First Claim
Patent Images
1. A method of transmitting an Ethernet frame via a network bridge, the method comprising:
- receiving a frame header from a previous node connected to the network bridge;
receiving a header cyclic redundancy check (CRC) flag and header CRC with respect to the frame header from the previous node;
determining whether to forward the Ethernet frame including the frame header by referring to the header CRC flag and the header CRC; and
forwarding the Ethernet frame from the previous node to a next node connected to the network bridge according to the determination.

19. A network bridge apparatus transmitting an Ethernet frame, the network bridge comprising:
-
a frame receiving unit configured to receive the Ethernet frame from a previous node connected to the network bridge; a CRC unit configured to perform a CRC with respect to a header of the Ethernet frame by using a header CRC flag and a header CRC included in the Ethernet frame, or for performing the CRC with respect to an entire Ethernet frame by using a CRC field of the Ethernet frame; a state management unit configured to determine an operation state of the network bridge according to a result of the CRC; and a frame transmission unit configured to discard the received frame or configured to transmit the received frame to a next node by referring to the operation state and the result of the CRC. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
