In Nortel implementation the path can switch back if there are better
resources.

My understanding is that ATM's PNNI is not a best path routing protocol
in the same sense as RIP or OSPF. So long as the nodes can maintain
established QoS for a VC the switching path will go unchanged. Compare
with MPLS which would make your topology switch back to a shorter path
upon recovery of the direct link.
