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
