Abstract:
1. A method, implemented by operation of a computer, comprising: receiving an outbound or an inbound packet in one of a plurality of network nodes; determining whether an outbound queue in said one node is full and, if so, further determining whether any packets stored in said outbound queue may be discarded and, if so, discarding one of said any packets; discarding said outbound packet if none of said any packets may be discarded; incrementing a sequence number for said outbound packet and storing said outbound packet with said sequence number in said outbound queue when said outbound queue is not full or when said one of said any packets is discarded; and determining whether said outbound packet requires high-reliability delivery and, if so, sending said outbound packet from said outbound queue to a low bandwidth link outbound queue within said node.
