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.
This document is a product of the TCP Maintenance and Minor Extensions Working Group of the IETF.
This is now a Proposed Standard.
