Differentiated Services

This chapter shows you how to configure Differentiated Services (DiffServ) on the Switch.

26.1  DiffServ Overview 

Quality of Service (QoS) is used to prioritize source-to-destination traffic flows. All packets in 
the flow are given the same priority. You can use CoS (class of service) to give different 
priorities to different packet types.
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-
hop treatment at DiffServ-compliant network devices along the route based on the application 
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the 
level of service desired. This allows the intermediary DiffServ-compliant network devices to 
handle the packets differently depending on the code points without the need to negotiate paths 
or remember state information for every flow. In addition, applications do not have to request 
a particular service or give advanced notice of where the traffic is going. 

26.1.1  DSCP and Per-Hop Behavior 

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 6-bit DSCP field which can define up to 64 
service levels and the remaining 2 bits are defined as currently unused (CU). The following 
figure illustrates the DS field. 

Figure 109   

DiffServ: Differentiated Service Field 

DSCP is backward compatible with the three precedence bits in the ToS octet so that non-
DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. 
The DSCP value determines the PHB (Per-Hop Behavior), that each packet gets as it is 
forwarded across the DiffServ network. Based on the marking rule different kinds of traffic 
can be marked for different priorities of forwarding. Resources can then be allocated 
according to the DSCP values and the configured policies. 

DSCP (6 bits) 

CU (2 bits)
