Abstract:
A short cell multiplexing apparatus comprising:a first header converting section; a short cell multiplexing section; and a second header converting section, wherein said first header converting section output's, when a plurality of partial fill cells which are standard cells each storing one short cell are inputted in the first header converting section, the partial fill cells, while converting a value of a virtual path identifier stored in each of the partial fill cells into a value that is a unit of a multiplexing process at said short cell multiplexing section, and converting a value of a virtual connection identifier stored in each of the partial fill cells into a value to be a short cell connection identifier which is to be stored in the short cell at said short cell multiplexing section; wherein said short cell multiplexing section receives a plurality of the partial fill cells outputted from said first header converting section to multiplex a plurality of the short cells stored in the partial fill cells for every virtual path identifier which is stored in each of the partial fill cells, produces a cell in which virtual channel identifiers of the partial fill cells are stored as the connection identifiers of the short cells, and the virtual path identifiers of the partial fill cells storing the short cells are stored as the virtual channel identifiers, and outputs the cell; and wherein said second header converting section receives the cell outputted from said short cell multiplexing section, and outputs the cell while converting the respective virtual path identifiers and virtual channel identifiers which are stored in the cell into given values.
