QoS Policy

240 HiPath Wireless Controller, Access Points and Convergence Software V7.11, User Guide
Enterprise – Specifies 802.1x authentication and requires an
authentication server
Pre-Shared Key (PSK) – Relies on a shared secret. The PSK is a shared
secret (pass-phrase) that must be entered in both the Wireless AP or
router and the WPA clients.
Note: To achieve the strongest encryption protection for your VNS, it is
recommended to use WPA v.1 or WPA v.2.
5.9 QoS Policy
The HiPath Wireless Controller, Access Points and Convergence Software
solution provides advanced Quality of Service (QoS) management to provide
better network traffic flow.
The HiPath WLAN distinguishes between two levels of QoS treatment applied to
the client traffic: wireless and wired. Wireless QoS is applied at the APs, while the
wired QoS is applied at both the APs and the HiPath Wireless Controller. QoS
definition and configuration are part of the WLAN Services specifications.
On the wired side, a class of service can define DSCP and IP/TOS markings that
can overwrite the markings in the ingress frame. A class of service can specify
the transmission queuing behavior that is applied to frames.
Rate limiting can also be considered part of overall QoS specification. Rate
limiting/control is applied to all traffic assigned to a policy.
5.10 Flexible Client Access (FCA)
Flexible client access provides the ability to adjust media access fairness In five
levels between Packet Fairness and Airtime Fairness.
Packet Fairness is the default 802.11 access policy.
Each WLAN participant gets the same (equal) opportunity to send
packets.
All WLAN clients will show the same throughput regardless of their PHY
rate.
WLAN clients with lower PHY rates will occupy most of the airtime.
Example of packet fairness:
2 clients @ 300Mbps get media access equivalent to a PHY rate of
150Mbps each = 300Mbps total
