Atc+Wmm; Atc+Wmm From Lan To Wlan - ZyXEL Communications NWA-3160 User Manual

Chapter 8 Wireless Screen
When ATC is activated, the device sends traffic with smaller packets before traffic
with larger packets if the network is congested.
ATC assigns priority to packets as shown in the following table.
Table 26 Automatic Traffic Classifier Priorities
PACKET SIZE
(BYTES)
1 ~ 250
250 ~ 1100
1100 +
You should activate ATC on the NWA if your wireless network includes networking
devices that do not support WMM QoS, or if you want to prioritize traffic but do not
want to configure WMM QoS settings.

8.3.3 ATC+WMM

The NWA can use a mapping mechanism to use both ATC and WMM QoS. The
ATC+WMM function prioritizes all packets transmitted onto the wireless network
using WMM QoS, and prioritizes all packets transmitted onto the wired network
using ATC. See
ATC+WMM.
Use the ATC+WMM function if you want to do the following:
• enable WMM QoS on your wireless network and automatically assign a WMM
priority to packets that do not already have one (see
128).
• automatically prioritize all packets going from your wireless network to the
wired network (see

8.3.3.1 ATC+WMM from LAN to WLAN

ATC+WMM from LAN (the wired Local Area Network) to WLAN (the Wireless Local
Area Network) allows WMM prioritization of packets that do not already have WMM
QoS priorities assigned. The NWA automatically classifies data packets using ATC
and then assigns WMM priorities based on that ATC classification.
