Abstract
An orchestration layer includes one or more processing devices communicatively coupled to a plurality of domains in a multi-domain network, wherein the one or more processing devices are configured to receive a request for a path, wherein the path is requested from a source in a first domain to a destination in a second domain in a multi-domain network including a plurality of domains, relay the request to each domain in the multi-domain network, and wherein each domain in the multi-domain network is configured to compute a matrix fragment and the matrix fragments from a plurality of domains are used to find the path, and provide a response with the path from the source in the first domain to the destination in the second domain.
