Future optical backbone networks will be able to dynamically reconfigure optical connections in a few minutes and migrate the routes of existing connections with little service interruption at the IP layer, using the optical bridge-and-roll technique. A high data-rate dynamic wavelength service for these networks will provide more flexible connection services to customers. A customer owns or leases a few terminal ports in the network and is able to configure their connections freely between pairs of spare ports on demand. The carrier must provision enough resources in advance to accept any valid customer connection request.
