Generating network link utilization targets using a packet-loss-versus-link utilization model

Abstract:

A method and system are described for automatically determining network utilization bounds in order to meet per-link packet loss rate targets through the network. A loss-verses-utilization model is continuously re-generated as part of a feedback loop to update link utilization targets. A target loss rate can be used to generate a link utilization target value using the model. The link utilization target value can be used in a variety of network update models, such as traffic engineering, capacity planning and risk management. Updates can be applied to individual network links, network devices as a whole, or groups of devices (based on type or position in the network).
