based on a previous discussion we observed that we can have network failures
which are either on the local link or somewhere along the path between a
source and a destination. observing the local link only addresses only some
problems - not all. a number of other working groups have made similar
observations.

we also agreed that mobike depends on information from a number of other
protocols (including link layer protocols). these protocols provide hints to
mobike. 

you are right: mobike is certainly not a link layer protocol. no
disagreement about it.
