I guess that the only one that can identify this problem is the ULP itself.

So i guess we have the following situation:
- The shim will only be able to detect (by itself, without additional information) failures when packets stop flowing

How do you know if packets should or should not be flowing? What if it's a very quiet protocol? :)


well, imho the shim needs only to define a default failure mode. I mean, it is clear that different apps have different perception of what a failure may be, but, since the shim is a generic layer, we need to provide a generic definition of what a failure is. Clearly, i guess it would be very useful to allow ULPs to provide information to the shim about when they consider that a failure has occurred.

Or define a very simple link^Wpath-state control protocol for shim6.

You could use it to monitor path-state to locators you're interested in.
