Each cell is, for example, an ATM cell including a channel label that uniquely identifies, for the input port on which the cell is received by the apparatus, a virtual channel with which the cell is associated. In order to provide the master VCN of each cell received, a K-dimensional lookup table storing master VCNs is created. Then for each cell received, a long channel identifier is generated by combining the channel label of the cell with a port label identifying the input port on which the cell was received. Preferably, the long channel identifier is scrambled before being split to provide K keys. Next, these keys are converted into shorter indexes using, for example, simple lookup lists. Finally, the indexes are used to access into the table storing the master VCNs in order to retrieve the master VCN for the cell concerned. The same approach may also be used to provide master VCNs for systems using variable-length packets.Other References
