Abstract
A communications network component comprising a processor configured to implement a method comprising sending a fault message including degradation data, wherein the degradation data indicates a bandwidth reduction associated with a partial fault is disclosed. Also disclosed is a method comprising receiving a fault message comprising degradation data associated with a fault, determining whether an available bandwidth is less than a bandwidth reserved for a plurality of connections associated with the fault, and modifying the bandwidth reserved for the connections if the available bandwidth is less than the bandwidth reserved for the connection.
