Technical Summary

	This document replaces RFC 1323, making minor fixes and
	clarifications to the original document. The document
	specifies three performance enhancing extensions to TCP, using
	two TCP options. The first is window scale option, that allows
	representation of receive window sizes larger than 2^16 bytes
	originally allowed by the 16-bit window field. The second
	option is TCP timestamps option that allows round-trip time
	measurement on each TCP segment, and third is an algorithm to
	detect and reject old duplicate segments that happen to match
	the current TCP window (Protect Against Wrapped Sequence

Working Group Summary

	This document has been a chartered TCPM working group item
	since year 2008. It has not been under significant
	controversy, but the progress has been slow because of earlier
	lack of WG (and authoring) cycles. Since adding a new
	co-editor, the progress on the draft became faster in the
	working group.

Document Quality

	The predecessor of this document, RFC 1323, was published in
	1992, and is deployed in most TCP implementations. This
	document includes fixes and clarifications based on the gained
	deployment experience. The recent versions of the document
	have been reviewed and discussed by multiple working group
