Abstract:
Methods and systems for partially or fully distributed network verification are described. In partially distributed network verification, each network device generates a respective device-level binary decision diagram (BDD) representing the logical behavior of the respective network device for a network property of interest. The device-level BDDs from each network device are received by a verification service that performs verification by generating an input BDD representing an input header space, and applies each device-level BDD in a logical path from a source device to a destination device, and reports the output BDD. In fully distributed network verification, each network device is responsible for calculating a device-specific output BDD by applying a device-specific BDD, which represents the logical behavior of the network device, to a device-specific input BDD.
