Abstract

A trace packet can be used for path analysis in a software defined network (SDN). The trace packet can be generated with a source address matching a source address of an existing flow, a destination address matching a destination address of the existing flow, and a unique identifier (UID). The trace packet can be injected into a network via a specified port of a network device along a programmed path of the existing flow. An observation post (a defined network device along the programmed path of the exiting flow) can be instructed to send any packet that includes the UID to a network controller for path analysis.
