Subject: [tcp-dsack] interface for retrieving dsack information
Date: Tue, 14 Jul 2009 20:21:58 -0400	[thread overview]
Message-ID: <46bf9ede0907141721g5b7763b2hf2b6ec1c7a5782a6@mail.gmail.com> (raw)

Hi,

I'm trying to count the number of unnecessary retransmissions for a
tcp connection. DSACK reports the receipt of duplicate segment to
sender, so I plan to count the duplicate transmissions reported by
DSACK as unnecessary retransmissions. My question is if there is a
nice interface, like tcp_info, which can be used for retrieving the
number of duplicate transmissions from DSACK? tcp_info structure
doesn't include such information.

Thanks a lot.

Yinglin
