Configuration Guide How to Configure QoS (Quality of Service) on Omada Router
This Article Applies to:
All routers with Gateway QoS function.
Application Scenario:
Configuration Mindnote:
First things first, get to know what should be done before you start to configure.
QoS Deployment:
1. Determining Overall Strategy for the QoS
2. Identify QoS Service and Non-QoS Service
3. Queuing Model
4. Bandwidth Assignment
QoS Effect Evaluation:
1. Evaluating Service Quality
2. Evaluating QoS Strategy
3. Analyzing Traffic
4. Quality-Checking of QoS
5. Conducting Overall Evaluation
6. Adjusting QoS
Configuration Steps:
1. Identify the goal of QoS and the service involved in QoS.
2. Select your Organization and choose your Site.
3. Go to Settings > Transmission > Gateway QoS.
4. Configure a new rule in Bandwidth Control.
Note:
1. In most cases, QoS does not significantly affect regular internet usage for home users.
2. While high-bandwidth ISPs may make it difficult to perceive the benefit of QoS, it can be highly beneficial for prosumers or business users with dedicated connections where the bandwidth is not high.
3. Pay attention to that you should set the parameters based on your needs. In this setup, certain parameters are not enabled.
4.1. Inbound Bandwidth and Outbound Bandwidth should be set correctly based on your Internet plan. Or it might affect your network speed.
4.2. The Percentage for each Class should be set based on your needs.
4.3. Configure your WAN Interface and corresponding parameters as specified above. Click Create.
5. Go to Profiles > Gateway QoS Service > Create New Gateway QoS Service.
Since we use iperf and the port is default 5201, we create a new one and save it.
6. Go to Class Rule > Create New Class Rule.
We create two rules here.
7. (Optional) To prioritize VoIP traffic, enable the VoIP Prioritization feature and specify the SIP UDP port for high-priority transmission.
Note: we did not have VoIP devices in this setup. It is listed for demonstration.
8. (Optional) Go to Tag Outbound Traffic. You can tag the outbound traffic so this will be helpful for other devices to identify the traffic accordingly. It is especially useful in a network where QoS is properly configured.
Note:
Router QoS Configuration: Routers are typically used to connect different networks and manage traffic entering and leaving a network. Configuring QoS on a router can help manage different types of traffic to ensure that important data (such as VoIP calls) is prioritized. Routers can identify different types of traffic and prioritize or limit certain traffic based on configurations. When a router is configured with QoS and tags outbound traffic, it usually does so by setting the DSCP (Differentiated Services Code Point) field in the IP packet header.
Switch QoS Configuration: Switches are primarily used within a network to connect multiple devices, such as computers, printers, etc. Some advanced switches also support QoS and can recognize and prioritize tagged traffic. If your network involves applications sensitive to latency, such as VoIP or video conferencing, and this traffic needs to be transmitted within the internal network, then configuring QoS on switches may be necessary. Switches can manage traffic based on the DSCP values tagged by routers or other criteria (such as port numbers).
