<p>Disclosed are a communication packet processing apparatus and method for a ring topology Ethernet network capable of preventing permanent packet looping which can maintain the performance of the network by preventing generation of the permanent looping in the ring topology Ethernet network. The communication packet processing apparatus and method compare a destination MAC address of a communication packet with a MAC address of a communication node, decide whether to transfer the communication packet to a CPU according to the comparison result, compare a source MAC address of the communication packet with the MAC address of the communication node, and decide whether to terminate the communication packet or transfer the communication packet to another communication node according to the comparison result.</p> |
