It has been observed that transient failures are fairly common in IP
backbone networks and there have been several proposals based on local
rerouting to provide high network availability despite transient
failures.  Previously, we proposed failure inferencing based fast
rerouting for IP backbone networks that protects against single
failures, but can cause forwarding loops in case of multiple
simultaneous failures.  On the other hand, blacklist-aided forwarding,
we proposed earlier for wireless mesh networks, provides loop-free
forwarding even in the presence of multiple failures in the network
but requires that each packet carry a blacklist of failed links
encountered along its path. Our aim is to achieve the best of both
these approaches, i.e., successfully deliver packets while ensuring
loop-freedom even in case of multiple failures without changing packet
format significantly.  We propose blacklist-based interface-specific
forwarding (BISF) that infers a blacklist, a list of links that might
have failed, based on a packet's incoming interface and its
destination, and determines the next-hop by excluding the blacklisted
links.  We present three variants of BISF that differ in their
delivery guarantees and in the number of additional bits needed. BISF0
requires no changes to the packet format but offers no delivery
guarantees, whereas with one more bit BISF1 assures delivery under
single link failures while BISFn needs more than one additional bit
but ensures delivery under single node failures also. We show that all
variants of BISF provide fast loop-free local rerouting regardless of
the number of failures in the network while forwarding packets
successfully in most cases.
