Abstract
A network verification method may include identifying a data plane including one or more forwarding tables for each switch of a plurality of switches in the data plane. The method may also include generating a forwarding behavior representation of the data plane to represent Boolean combinations of forwarding rules of the one or more forwarding tables of the data plane. Further, the method may include comparing the forwarding behavior representation of the data plane to one or more network properties to detect one or more errors in the data plane.
