DSCP - Differentiated Services Code Point

The 6bit DSCP is appended to the header of an IPv4 or IPv6 packet in order to ensure the packet receives a particular forwarding treatment as it traverses a DiffServ enabled IP network. Different DSCP values will be used to apply different forwarding treatment and as such, a packet must be classified before ingress to the network to make sure that packets are given the appropriate forwarding treatment.
