Abstract

A switching node (11(n)) for use in connection with a computer network (10) includes an input interface (30), a buffer (32) and a control element (35). The input interface (30) receives cells from at least one input communication link. The buffer (32) buffers selected cells prior to transmission over at least one output communication link. The control element (35) selectively enables cells received by the input interface (30) to be buffered in the buffer (32) and discards cells if the cell occupancy of the buffer (32) exceeds a predetermined threshold level and receiving a credits value indicating that the switching node (11(n)) has loaded a number of cells into the buffer (32) exceeds a cell loss ratio guarantee provided by the switching node (11(n)).
