QoS Performance Evaluation Of Video Streaming Across Ipv6

Abstract

The emerging internet video technologies provide the broadcasting industries a platform to support video streaming over the internet for viewers using the Internet Protocol version 4 (IPv4). Sequel to address shortage in IPv4, the Internet Protocol version 6 (IPv6) was invented to solve the IP addressing problem prevalent in IPv4. Meanwhile, IPv6 has not been fully deployed and it is rarely known in video streaming. This paper evaluates the Quality of Service (QoS) performance metrics of video streaming across IPv6 such as delay variation, end-to-end delay and packet loss.  In this study, the network models investigated are compatible with industrial standards and the results are validated for a scenario 1. The Network model designed involved servers, workstations, switches and routers, and other technologies for video streaming, with the key objective of examining the QoS performance metrics and the impact of QoS modifications on various parameters, and the total impact on the quality of video content transmitted across the IPV6 network. During simulation and to understand the varying effect of video frame rates and the bandwidth, the OPNET software is used in the simulation of the network model. Results of the simulation show the effect of varying the different parameters of the video frame rate and bandwidth of the network; the lesser the value of the QoS performance metrics, the better the quality of the video streamed. The results obtained quite agree with the ITU (Y.1541) and British (BS EN50132-5-1:2011) standards for video streaming.
