Extending the switch

The following is a brief description of how the switch can be extended with additional functionality, by using the experimenter features of OpenFlow.

Overview

In the current implementation OpenFlow control channel processing is done in two distinct steps: first the wire format is converted to an internal representation (with syntax checking), and then this internal representation is interpreted by the soft switch code. The other direction is handled in a similar manner: the switch code generates a message in an internal representation, which is then converted into OpenFlow wire format.
