QoS/DSCP (the DiffServ model)
DSCP-ECN denes QoS at Layer 3 (Network Layer). The Differentiated Services (DiffServ) model
is based on packet marking and router queuing disciplines. The marking is done by adding a eld
to the IP header, called the DSCP (Differentiated Services Codepoint). This is a 6-bit field that
provides 64 different class IDs. It gives an indication of how a given packet is to be forwarded,
known as the Per Hop Behavior (PHB). The PHB describes a particular service level in terms of
bandwidth, queueing theory, and dropping (discarding the packet) decisions. Routers at each
network node classify packets according to their DSCP value and give them a particular forwarding
treatment; for example, how much bandwidth to reserve for it.
Below are the setting options of DSCP (DiffServ Codepoint). Specify the DSCP value for each
application (0~63).
