Create Quality of Service Profiles
A Quality of Service (QoS) profile defines the relative priority of an IP packet when multiple
connections are scheduled for simultaneous transmission on the UTM. A QoS profile
becomes active only when it is associated with a nonblocking inbound or outbound firewall
rule, and traffic matching the firewall rule is processed by the UTM.
After you have created a QoS profile, you can assign the QoS profile to firewall rules on the
following screens:
• Add LAN WAN Outbound Services screen (see Figure 66 on page 132).
• Add LAN WAN Inbound Services screen (see Figure 67 on page 133).
• Add DMZ WAN Outbound Services screen (see Figure 69 on page 135).
• Add DMZ WAN Inbound Services screen (see Figure 70 on page 136).
Priorities are defined by the Type of Service (ToS) in the Internet Protocol Suite standards,
RFC 1349.
There is no default QoS profile on the UTM. Following are examples of QoS profiles that you
could create:
• Normal service profile. Used when no special priority is given to the traffic. You would
typically mark the IP packets for services with this priority with a ToS value of 0.
• Minimize-cost profile. Used when data needs to be transferred over a link that has a
lower cost. You would typically mark the IP packets for services with this priority with a
ToS value of 1.
• Maximize-reliability profile. Used when data needs to travel to the destination over a
reliable link and with little or no retransmission. You would typically mark the IP packets
for services with this priority with a ToS value of 2.
• Maximize-throughput profile. Used when the volume of data transferred during an
interval is important even if the latency over the link is high. You would typically mark the
IP packets for services with this priority with a ToS value of 3 or 4.
• Minimize-delay profile. Used when the time required (latency) for the packet to reach
the destination needs to be low. You would typically mark the IP packets for services with
this priority with a ToS value of 7.
 To create a QoS profile:
1. Select Network Security > Services > QoS Profiles. The QoS Profiles screen
displays. (The following figure shows some profiles in the List of QoS Profiles table as
an example.)
