Abstract:
Processing an ingress packet in a packet pipeline to determine a forwarding rule includes identifying a matching rule in each forwarding table in the pipeline. Prefix lengths of the respective matching rules are compared. The matching rule with the greatest prefix length serves as the basis for forwarding an egress packet.
