| 20100091784 | FILTERING OF REDUNDANT FRAMES IN A NETWORK NODE - A method of filtering redundant frames including a MAC source address, a frame ID and a CRC value, in a network node with two ports each including a transmitting device and a receiving device, is provided. The transmitting device includes a transmission list in which frames to be transmitted are stored. The receiving device includes a receiving memory for storing a received frame. For filtering redundant frames in a network node, a first frame is received by one of the two ports. After reception of the MAC source address and the frame ID of the first frame in the transmission list of the port, a second frame with the same MAC source address and frame ID is sought. If the second frame is present, the first frame is neither forwarded to a local application nor forwarded to send to other ports, and the second frame is not sent. | 04-15-2010 |
