QoS Tab

QoS (Quality of Service) allows you to prioritize network traffic using either Application-based priority (such as

Web browsing applications, FTP applications, etc.) or Port-based priority, which allows you to assign priorities to

the four physical network ports. Higher priority traffic will be allocated more bandwidth, which results in lower

latency (or delay).

Application-based

The Application-based QoS controls priority differentiation for data packets between LAN (including WLAN) and

WAN ports. Application-based QoS is achieved by software running on the CPU so it cannot control traffic

between LANs that are switched directly by a hardware switch chipset.

Application-based QoS. QoS (Quality of Service) is disabled by default. When enabled, this option allows you to

assign priority based on the application type.

Set Internet Bandwidth. Enter approximate bandwidth number for your WAN connection. This will help the

software-based algorithm to allocate bandwidth to different priorities.

• Select the desired option for each application: High priority, Medium priority, or Low priority.

Table 1: Application-based QoS

Application

Name

Port(s) Primary Use

FTP TCP Port 20 FTP (File Transfer Protocol) is used for transferring files over the Internet.

HTTP TCP Port 80 HTTP (HyperText Transfer Protocol) is used for browsing the Internet.

Telnet TCP Port 23

Telnet is a client-server protocol used to communicate over a network or

the Internet.

SMTP TCP Port 25 SMTP (Simple Mail Transfer Protocol) is used for sending e-mail.

POP3 TCP Port 110 POP3 (Post Office Protocol version 3) is used for retrieving e-mail.

Specific Port User Defined User Defined (0-65535)

Figure 6-47: QoS - Application Based

IMPORTANT: If you don’t assign different priorities to applications, there will be

no differentiation between different traffic types.
