Abstract
An ATM switch having a packet level discard function includes an upstream congestion detection circuit for detecting a congestion state of an ATM switch provided in the upstream and a packet level discard control table for holding at every connection a packet level discard priority indicating whether the ATM switch provided in the upstream has the packet level discard function or not, and wherein cells transmitted via an ATM switch not having a packet level discard function or an ATM switch which is not in the congestion state are packet-level-discarded with a priority to other cells. Thus, it is possible to improve a goodput of the ATM network in which ATM switches having a packet level discard function and ATM switches not having a packet level discard function are provided in a mixed state.
