I don't understand the question.  OVS can be used like other networking 
switches and placed in arbitrary configurations.  The one limitation is that 
the network cannot contain loops, since OVS does not natively support STP 
(Spanning Tree Protocol).  People have implemented STP and loop prevention 
protocols on OVS using a central controller and OpenFlow, though.
