New applications such as VoIP, e-commerce and video conferencing are sensitive to network performance, making the network capacity to provide quality of service is increasingly important. IPv6 was developed to solve some of the problems of IPv4, such as QoS, security and IP address exhaustion. Current IP networks provide better trafficdelivery effort, therefore, offer no guarantee of quality service. However, there are services, including voice, with stringent requirements for delay and delay variation (jitter), which makes it necessary to add functionality to IP networks based on this protocol are capable of supporting such services. For its part, IPv6 uses 2 fields that can be used to implement QoS, which are: Flow Label and Traffic Class. This article describes the mechanisms and architectures that are used to provide QoS on a network. Later, you specify the features that use both IPv4 and IPv6 to implement QoS. In the last sections present the results of the comparison of 2 scenarios, which are evaluated.
