  • Path management for enhanced protection
    Patent number: 7961603
    Abstract: Methods and node capable of establishing link-weights based on protection-factor linked to protection level of a plurality of links between a source node and a destination node and capable of establishing primary and, potentially, protection path proposals using the established link-weights. An available bandwidth value for the link is determined. If the available bandwidth value for the link is greater than the bandwidth requirement associated to the potential path, then the link-weight of the link is set by computing a protection-factor associated to the link with the available bandwidth value for the link. Otherwise, the link-weight of the link is established to a value that indicates that the link should not be part of the potential path. Shortest path algorithm using the established link-weights could be applied to obtain path proposals.
