Abstract
A method of diagnosing a software-defined network is provided. The method determines an observed plurality of network control events from a set of network control event messages. Each network control event message includes a unique identifier and is used for configuring a network configuration entity on a network component. The method, from a description of an expected configuration of the network, determines an expected plurality of network control events. The method backtraces the observed control events from the current configuration of the network to determine whether the expected network control events have occurred. The method identifies a network component as the source of fault when the network component receives an input set of network control events that matches a set of expected network events but does not produce a set of output network control events that match a set of network control events.
