NB604 and Quality of Service (QoS)
The following Quality of Service (QoS) settings offer a basic setup example, setting up 2 devices connecting to an
NB604 router, one with the highest priority QoS priority data traffic and the other with the lowest priority QoS priority
data traffic flow. All other data packet traffic through the router assumes a default best effort setting.
Quality of Service refers to the reservation of bandwidth resources on the NB604 router to provide different priorities
to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.
In this implementation Quality of Service employs DSCP – Differentiated Services Code Point – a computer networking
architecture that specifies a simple, scalable and coarse-grained mechanism for classifying, managing network traffic.
This example guide sets up QoS with two devices (PC and laptop) connecting via ethernet cable to an NB604 router.
One device (PC) is assigned high priority traffic while the other device (laptop) is assigned a low priority. Before
Quality of Service can be implemented the first step involves reserving an IP address for each device linking the MAC
address of each device to each IP address.
