Abstract
A network node, such as an Ethernet switch, is configured to monitor packet traffic using regular expressions corresponding to Access Control List (ACL) rules. In one embodiment, the regular expressions are expressed in the form of a state machine. In one embodiment, as packets are passed through the network node, an access control module accesses the packets and traverses the state machine according to certain qualification content of the packets in order to determine if respective packets should be permitted to pass through the network switch.
