<p>PROBLEM TO BE SOLVED: To provide a buffer unit and a switching unit that can avoid frame- interleaving and reduce that amount of hardware units. SOLUTION: The buffer unit and the switching unit are provided with fixed length packet storage means 28-1 to 28-m, that store a fixed length packet to each output path; a multi-cast processing means 29 that stores a multi-cast packet having destinations and that transfers the multi-cast packets to the fixed length packet storage means 28-1 to 28-m depending on the destination; and a control means 25 that monitors the storage state of the fixed length packet storage means 28-1 to 28-m and, that controls to transfer the multi-cast packets in-between variable length packets consisting of the fixed length packets, so that the task above is resolved.</p> |
