Detailed Description

Bind together a set of IO classes in order to form a virtual subnet for testing, one instance per subnet.

[virtual]

Receive frames

All frames generated by an OLSR instance arrive here. Note that a frame arriving from one OLSR instance is not sent directly to another. The frames are queued and only when OLSR instance gives back control to the eventloop are the frames forwarded. This ensures that two OLSR instances are not in each others call graphs, which can cause re-entrancy problems.

[virtual]

Bind an interface to the emulated subnet.

Unbind an interface from the emulated subnet.
