-RFC 1323 Window Scaling & Timestamps
+{{public:rfc1323.pdf |RFC 1323 Window Scaling & Timestamps}}
+   This memo presents a set of TCP extensions to improve performance
+   over large bandwidth*delay product paths and to provide reliable
+   operation over very high-speed paths.  It defines new TCP options for
+   scaled windows and timestamps, which are designed to provide
+   compatible interworking with TCP’s that do not implement the
+   extensions.  The timestamps are used for two distinct mechanisms:
+   RTTM (Round Trip Time Measurement) and PAWS (Protect Against Wrapped
+   Sequences).  Selective acknowledgments are not included in this memo.
