Port Triggering - ZyXEL Communications NXC5200 User Manual

WMM
Wi-Fi Multimedia (WMM) provides basic Quality of Service (QoS) features to
wireless networks. The four categories of QoS described by WMM are: voice (VO),
video (VI), best effort (BE), and background (BK). These categories, known as a
"access categories" (AC), are mapped to 802.1D priority values which can then be
mapped to their corresponding DSCP hex values.

The WMM ACs as implemented on the NXC have the following functions:
VOICE: All wireless traffic to the SSID is tagged as voice data. This is
recommended if an SSID is used for activities like placing and receiving VoIP
phone calls.
VIDEO: All wireless traffic to the SSID is tagged as video data. This is
recommended for activities like video conferencing.
BEST EFFORT: All wireless traffic to the SSID is tagged as "best effort," meaning
the data travels the best route it can without displacing higher priority traffic. This
is good for activities that do not require the best bandwidth throughput, such as
surfing the Internet.
BACKGROUND: All wireless traffic to the SSID is tagged as low priority or
"background traffic", meaning all other access categories take precedence over
this one. If traffic from an SSID does not have strict throughput requirements,
then this access category is recommended. For example, an SSID that only has
network printers connected to it.

Port Triggering

Some services use a dedicated range of ports on the client side and a dedicated
range of ports on the server side. With regular port forwarding, you set the port(s)
and IP address to forward a service (coming in from the remote server) to a client
