11. A label switching router comprising:
a nonvolatile memory storing instructions; a working memory; and
a processor coupled to the nonvolatile memory and the working memory and configured to access the nonvolatile memory to retrieve the instructions and, in response, instantiate into the working memory an instance of a network service application, the network service application configured to:
upon determining that a bit error rate, a dropped frame rate, or a frame error rate of a link coupling the label switching router to a transit node has increased above a threshold:
decrease a reported available bandwidth of the link, the reported available bandwidth being a value that is reported and is independent of an actual available bandwidth of the link; and
generate a message into a switching network, the message comprising the reported available bandwidth;
maintain an internal meter associated with the bit error rate, the dropped frame rate, or the frame error rate of the link coupling the label switching router to the transit node; and
bias the internal meter.
