【摘要】 <正> 1.引言现在Internet主要提供无服务质量(QoS)保证的尽力服务(best effort)。随着Internet朝着提供包括数据、声音、视频等多服务统一的多媒体通讯平台发展,传统的Internet已经不能满足不同的应用在吞吐率、延迟、延迟抖动、丢失率等方面的不同要求。服务质量控制作为网络提供保证服务的手段在近十多年的时间里得到了广泛的研究。传统的服务质量研究主要基于集成服务(Intserv/RSVP)模型。这种模型的基本思想是为每一个流提供端到端的服务质量控制,它的实更多还原

【Abstract】 Due to the fast increasing in traffic and applications in Internet and the great improvement of transfer layer technology, the quality of service provision in Internet is more and more focused on scalability issue recently. Scalability should be supported in many elements in QoS architecture. Among them,the scalability in packet scheduling algorithm is of the great improtance. In this paper,we analyze the processing of packet scheduling algorithm from scalability’ s point of view. Our work suggests that the scalable packet scheduling is mainly between delay performance and other performance,such as utilization,fairness.更多还原
