Abstract
A system (,) is provided for identifying a processing port (,) and a link (,) at which a cell (,) is received. The system (,) includes a logical link table (,) having a plurality of logical link entries (,). Each logical link entry (,), which corresponds to a particular link (,) of a processing port (,) associated with the logical link table (,), specifies a numerical value. The processing port (,) may receive the cell (,) at one of a plurality of links (,). The processing port (,) can convert the cell (,) by replacing a numerical value of an identification field, such as a virtual channel identification field (,), of the cell (,) with the numerical value specified by the logical link entry (,) corresponding to the link (,) at which the cell (,) is received. A switch control module (,), which is connected to the processing port (,), may receive the converted cell (,). The switch control module (,) can identify the link (,) and the processing port (,) at which the cell (,) corresponding to the converted cell (,) was received by referencing a reverse mapping table (,) using the numerical value of the logical link entry (,) in the converted cell (,).
