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

network segment as the device's LAN or WAN port. The gateway helps forward packets to

their destinations.

Metric

Enter the number of transmission hops (routers) that need to cross from the AMG1302/

AMG1202-TSeries to the destination.

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.

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

Section 10.6 on page 148
