Hi Bernd In order to realize that, there is a thing called "Wildcard".
The OpenFlow specification v1.0 at "5.2.3 Flow Match Structures" helps you. Concretely you can do as follows. I will assume that you create a component in C/C++. You would fill a ofp_flow_mod object when you install a flow into swtich. To detect ANY value at tcp_source, you should set following value at wildcards variable of ofp_match object which combined in ofp_flow_mod object (see include/openflow/openflow/openflow.h). ofm->match.wildcards = 0; ofm->match.wildcards |= htonl(OFPFW_TP_SRC); And following statement is needed to be interpreted as a tcp/ip microflow. ofm->match.nw_proto = IP_TYPE_TCP; I hope you will find it helpful.
