Congestion managed traffic engineering services in multiprotocol label switching and generalized multiprotocol label switching networks

An apparatus configured to mitigate congestion in a multi protocol label switching (MPLS) network, comprising:

• means for monitoring, at a network element, a traffic drop count due to traffic queue overflow on at least one of a traffic queue coupled to a link and a network interface coupled to the link;
• means for converting the traffic drop count to a normalized congestion indicator for the at least one of the traffic queue and the network interface;
• and
• means for optimizing, based on the normalized congestion indicator, a route of a label switched path in the MPLS network so the route avoids the link.

A non-transitory computer-readable medium, comprising:

• instructions stored thereon that, if executed by a processor, cause the processor to:
• monitor, at a network element, a traffic drop count due to traffic queue overflow on at least one of a traffic queue coupled to a link and a network interface coupled to the link;
• convert the traffic drop count to a normalized congestion indicator for the at least one of the traffic queue and the network interface;
• and
• optimize, based on the normalized congestion indicator, a route of a label switched path in the MPLS network so the route avoids the link.
