrieve a file from Host 1 to Host 2.
The sandbox replicates the same network topology and then drops into the Mininet command line interface.
