Is it correct that you think my problem can be addressed either by the followings?(1) Make the application timeouts longer. (Steve has shown that making an application timeouts twice the failover detection timeout would be a solution.)
Right. Is there something wrong with this approach?
(2) Let TCP have a notification of some kind.
There was some work on this in the IETF a while back (google trigtran linkup), but it never went anywhere to my knowledge. In principle it's possible, but it's not clear that it's worth doing. It's really just an optimization anyway. Imaging the link that's failing over is one hop or more away from the endpoint. You're back to the same problem again.
