METHOD FOR INTERCONNECTING LOCAL AREA NETWORKS OR NETWORK SEGMENTS AND A LOCAL AREA NETWORK BRIDGE

摘要

The invention relates to a method for interconnecting local area networks or network segments by means of a bridge (30). In the method, a local area network frame is received at the bridge (30) and forwarded across the bridge if its destination address refers to a network or network segment on the other side of the bridge. In order that a bridge simple in structure could be utilized in cases where priority is to be assigned to terminal traffic over datafile transfer traffic, the length of the frame to be forwarded is determined (31) with a predetermined accuracy, and the obtained length classification is utilized in the transmission of the frames for assigning priority to at least some of the shorter frames over the longer frames.
