  • Method of filtering packets in network switch and related filter
    Patent number: 11991080
    Abstract: A method for packet filtering in a network switch includes: utilizing an access control list circuit to filter received packets, wherein the access control list circuit compares header information of the received packets with an access control list to filter the received packets, where the access control list has at least one entry, and rule information in the entry includes only a portion of an IP address; and utilizing a routing circuit to further filter packets that pass the access control list circuit, wherein the routing circuit compares header information of the packets that pass the access control list circuit with a routing table to filter the packets, wherein the routing table has at least one entry, and rule information in the entry includes an entire IP address.
