摘要

网络应用对服务质量的要求是提高呼叫质量和用户满意度。因此,在网络中的交换机和路由器上实现排队规则将控制数据包在等待传输时的缓冲方式。诸如先进先出(FIFO)队列、优先级队列(PQ)、加权公平队列(WFQ)、自定义队列和改进加权轮询等队列规则在网络应用中得到了更突出的部署。这些排队规则通过为网络上特定类型的数据确定优先级来帮助控制和管理网络资源。本文旨在分析文件传输协议(FTP)、电子邮件、数据库、IP语音(VOIP)、视频和网页浏览等各种实时应用的服务质量参数。,并有助于优化现有网络资源的使用。此外,还使用端到端延迟、吞吐量、抖动和平均意见评分(MOS)等不同的QoS参数对网络质量进行了比较。本文主要研究了低网络流量和高网络流量下的各种排队问题。

IMPACT OF QUEUING DISCIPLINES ON THE PERFORMANCE OF MULTI-CLASS TRAFFIC IN A NETWORK
Network applications demand quality of service for enhanced call quality and increased user satisfaction. Hence, implementing queuing discipline at switches and routers in a network will govern the way packets are buffered while waiting for transmission. Queuing disciplines like first-in first-out (FIFO) queuing, priority queuing (PQ), weighted-fair queuing (WFQ), custom queuing and modified weighted round robin are more prominently deployed in network applications. These queuing disciplines help to control and manage network resources by fixing priorities for specific types of data on the network. The paper aims to analyze the quality of service parameters for various real time applications like File transfer protocol(FTP), email, database, Voice over IP(VOIP), video and web browsing,etc., and helps to optimise the use of available network resources. Moreover the quality of the network is compared using different QoS parameters such as end-to-end delay, throughput, jitter and Mean Opinion Score (MOS). This paper focuses on various queuing disciplines with low and high network traffic.
