Detailed Description

OpenFlow v1.0, 1.2 and 1.3.2 flow table abstraction.

Author: Marc Sune<marc.sune (at) bisdn.de>, Tobias Jungel<tobias.jungel (at) bisdn.de>

The of1x_flow_table structure contains the main abstraction of the a flow entry table (or a flowmod table).

The basic operations which one can perform over a table are:

Add a flow entry
Update flow entries
Remove flow entries

Additionally the table contain the pointer's to the matching algorithm using in this particular table. This is set during switch bootstrap and cannot be changed at runtime.

The matching algorithm, in conjunction with the state of the table can perform a packet lookup operation. The API is defined in the data struct matching_algorithm_functions Just have a look to the matching algorithm subsystem for more information
