The TCP protocol [RFC0793] was designed to operate reliably over almost any transmission medium regardless of transmission rate, delay, corruption, duplication, or reordering of segments. Over the years, advances in networking technology have resulted in ever-higher transmission speeds, and the fastest paths are well beyond the domain for which TCP was originally engineered.

                   TCP Extensions for High Performance


   This document specifies a set of TCP extensions to improve    performance over paths with a large bandwidth * delay product and to    provide reliable operation over very high-speed paths.  It defines    the TCP Window Scale (WS) option and the TCP Timestamps (TS) option    and their semantics.  The Window Scale option is used to support    larger receive windows, while the Timestamps option can be used for    at least two distinct mechanisms, Protection Against Wrapped    Sequences (PAWS) and Round-Trip Time Measurement (RTTM), that are    also described herein.

   This document obsoletes RFC 1323 and describes changes from it.
