IP DSCP
Differentiated Services (DiffServ) is a class of service(CoS) model that enhances best-effort Internet services by
differentiating traffic by users, service requirements and other criteria. Packet are specifically marked, allowing
network nodes to provide different levels of service, as appropriate for video playback, voice calls or other
delay-sensitive applications, via priority queuing or bandwidth allocation.
DiffServ defines a new DS(Differentiated Services) field to replace the Type of Service(ToS) field in the IP header. The DS
field contains a 2-bits unused field and 6-bits DSCP field which can define up to 64 service levels.
