Abstract: Multi-domain traffic engineering is a very challenging problem area and crankback signaling offers a very promising solutions framework herein. Although some initial crankback studies have been done, there is still significant latitude for improving multi-domain crankback performance. Along these lines, this paper studies realistic IP/MPLS multi-domain networks and proposes a novel solution for joint intra/inter-domain signaling crankback. Namely, dynamic intra-domain link-state routing information is coupled with available inter-domain path/di...
