| 1. A system for configuring constraint based routing in multi protocol label switching traffic engineering with a policy based
management approach across a network, comprising:
network interfaces configured to have link attribute definitions set;
a memory configured to store affinity profiles configured to identify at least one link attribute as preferred or not preferred;
a policy server configured to attach the affinity profiles to a multi-protocol label switching tunnel such that the affinity
profiles and the link attribute definitions are shared across a network to construct service and network policies; and
a link attribute definition object that is configured to define the semantics of the link attributes and the affinity profiles,
wherein the link attribute definition object is further configured to describe a policy target by defining a representation
for each attribute bit and for each affinity bit in the affinity profile.
