About the HiPath Wireless Standalone Access Point
About clustering
●
Wi-Fi Protected Access version 1 (WPA v.1) – A security protocol with Temporal Key
Integrity Protocol (TKIP) that provides Pre-shared Master Key management, and a WEP
128-bit cipher. The WPA v.1 protocol provides good security.
●
Wi-Fi Protected Access version 2 (WPA v.2) – A security protocol with Advanced
Encryption Standard (AES) that provides Pre-shared Master Key management, and an
AES 128-bit cipher. The WPA v.2 protocol provides the best security. It is highly
recommended to use WPA v.2.
●
Media Access Control address(MAC) – In addition, MAC address filters are used in
securing the network. Authentication by MAC address provides a method of access control
for a user as it associates with the access point based on the device's MAC address.
3.2.3 About Quality of Service
The Standalone Access Point provides advanced Quality of Service (QoS) management in
order to provide better network traffic flow. Such standards include:
●
WMM (Wi-Fi Multimedia) – Enabled per VNS on the Standalone Access Point. For
devices with WMM or 802.1e enabled, the standard provides multimedia enhancements
for audio, video, and voice applications. WMM and 802.11e shorten the time between
transmitting packets for higher priority traffic.
●
IP ToS (Type of Service) or DSCP (Diffserve Codepoint) – The ToS/DSCP field in the
IP header of a frame is used to indicate the priority and QoS for each frame.
●
802.11e – If enabled, the Standalone Access Point will accept 802.11e client associations,
and will classify and prioritize the downlink traffic for all 802.11e clients. 802.11e clients will
also classify and prioritize the uplink traffic.
When Priority Override is enabled, the configured User Priority will determine the transmit
queue and the user priority for the wireless QoS packets (WMM or 802.11e) in the downlink
direction. The User Priority value is also used to tag the VLAN Priority field for the uplink
traffic if the VLAN tagging is enabled for this VNS.
3.3 About clustering
The Standalone Access Point must operate in cluster setup. The purpose of the cluster is to
limit the number of access points in it, and to enable roaming. Secure Inter-Access Point
Protocol (SIAPP) is used to build cluster information in each access point. All access points in
the same roaming cluster must be on the same subnet.
