Multiple Metric QoS Routing in Differentiated Services Networks Using Preference Functions Measurement Concepts

摘要

QoS routing protocols involving several combinations of network metrics can be difficult to solve in polynomial time. Our research introduces a novel approach that allows bandwidth brokers to perform QoS management in Diffserv Domains with any number and combina-tion of network metrics with algorithm complexity of O(m(n + 1)) where m is the number of paths between two edge devices in the network and n is the number of metrics involved.
