METHOD FOR COMPUTING NETWORK REACHABILITY

摘要

A method is provided for computing network reachability in a computer network. The method includes: identifying each of the subnetworks that comprise a computer network; determining, for each pair of subnetworks, data paths between the two subnetworks; for each identified data path, identifying access control lists implemented along a given data path and formulating a diagram that merges reachability sets derived from the access control lists along the given data path; and, deriving, for each pair of subnetworks, a set of network packets that can traverse between the subnetworks from the formulated diagrams.
