<p>A packet switching system capable of ensuring the sequence and continuity of packets and further compensating for delays in transmission is disclosed. Each of two redundant switch sections (31, 32) has a high-priority queue (8) and a low-priority queue (9) for each of output ports. A high-priority output selector (23) selects one of two high-priority queues corresponding to respective ones of the two switch sections to store an output of the selected one into a high-priority output queue (25). A low-priority output selector (24) selects one of two low-priority queues corresponding to respective ones of the Lwo switch sections to store an output of the selected one into a low-priority output queue (26). The high-priority and low-priority output selectors are controlled by a switch controller (6) depending on a system switching signal and a packet storing status of each of the high-priority and low-priority queues. <IMAGE></p> |
