Modeling and Simulation of Queuing Scheduling Disciplines on Packet Delivery for Next Generation Internet Streaming Applications

Internet users around the world depend on various computer networks services such as video-conferencing, FTP and VoIP as a next generation Internet applications. This paper presents performance analysis of different queuing scheduling disciplines for Internet applications and services using OPtimized Network Engineering Tool (OPNET). Mainly, the authors focus on various queuing scheduling disciplines including Modified Weighted Round Robin (MWRR), First In-First Out (FIFO), Priority Queuing (PQ) and Weighted Fair Queuing (WFQ). This modeling and simulation are based on the effects of these queuing scheduling disciplines on packet delivery for three next generation Internet streaming applications: File Transfer Protocol (FTP), video-conferencing and Voice over Internet Protocol (VoIP).
