Abstract	Applications that require timeliness such as; video conferencing, Voice over IP (VoIP), Video-on-Demand (VoD) etc., require quantified and well managed Quality of Service (QoS). For this, the flow label field in IPv6 header and the Label field in MPLS header should be used for efficient QoS provisioning. In this paper, flow label specifications were first investigated and then a new structure is proposed for QoS provisioning. The 20-bit field in IPv6 as well as MPLS is meant to provide QoS, other than labeling or identification purpose. But its usage is not standardized and defined that how these 20-bits must effectively be used to provide maximum possible QoS in a better way. This paper discusses it by proposing portions for QoS by explicitly specifying bandwidth, delay, and packet loss. By keeping the QoS parameters open in this way, it would be easy for a flow to decide what to reserve and how much to reserve. After that, mapping of flow label with class fields of IPv6 and MPLS is presented. In virtual networks, specially for Thin client, service quality degradation is a major issue, when IPv4-IPv6 virtual networks co-exist. This is also where this redefinition can come very handy.
