Evaluation of queuing algorithms on QoS sensitive applications in IPv6 network
Junaid Latief Shah, Javed Parvez · 2014
Quality of Service (QoS) is an important network performance parameter having significant impact on real time applications like VoIP, Interactive gaming and Video Streaming. Although IPv6 was designed to improve addressing, security and QoS in IPv4, services like Video Conferencing and VoIP with strong reliance and sensitivity towards delay and jitter pose a daunting challenge in today's packet based networks. These parameters must be well below the level of tolerance so that the service doesn't degrade. In this paper we discuss various parameters and dimensions on which the QoS of network depends. We also discuss the mechanisms used by IPv4 and IPv6 to implement QoS. Finally performance analysis of different queuing algorithms like FIFO, WFQ and PQ is carried out to study their impact on real time applications in IPv6 Environment. A simulation framework based on OPNET Modeler 14.5 is used to model, simulate and analyze network behavior.
