摘要： The present disclosure provides distributed domain network planning systems and methods. The network planning systems and methods include a distributed domain network planning system that adapts planning concepts to networks operated by modern distributed control planes, such as ASON/ASTN, GMPLS, etc. The network planning systems and methods operate on a multi-domain network utilizing a control plane and local planning systems associated with each individual domain in the multi-domain network. The network planning systems and methods also operate on a single domain network utilizing a control plane and local planning systems associated with the single domain network. The network planning systems and methods build on a distributed control plane philosophy that the network is the database of record. There is significant operational value to distributing the planning function of a large network using the systems and methods disclosed herein.

摘要： A method and system of determining a new path through an optical network from a source node to a destination node when a link in an original path fails are disclosed. When a fault on a link is detected, adjoint weights are assigned to each operational link for each node on the original path. A connection cost is determined for each node based on the adjoint weights of the links connected to the node. A new path through the optical network is determined based at least in part on the adjoint weights and the connection costs.
