QUALITY OF SERVICE

Quality of Service
QoS (Quality of Service) prioritizes incoming data, and prevents data loss due to factors such as jitter, delay, and
dropping. QoS helps to prioritize data as it enters your router. By attaching special identification marks or headers
to incoming packets, QoS determines which queue the packets enter, based on priority.

QoS Configuration

Before QoS can work correctly, this gateway needs to know available bandwidth of WAN connection.
■
Bandwidth of Upstream: Input the maximum bandwidth of uplink in Kbps.
■ Bandwidth of Downstream: Input the maximum bandwidth of downlink in Kbps.
■ Flexible Bandwidth Management: It is recommended you enable this option to exploit maximum
bandwidth effectively.

Rule-based QoS

This gateway provides lots of flexible rules for you to set QoS policies.

Create a QoS Rule

■
Rule: Check this if you want to activate this rule after it's created.
■
Grouping: There are two methods to define "who" will be managed, base on IP address or MAC address.
If creating a rule by IP address:
■ Grouping: Choose IP from the list, and indicate single IP address or a segment IP range in following
field.
■
Service: Define the type of service that needs to be managed. There are four options for service
recognition.
■ DSCP: DiffServ Code Point, as known as advanced TOS. You can choose this option if your local
service gateway supports DSCP tags.
■
Service Port: Input a service port number or a segment of port range manually. You also need to
indicate it's TCP or UDP service.
■
Pre-defined Application profiles: This option is similar to Service Port, but lists many well-known
services for your reference.
■ Connection Sessions: Choose this option if you want to limit connection sessions on those selected
hosts.
■
Control: Set the corresponding control types for the selected service type.
■
DSCP Marking: This option is only available when DSCP is chosen in Service field. The purpose of this
option is changing original DSCP tag to a new value. This option won't prioritize data packets.
■ PRI: Set priorities for data packets of selected hosts. The value is from 1 to 6. "1" is with highest
priority, and "6" is with least priority.
■
MAXR: Indicate the maximum bandwidth for selected hosts. The measurement unit can be Kbps or
Mbps.
■
MINR: Indicate the minimum bandwidth for selected hosts. The measurement unit can be Kbps or
Mbps.
