Method, system and article for improved TCP performance during retransmission in response to selective acknowledgement

摘要

A TCP/IP retransmission frame contains multiple TCP segments containing non-contiguous missing packets from a data communication. A TCP option in the first segment in the frame indicates the presence of multiple TCP payloads in the frame. Each TCP payload has a corresponding prepended TCP header. An offset address specified in each TCP header within the frame identifies the location of the next TCP header in the frame. Network throughput performance is enhanced by permitting multiple non-contiguous packets to be retransmitted in a single IP packet.
