Abstract :
An interdomain routing protocol based on superdomains that always finds a valid path if one exists is presented. Both strong and weak constraints are maintained for each visible superdomain. If the strong constraints of superdomains on a path are satisfied, then the path is valid. If the weak constraints of a superdomain are satisfied but the strong constraints are not, the source uses a query protocol to obtain a more detailed “internal” view of the superdomain, and searches again for a valid path. The protocol handles topology changes, including node/link failures that partition superdomains
