ABSTRACT:
A strip frame recognition apparatus which is installed in a station of a token ring local area network for recognizing a received frame as a strip frame which has been transmitted from the station in order to prevent the frame from going around a ring more than one round, comprising a transmission frame strip address extraction circuit (101) for extracting a strip address from a predetermined field of a transmission frame, a retention circuit (12) for retaining the strip address extracted by the extraction circuit (101), a received frame strip address extraction circuit (111) for extracting information corresponding to the strip address from a received frame, and a coincidence detection circuit (13) for comparing the information extracted by the extraction circuit (111) with the strip address retained in the retention circuit (12), detecting coincidence beween the information and the strip address, and judging by detection of the coincidence that the received frame is the strip frame.
