Packet Scheduling Algorithms Simulator WFQ SCFQ And WF2Q

Abstract As the Internet evolves into the global communication infrastructure there is a growing need to provide a broad range of QoS guarantee for different applications which brings forth the necessity of traffic management. The scheduling algorithm in the router determines how packets from different connections interact with each other by controlling the order in which packets are served. As one of the most important parts in traffic management the packet scheduling plays an important role in the QoS provisions. The Packet Scheduling is the shared transmission resources should be intentionally assigned to some of the users at given time. The process of assigning users packets to appropriate shared resources to achieve some performance guarantee is so called Packet Scheduling which is done by the fair queueing methods.
