Proportional Differentiated Services for End-to-End Traffic Control

摘要

Due to multiple performance objectives of network traffic control, corresponding packet scheduling strategy in next generation broadband service convergence network 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.
