Quality of Service (QoS)
10.1 Overview
Use the
QoS
screen to set up your AMG1302/AMG1202-TSeries to use QoS for traffic management.
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and
the networking methods used to control bandwidth. QoS allows the AMG1302/AMG1202-TSeries to
group and prioritize application traffic and fine-tune network performance.
Without QoS, all traffic data are equally likely to be dropped when the network is congested. This
can cause a reduction in network performance and make the network inadequate for time-critical
applications such as video-on-demand.
The AMG1302/AMG1202-TSeries assigns each packet a priority and then queues the packet
accordingly. Packets assigned with a high priority are processed more quickly than those with low
priorities if there is congestion, allowing time-sensitive applications to flow more smoothly. Time-
sensitive applications include both those that require a low level of latency (delay) and a low level
of jitter (variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which
jitter alone is a problem such as Internet radio or streaming video.
In the following figure, your Internet connection has an upstream transmission speed of 50 Mbps.
You configure a classifier to assign the highest priority queue (6) to VoIP traffic from the LAN
interface, so that voice traffic would not get delayed when there is network congestion. Traffic from
the boss’s IP address (192.168.1.23 for example) is mapped to queue 5. Traffic that does not
match these two classes are assigned priority queue based on the internal QoS mapping table on
the AMG1302/AMG1202-TSeries.
