<P>PROBLEM TO BE SOLVED: To provide a technique for efficiently suppressing failure occurrence associated with queuing buffer congestion in a frame transfer device with a plurality of queuing buffers. <P>SOLUTION: A frame transfer device comprises: three or more queuing buffers; a storage unit which stores a priority for reading frames from each queuing buffer; a buffer reading unit which reads and transfers a frame according to the priority; and a buffer writing unit which writes a received frame in any of the plurality of queuing buffers according to the information included in the frame. If it detects a congestion state of any of the first queuing buffers, the buffer writing unit replaces the priority of the first queuing buffer with the priority of a second queuing buffer (queuing buffer having a priority one higher than the first queuing buffer) when a prescribed condition is met. <P>COPYRIGHT: (C)2013,JPO&INPIT |
