ABSTRACT:
The present invention is an apparatus that manages Packet-Discard at a switch in an ATM network. The apparatus includes a table having a number of table addresses (or indexes). Each table address stores a record for incoming data cells of a frame. The records indicate whether data cells of the frame are be discarded. The number of possible cell identifiers is greater than the number of table addresses. The apparatus also includes a processor unit which receives a data cell having a cell identifier. The processor unit determines a table key, based on the cell identifier such that the table key is within the range of the table addresses. The processor unit then searches a record in the table associated with the table key to determine whether the data cell is to be discarded.
