Abstract
Under an environment where a packet retransmission is performed, a packet receiving device includes a reordering section, configured to perform a reordering of a receiving packet in a lower layer than a network protocol stack, and a buffer section. Out-of-Order packet among receiving packets is associated with a flow and stored in the buffer section. The reordering section determines whether the receiving packet is an In-Order packet or an Out-of-Order packet. In a case where the receiving packet is an In-Order packet of a flow and an Out-of-Order packet of the flow is stored in the buffer section, the reordering section transfers the receiving packet to the network protocol stack and then transfers all of Out-of-Order packet of the flow stored in the buffer section to the network protocol stack.
