Prioritization of packages of real-time applications on IPv6 networks according to with destination network parameters

The first and most important goal in the years when internet architecture started to occur was to transmit the data over packet-switched networks. As real-time applications such as VOIP, IPTV and video conferencing increase with the development of internet technology today, this architecture has become insufficient and various methods have been developed for QoS support those services need. However, most of these developed services were only able to provide this support only partially in the network in which they were defined. These technologies could not provide end-to-end support. Since real-time services are time sensitive, the most important factor affecting the quality of these services is delay. Improving delay values will increase service quality. IPv6, on the other hand, has brought a new approach with its Flow Label field. However, the exact rules for the use of this area are not defined. There are only approaches to the use of this area. This study proposes a prioritization model by using the routing protocol metric value of the destination network of the real-time applications as a prioritization parameter to provide end-to-end service quality required by the services and users. The IPv6 Flow Label field is used to move the prioritization value from end to end. For this, a new usage suggestion of the Flow Label field has been made and a priority-based buffer and queue model has been proposed. The designed prioritization model has been applied on four different scenarios and improvement of 13ms to 40ms has been observed on the delay values of data packets of real-time applications. These values also correspond to an improvement rate between 9.92% and 35.13%.
