In-vehicle communication device that processes packets based on acl (access control list) and udf (user defined field)

Abstract

An in-vehicle communication device that processes packets based on an Access Control List (ACL) and a User Defined Field (UDF), includes a CPU subsystem configured with a plurality of high-performance cores that are electrically isolated from each other, a communication interface including a plurality of Ethernet communication ports, and an Ethernet Packet Processing Engine (EPP) that performs a routing function between the plurality of Ethernet communication ports. The Ethernet Packet Processing Engine (EPP) performs at least one of security inspection, filtering, forwarding, VLAN tagging, and mirroring of an input packet based on a plurality of ACL entry tables and a plurality of UDF entry tables.

Dependencies are inferred from the claim text.
