Abstract
A cell relay switch includes an output port for transmitting cells to multiple destinations. The output port further includes a queuing buffer, a controller, and an output processor. The buffer receives a plurality of cells of a packet from a source. The buffer temporarily stores the cells before transmission by the output processor. The controller controls the storing of the received cells in the buffer by determining a total number of the cells in the packet and a number of cells to be received from different packets, deciding whether the buffer contains sufficient space to store the received cells based on the total number of cells in the packet, the number of cells to be received from the different packets, and the rates at which cells are received and drained from the buffer. The buffer is commanded by the controller to store the received cells when the buffer contains sufficient space and discard the received cells when the buffer contains insufficient space.
