PACKET EXCHANGE WITH CONTROL PART CONNECTED IN CASCADE AND SWITCHING MATRIX CONNECTED IN CASCADE WITHOUT BUFFER

摘要

PROBLEM TO BE SOLVED: To secure data exchange without colliding in packet form. SOLUTION: This invention relates to a packet exchange having a switching network for several cascade connected switching controls (7) assigned to each of several switching matrices having no buffer and a switching matrix (6). Each switching control (7) includes a discrimination information analyzer (12) that discriminates a input port in a route discrimination information assigned to a packet, an output assigner (13) that evaluates the route discrimination information, a composition unit (14) that stores assignment acceptable to each input and output port, and an assign and analyzing device (15) that changes the route discrimination information and guides to port controllers (2 to 5).
