Abstract:
1. A device, comprising: an input buffer configured to store a set of input entries for multicast packets to be transmitted via ones of a plurality of output ports of the device; a congestion buffer configured to store a set of congestion entries for multicast packets to be transmitted by the device via congestion affected ones of the plurality of output ports; and a plurality of output buffers including first, second, and third output buffers, wherein the first, second, and third output buffers are respectively configured to store a set of output entries for packets to be transmitted via first, second, and third ones of the plurality of output ports; wherein the input buffer is configured to store an input entry for a first multicast packet to be transmitted via at least the first, second, and third output ports; wherein the device is configured, in response to the first output port not being congestion affected but the second and third output ports being congestion affected, to cause: wherein the device is configured to modify the destination information in the congestion entry based, at least in part, on a subsequent indication that at least one of the second and third output ports is not currently congestion affected.
