Abstract
Systems and methods for multi-domain routing are provided. In some embodiments, a method for determining a path calculation from a source node to a destination node over a multi-domain network is provided. The method may include steps for receiving a predetermined sequence of domains for communicating information from the source node to the destination node, determining a link type for each of a plurality of links in the predetermined sequence of domains, modifying the link type of one or more of the plurality of links such that the plurality of links are unidirectional links towards a destination node, and determining a path along the predetermined sequence of domains based on the modified plurality of links.
