TCP packet delivery failure

In the case of packet being successfully delivered, MINA does fire IoHandler.messageWritten(). But if from some reason, the packet can not be delivered, is there a notification that my application can listen to to process failure workflow?

Thanks,
Akbar.

Unfortunately, no.  It's an O/S that guarantees the delivery.
messageWritten event is fired when the data is written out to the kernel
write buffer.  To make sure the message is delivered, you will have to wait
for an acknowledge message from the remote peer by redesigning/refactoring
your protocol.

HTH,
