Hi,
I have a general question about lksctp's fast retransmit implementation.
I am currently using lksctp-tools-1.0.6-1.i386.rpm on my server side.
After setting up an sctp connection, I am seeing proper messaging while
we run various messages over the SCTP stream. The issue that I am seeing
is when a packet is lost in the network. Presently, when a TSN is lost
on our client side, it starts transmitting sack messages with gap
reports. The server side is receiving the gap sack messages, however it
is not retransmitting the packet until the rto timer expires. Since the
rto timer increases, eventually the whole sctp association is going down
when too many gap reports are received without a retransmission.
I am curious why we are not seeing fast retransmit after 4 gap reports
are received. Is there some setting that will affect fast retransmit
being on or off?
Thanks,
Brandon Moreno
