Abstract
An electronic device includes a processor and a memory coupled to the processor and storing computer readable program code that when executed by the processor causes the processor to perform operations including generating, at given time intervals, a plurality of topology graphs that correspond to a service chain that comprises a plurality of virtual network functions (VNFs) and that is operating in a software defined network (SDN)/network function virtualization (NFV) computing environment, each of the plurality of topology graphs corresponding to a different one of the time intervals. Operations may include comparing a first one of the plurality of topology graphs that is received at a first time to a second one of the plurality of topology graphs that is received at a second time that is after the first time to determine if the service chain has a fault.
