It is describe a novel Routing algorithm developed for Software Defined Network WAN. The Algorithm Called Shortest Feasible OpenFlow (SFOP) because it is use the OpenFlow interface statistics to compute the path.

OpenFlow fields:
• OpenFlow specification introduced new match fields including
Ethernet, IPv4/v6, MPLS, TCP/UDP, etc.
• Only a subset of those matching fields are mandatory
