Abstract
A method for path monitoring is disclosed. The method includes receiving, at the network device, a packet from a SDN controller to monitor a path for a service between the network device and another network device. The method includes sending the packet to at least a first and a second port, where a first instance of the packet is transmitted to the first port to the other network device to monitor the path, and a second instance is transmitted to the second port that loops back the second instance to the network device at a transmission interval so that the packet is sent to the first port repetitively at the transmission interval. The method also includes determining whether or not the packet is received from the other network device within a timeout interval and discarding the packet upon determination that the packet is received within the timeout interval.
