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
numbers).
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
participants.
