[e2e] How prevalent is Timestamp option and PAWS?

[Anilkumar Vengalil (PLATIN/ph)]

Hi,

I wonder how prevalent is the use of PAWS (Protect Against Wrapped
Sequence Number) in modern TCP implementations ? As per RFC 1323 (section
4, page no. 17) any TCP using timestamp  can optionally implement this.
But, has it really been implemented in modern TCPs? Any statistics?

Also, any statistics on No. of hosts using timestamp option as specified
in RFC 1323

Thanks,
Anil
