<p><P>PROBLEM TO BE SOLVED: To materialize a method for restoring cells arriving in random sequence from asynchronously operating exchange parts, by a small amount of hardware. <P>SOLUTION: A plurality of exchange parts asynchronously exchange data. Distributing parts as inputs of a switch fabric manage serial numbers continuous for each destination. Each distributing part divides an input variable length packet into fixed length cells, adds serial numbers corresponding to one or more destinations to one or more cells, and outputs the cells to the exchange parts. Each exchange part delivers the cells to the objected destinations. Each of alignment parts as outputs of the switch fabric classifies received cells by numbers of the distributing parts, and compare an expected value of serial numbers managed by the alignment part with serial numbers of destinations (alignment parts) which the received cells have. Received cells of which the serial numbers coincide with the expected value are stored in an aligned FIFO queue to take out cells from a packet start cell to a packet end cell. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
