Abstract

In a network packet router having one or more ingress and egress ports, a method is implemented at an ingress port for egress pass/drop determination for packets, comprising the steps of (a) noting header combinations and values, and egress port destination for incoming packets; (b) comparing the header combinations and values with rule sets associated with the header combinations and values including egress port identities, and (c) returning a determination of pass or drop for the packet.
