Performance Analysis of IPv6 QoS for Multimedia Applications Using Real Testbed

IPv6 is intended to provide better network QoS than IPv4, however, service providers still lacking confidence to claim this. The reason lies in less IPv6 QoS mechanisms, evaluation for several challenging scenarios, i.e. live streaming and video conferencing, etc. In this paper, to overcome this issue, we focus on evaluation of IPv6 QoS mechanism i.e. Traffic Class (TC) on real testbed. For Traffic Class (TC) evaluation, several scenarios are implemented with different DSCP values i.e Default PHB (Per hop behavior), Assured Forwarding (AF), Class Selector and Expedited Forwarding (EF). For evaluation, several test cases are devised with a combination of multiple DSCP values of the above four categories.
