摘要： In particular embodiments, a network element filters information sent to a neighboring network element. In the embodiments, the core network element may determine whether the neighboring network element is an edge network element or a core network element. If the neighboring network element is an edge network element, the core network element may set a filter, remove traffic engineering information according to the filter, and send the remaining information to the neighboring network element.

摘要： According to one embodiment, regeneration information indicating the optical reachability of a set of regeneration nodes is managed. Candidate paths from a source node to a destination node are calculated according to the regeneration information. The destination node is optically reachable from the source node along a candidate path. At least one candidate path is selected from the candidate paths.

In some embodiments, to determine the second path includes determining which ingress nodes are available in a domain that includes the destination node, where the available ingress nodes are not part of the first path, and implementing a disjoint path algorithm for each of the available ingress nodes. To determine the first path includes implementing forward path calculations.
