<P><FONT SIZE=2 FACE="Arial">Hello,</FONT>
<BR><FONT SIZE=2 FACE="Arial">I have written a very simple H.248/SCTP Media Gateway application for loading up our Gateway Controller. Initially I had a lot of problems getting SCTP working, and finally it did with Debian Linux and Erlang OTP R11B-5. It works fine simulating one MGW, accepting over a 1000 calls/second, but I need to simulate multiple MGWs (to show calls between MGWs, and I have enough processor capacity & bandwidth to do it).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">There is only 1 network card available for SCTP, and I have multiple virtual interfaces. The problem is when I open another association and try to send data I get error "epipe". It does not matter if I open another erlang node, or try it on the same node. The IP addresses work individually, i.e. it's not the address that has the problem.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I would appreciate any help/comments on this,</FONT>
<BR><FONT SIZE=2 FACE="Arial">Best Regards,<BR>
Ken.</FONT>
