Abstract
A method for implementing Ethernet operation, administration, and management (OAM) function in a network element coupled to a software-defined networking (SDN) system is disclosed. The method comprises adding a flow table entry for an OAM traffic flow to a flow table of the network element. The method continues with adding a group table entry for the OAM traffic flow to a group table of the network element, where the group table entry includes an instruction to send the packet to a set of ports, including a loopback port. The method continues with receiving the packet directing to the group table entry from the SDN controller, and sending the packet to the set of ports of the network element according to the group table entry, where the packet is to be looped back through the loopback port to the flow table periodically at a predetermined interval.
