4.8.2 WMM QoS Priorities

The following table describes the priorities that you can apply to traffic that the Prestige sends
to the wireless network.

4.8.3 Services

The commonly used services and port numbers are shown in the following table. Please refer
to RFC 1700 for further information about port numbers. Next to the name of the service, two
fields appear in brackets. The first field indicates the IP protocol type (TCP, UDP, or ICMP).
The second field indicates the IP port number that defines the service. (Note that there may be
more than one IP protocol type. For example, look at the DNS service. (UDP/TCP:53) means
UDP port 53 and TCP port 53.

Chapter 4 Wireless LAN
Typically used for voice traffic or video that is especially sensitive to jitter
(variations in delay). Use the highest priority to reduce latency for improved
voice quality.
Typically used for video traffic which has some tolerance for jitter but needs to
be prioritized over other data traffic.
Typically used for traffic from applications or devices that lack QoS
capabilities. Use mid priority for traffic that is less sensitive to latency, but is
affected by long delays, such as Internet surfing.
This is typically used for non-critical "background" traffic such as bulk transfers
and print jobs that are allowed but that should not affect other applications and
users. Use low priority for applications that do not have strict latency and
throughput requirements.
