A comparative analysis of basic and hybrid queuing methods and their impact on the VoIP traffic delay within the network have been discussed in this paper. In this experiment the hybrid queuing method is formed by combining three of the most useful basic queuing methods. In basic queuing methods priority queuing (PQ), custom queuing (CQ) and weighted fair queuing (WFQ) are combined with class-based weighted fair queuing (CBWFQ) for hybrid queuing. Hybrid method is compared with the basic method. All the basic and hybrid queuing mechanisms are tested using an OPNET Modeler simulation tool. From this, it is found how queuing combinations affect VoIP traffic quality, especially QoS.
