This mechanism is used in a high performance network composed of traditionnal network access nodes connected through one or several frame switching nodes (FSNs) which realize the network transit function. The main characteristics of the FSN are: . Multiplexing of HDLC (high level data link control) frames of variable length. . Routing of the incoming HDLC frame to the selected output line according to the routing tag information included in the transmission header of each frame. No error recovery. . Frame drop in case of overflow. The problem is to design a routing tag which can be easily calculated by the network access node, and decoded by the frame switching node.
