Summary:A router (600) for a communication satellite includes a multiport shared memory (804) with storage for at least two downlink hop location queues, a packet switch (608) that routes self addressed uplink data from an input port to an output port coupled to the multiport shared memory (804), and a routing table (702) coupled to the packet switch (608). The routing table (702) stores queue tags (714) that identify at least one of the downlink hop location queues in which the uplink data should be stored. In addition, the routing table stores routing tags (712) the direct the packet switch (608) to route the uplink data from one of its input ports to one or more of its output ports.
