Out of order packet buffer selection

A method for storing a packet in an application buffer of a processor node, the method comprising:

• receiving, at a first network interface controller of the processor node, a first out of order (OOO) packet within a stream of packets transmitted from a second network interface controller in a sequence represented by respective sequence numbers that are assigned to corresponding packets in the stream, the first OOO packet being received out of order relative to at least a first missing packet of the stream of packets;
• selecting, at the first network interface controller, one buffer from among multiple buffers for storing the first OOO packet, the multiple buffers including an OOO buffer associated with the first network interface controller and the application buffer associated with the first network interface controller, wherein the OOO buffer is configured to store OOO packets, and wherein the first network interface controller is configured to store the stream of packets in sequential order in the application buffer;
• in response to the first network interface controller selecting the application buffer for storing the first OOO packet, storing the first OOO packet in the application buffer;
• and
• in response to the first network interface controller selecting the OOO buffer for storing the first OOO packet:
• storing, by the first network interface controller, the first OOO packet in the OOO buffer, and
• after receiving the missing packet, copying the first OOO packet from the OOO buffer to the application buffer.
