AUTOMATED TRAFFIC ENGINEERING BASED UPON THE USE OF BANDWIDTH AND UNEQUAL COST PATH UTILIZATION

摘要

A method in a network element improves load distribution in a network that includes the network element. The network element is one of a plurality of network elements in the network each of which implement a common algorithm tie-breaking process as part of a computation used to produce minimum cost shortest path trees. The network element includes a database to store the topology of the network. A set of service attachment points is mapped to network elements in the topology for services individually associated with an equal cost tree (ECT) set and associated with per service bandwidth requirements. The topology of the network includes a plurality of network elements and links between the network elements. The method generates multiple ECT tree sets for connectivity establishment and maintenance of the connectivity in the network. The method defines a bandwidth aware path selection. The method reduces the coefficient of variation of link load across the entire network.
