The scalability of routing and resource advertisement protocols is a key issue in large optical networks. A commonly used solution is based on the hierarchical approach adopted in IP/MPLS-TE networks, i.e., multiple areas or autonomous systems are pre-established to contain the geographical scope of the resource advertisement protocols and the related routing information. With arbitrarily pre-established areas, routing decision might be sub-optimal. Thus, special care must be paid by the… CONTINUE READING
