Traffic Engineering QoS-Driven Disjoint Path Routing Model Research

This paper investigates the Traffic Engineering QoS-driven disjoint path routing optimization model in communication networks. The Traffic Engineering multipath routing mathematical model was modified to optimize load balancing and prioritize packet flows according to their Quality of Service requirements. We applied a linear optimality criterion to minimize link utilization and balance the load of network links. We also improved the conditions for the balanced loading of network links by considering the flows priorities. The work validated the effectiveness and feasibility of the proposed solution through numerical examples. It showed that the model applied can provide differentiated QoS under disjoint routing with load balancing.
