Improving Quality of Server (QoS) in Voice over Internet Protocol V6 by Using Queue Technique (original) (raw)

Voice over Internet Protocol (VoIP) is develop for voice communication system that based from packet transmitted over IP network, with real-time communications for voice across networks by using the Internet protocols. Quality of Service (QoS) mechanism is applied to guarantee successful voice packets transmitted over IP network with reduced delay or drop according to assigned priority of voice packets. The objective of this research is to proposed a new approach to create Ethernet network scenario with Internet Protocol version 6 (IPv6) for VoIP and compare quality for improving quality of service (QoS) with the simulation results by using OPNET. This paper demonstrates the simulation framework based on OPNET Modeler version 14.5 is used to Improving Quality of Service (QoS) in VoIP by Using Queue Technique. In VoIP process, the performance analysis of difference queuing duplicates namely FIFO, WFQ and PQ are implemented within the OPNET simulate IPv6 along with the parameters like delay, jitter, and packets loss. The performance of the proposed algorithms is analyzed and compared the quality of service for VoIP in IPv6. The final simulate result shows that the voice traffic base on the priority and weighted-far queues were improved the quality of service for VoIP in IPv6.
