Hi

RFC 4653:
I am looking for an Implementation of RFC 4653(Improving Robustness of TCP
for Non Congestion Events) in FreeBSD and I figured from the to-do page
http://wiki.freebsd.org/Networking that it is yet to be implemented.
Is that true still?(as the page seems to have been updated an year ago).

RFC 3517 : Again, Is this implemented as per the RFC or FreeBSD has its own
version of SACK based Loss recovery for TCP? Reason that this question is
raised being that the to-do list for FreeBSD/Networking  says "Review
FreeBSD TCP SACK implementation against RFC 3517's Conservative SACK
Recovery Scheme"

Expecting your inputs,
S Lakshmi Narasimhan
