<p>A method for provisioning a transport service in a multidomain multi-layer network comprising at least one client layer network domains and at least one server layer network domain, said method comprising the steps of providing a virtual topology of each od said server layer network domain depending on connectivity requirements set by each of the served client layer network domains for a connectivity across said server layer network domains as at least one segment of said client layer network domain topology; determining an end-to-end path between two client nodes across one or more said server layer network domains based on an overlay topology comprising the virtual topologies provided by each of said server layer network domains, access links connecting client network nodes of said client layer network domains to said server layer network domains and inter-domain links interconnecting said server layer network domains in the client layer; and provisioning a transport service via the determined end-to-end path.</p> |
