Hi,

I would like to get the values of SCTP congestion control algorithm
variables  (*cwnd, ssthresh, flightsize *and* pba)* from any SCTP based
application in runtime for research purpose. Does any API exist in SCTP for
that?  Do I need to dig the SCTP code in kernel to get the values?

I will appreciate any help in this regard.
