Abstract: A network state is verified in real-time by precomputing a data structure representing header spaces of data packets in respective equivalence classes (ECs) in a first snapshot of the network and in a second snapshot of the network at a later time. The data structure includes respective bitmaps indicating for each data packet forwarding rule for each node in the network a forwarding action to be taken for each EC in the network.
