nPFS: efficient management of multiple QoS objects

Current proposals for the packet scheduling strategy of multiple performance objects in high-speed packet-switched networks attract more and more attention. At the same time, the end-to-end Quality of Service (QoS) requirements need to be satisfied and the network resource should be allocated fair and efficiently. In this paper, we provides nPFS, a network proportional fairness scheduling strategy in packet-switched networks from proportional fairness principle, and the nPFS integrates several objects, such as the network performance, user's QoS requirement and system fairness. Then it is analyzed and proved in detail. Moreover, the nPFS can be applied to design and improve the scheduling strategy and algorithms in packet-switched networks.
