@norman, I will do it with in few days :), I would like to add OioSctp Transport and currently I am kind of stuck with following issue in io.netty.channel.socket.oio.OioEventLoop,

The problem is, I have a OioSctpEchoServer running and I can connect and send messages from a Nio/Oio Sctp Client, but when I stop the client and start again, connection is established and closed immediately with following exception

the reason for above issue is OioEventLoop thread is interrupted while it was blocking on sun.nio.ch.SctpChannelImpl.receive().

I have noticed that, OioEventLoop wakeup() method is directly interrupting the thread which is not like other EventLoop. So I tried after modifying wakeup method, problem was solved.

protected void wakeup(boolean inEventLoop) {
    interruptThread();
}  


@Override
protected void wakeup(boolean inEventLoop) {
    if (!inEventLoop && isShutdown()) {
        interruptThread();
    }
}

this happens because current OioEventLoop is not compatible with blocking SctpChannel? or am I missing something here?

Uh oh!

Port the SCTP transport #560
