A method and apparatus colors the conventional error codes of each word of a multiword transmission to facilitate the detection of words which are out of order or not part of the transmission, without affecting the data in the word. A 1-bit by n-bit matrix is assembled using the header word, and zeros for the header of the multiword transmission, or the data word, error code, if any, an identifier portion of the header word and zeros for each data word, and the 1-bit by n-bit matrix is multiplied by an n-bit by m-bit matrix assembled from a conventional error coding matrix and other matrices. The result either produces an error code to be sent with the header or data, or a check code to be verified as all zeros to indicate the absence of bit errors within the header or data word, and that the word is in the proper packet and in the proper sequence within the packet. An alternate method and apparatus colors the data portion of certain words of multiword transmissions to provide an alternate manner of facilitating the detection of words which are out of order or not part of the transmission.

In a relay device, a first memory stores correspondence information representing a correspondence relationship between a node and a port. A second memory stores information by which a port to suppress flooding of a frame is distinguishable. A relay part limits a port, which floods a frame addressed to a node of which information is not stored in the first memory, based on the information stored in the second memory.
