Are you asking if you can (for example) use the TCP payload to discriminate packets within the switch (that is, as part of a flow match)? If so, the answer is no -- OpenFlow currently provides no capabilities for this. Check out the OpenFlow specifications (e.g., tables 2 and 3 in the OpenFlow 1.0 spec) for information on things that you CAN match on. (I'm not entirely sure I'm understanding the question, though -- feel free to give some clarification about exactly what you want to do.) -- Murphy
