Attack Checks - NETGEAR FVS318G - ProSafe Gigabit VPN Firewall Data Sheet Router Reference Manual

The QoS priority definition for a service determines the queue that is used for the traffic passing
through the VPN firewall. A priority is assigned to IP packets using this service. Priorities are
defined by the "Type of Service (ToS) in the Internet Protocol Suite" standards, RFC 1349. A ToS
priority for traffic passing through the VPN firewall is one of the following:
• Normal-Service. No special priority given to the traffic. The IP packets for services with this
priority are marked with a ToS value of 0.
• Minimize-Cost. Used when the data must be transferred over a link that has a low
transmission cost. The IP packets for this service priority are marked with a ToS value of 1.
• Maximize-Reliability. Used when data needs to travel to the destination over a reliable link
with little or no retransmission. The IP packets for this service priority are marked with a ToS
value of 2.
• Maximize-Throughput. Used when the volume of data transferred during an interval is
important even if the latency over the link is high. The IP packets for services with this priority
are marked with a ToS value of 4.
• Minimize-Delay. Used when the time required for the packet to reach the destination must be
short (low link latency). The IP packets for this service priority are marked with a TOS value
of 8.
