Destination IP
Address
This parameter specifies the IP network address of the final destination. Routing is always
based on network number. If you need to specify a route to a single host, use a subnet
mask of 255.255.255.255 in the subnet mask field to force the network number to be
identical to the host ID.
IP Subnet Mask
Enter the IP subnet mask here.
Gateway IP
Address
Enter the IP address of the gateway. The gateway is a router or switch on the same

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.

games.
10.1.2
What You Need to Know About QoS
802.1p
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. 802.1p 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 802.1p to give different priorities to
different packet types.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DiffServ Code Point (DSCP) value
and IEEE 802.1p priority level in 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.
Finding Out More
See
Section 10.6 on page 148
for advanced technical information on QoS.
