Chapter 9    Quality of Service (QoS)

113

QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given 

the same priority. CoS (class of service) is a way of managing traffic in a network by grouping similar 

types of traffic together and treating each type as a class. You can use CoS to give different priorities 

to different packet types. 

CoS technologies includes DiffServ (Differentiated Services or DS). DiffServ is a new protocol and 

defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header. 

In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value ain 

a matched packet. When the packet passes through a compatible network, the networking device, 

such as a backbone switch, can provide specific treatment or service based on the tag or marker.

Use this screen to enable or disable QoS, set the bandwidth, and select to have the Device 

automatically assign priority to upstream traffic according to the IP precedence or packet length.
