A large-scale multiprocessor system with a link-level interconnect that provides in-order packet delivery. The method comprises transmitting, over a link in the defined interconnection topology, a sequence of packets in a defined order from a first node to a second node. The second node is an intermediate node in a route between the first and third node. At the first node, the transmitted packets are stored in a buffer. In response to an error in reception, the first node retrieves packets from the buffer and re-transmits them to the second node, beginning with the packet subsequent to the last packet in the sequence correctly received by the second node and continuing through the remainder of the sequence of packets.
