Hi!

We are doing a project measuring handover times on different technologies
including mSCTP. During our work we have noticed a problem regarding
transmitting SACKs on the interface which communication is handed over to.

This is how we do: We have a stream server continuously transmitting data to a
client running the terminal program, which is included in the sctplib. When we
want to perform the handover, we use the SETPRIM command, which transmits an
ASCONF to the server updating its primary path. This works perfectly, however
the SACKs from the server are still transmitted on the “old” interface.

One workaround is to modify the routing table, but we don’t like this solution,
so we hope that someone out there can help :)
