Abstract: Multi-domain traffic engineering is a major focus area for carriers and crankback signaling offers a very promising alternative. However, even though various crankback studies have been done, there remains significant latitude for improved multi-domain designs. To address these challenges, this work develops a novel solution for intra/inter-domain signaling crankback in IP/MPLS networks. Namely, dynamic intra-domain link-state routing information is coupled with inter-domain path/distance-vector routing state to improve the search process. Mech...
