General method for network providers to choose applications with guaranteed QoS



In the presence of the competition for network resources, network providers may experience some difficulty in providing throughput as specified by service-level agreements. Moreover, fulfilling a quality of service (QoS) agreement for a specific application may affect QoS agreements for other applications served by the same network provider. We describe a model to estimate QoS for single and multiple applications and offer a method for a network provider to choose a set of applications with a guaranteed QoS in order to maximize profit with respect to limited network resources. We describe and compare four suboptimal algorithms which can be used when optimal methods cannot be employed. © 2011 Alcatel-Lucent.
