“…Several approaches are proposed in the literature [14][15][16][17], despite the use of the FL field is not fully defined. Moreover, recommendations for these approaches are confirmed by some experimental studies [31]. FL, which can increase QoS, is used with different architectures such as DiffServ [13,32].…”

“…The FL field is 20 bits long and the approach of using this field is given in Figure 5. Per hop behavior identification code (DiffServ PHB-ID) [15] is quite a good approach in terms of performance compared to others [31]. The proposed FL structure in this paper is completely different in terms of usage of the field in this structure although it is comparable to the DiffServ PHB-ID approach.…”

In the early days of the Internet architecture, the most important aim is to transmit data over packet switched networks. The traditional Internet architecture used in these networks lacks quality of service. However, today, as realtime applications increase, it is needed. There are approaches to improving the quality of service using the flow label field in the Internet Protocol version 6 header. In this study, a novel algorithm that uses destination network parameters to reduce queuing and end-to-end delay is created. A round-robin-based time-aware priority queue new model is used within this algorithm. Data packets using this proposed queue are prioritized with metric values of the destination network. In order to provide end-to-end service quality, the prioritization value is used by placing it in the flow label field. For this purpose, a new approach to the use of this field is proposed. Delay, one of the most important factors affecting quality of service, is reduced with the proposed algorithm and flow label usage approach. As a result, the reduction in delay times between 22 and 39 ms resulted in various improvement rates between 16.79% and 35.13%.

“…Several researches have concentrated on the IPv6 network performance over the last decade. There is a very large literature on general aspects of the new Internet Protocol IPv6 and its QoS evaluation are described in [10] [11] [12] [13] [14] [15] [16] [17] [18].…”

Over the last years, we have witnessed a rapid deployment of real-time applications on the Internet as well as many research works about Quality of Service (QoS), in particular IPv4 (Internet Protocol version 4). The inevitable exhaustion of the remaining IPv4 address pool has become progressively evident. As the evolution of Internet Protocol (IP) continues, the deployment of IPv6 QoS is underway. Today, there is limited experience in the deployment of QoS for IPv6 traffic in MPLS backbone networks in conjunction with DiffServ (Differentiated Services) support. DiffServ itself does not have the ability to control the traffic which has been taken for end-to-end path while a number of links of the path are congested. In contrast, MPLS Traffic Engineering (TE) is accomplished to control the traffic and can set up end-to-end routing path before data has been forwarded. From the evolution of IPv4 QoS solutions, we know that the integration of DiffServ and MPLS TE satisfies the guaranteed QoS requirement for realtime applications. This paper presents a QoS performance study of real-time applications such as voice and video conferencing in terms of Packet Delay Variation (PDV) over DiffServ with or without MPLS TE in IPv4/IPv6 networks using Optimized Network Engineering Tool (OPNET KEYWORDS DiffServ, MPLS TE, IPv6, PDV and OPNET.

“…It key benefit over IPv4 is scalability and many features of IPv6 are IPv4 "add on". IPv6 header has two QoS-related fields, the new 20-bit Flow Label field which can be used for the implementation of IntServ-based QoS schemes, and 8bit Traffic Class indicator which can be used for the implementation of DiffServbased QoS schemes (Bouras et al, 2004). The Flow Label can be used in order to identify specific flows in the network and allows intermediate nodes in the flow path to recognize the flow and treat it appropriately.…”
