随着网络技术的不断发展,许多新的网络应用需要端到端的服务质量保证。为了解决端到端的服务质量保证和系统公平性等问题,该文提出了一种基于比例区分服务的网络比例公平调度策略——nPFS策略。该调度策略综合考虑了网络效率、用户服务质量要求和系统公平性等多个性能目标,使用比例公平性原则,有效地实现了多性能目标的端到端传输控制,同时保证系统的公平性。实验结果表明:该文提出的网络比例公平调度策略,可以有效保证多服务类间的比例公平,特别是端到端的服务质量比例公平性。
With the continuous development of network technology, many new network applications require end-to-end quality of service assurance. In order to solve the problem of end-to-end quality of service assurance and system fairness, this paper proposes a proportional proportional dispatch-based network proportional fair scheduling strategy - nPFS. This scheduling strategy comprehensively considers several performance objectives such as network efficiency, user service quality requirements and system fairness. Using the principle of proportionality and fairness, the scheduling strategy effectively implements the end-to-end transmission control of multi-performance targets while ensuring the fairness of the system. The experimental results show that the proposed network proportional fair scheduling strategy can effectively ensure the proportion of multi-service class fair, especially the proportion of end-to-end quality of service fairness.
