IPv6 QoS Fields

• ?Traffic Class
• The traffic class field may be used to set
  specific precedence or differentiated services
  code point (DSCP) values. These values are used
  in the exact same way as in IPv4.
• Cisco Systems

• ?Flow Label
• Traffic identification using a Flow Label field
  in the IPv6 header allows routers to identify and
  provide special handling for packets belonging to
  a flow, a series of packets between a source and
  destination. Because the traffic is identified in
  the IPv6 header, support for QoS is part and
  parcel of the protocol of IPv6.
