Availability
Summit WM-Series Switch Software provides seamless availability against Altitude AP outages, Summit
WM-Series Switch outages, and even network outages.
For example, if one Altitude AP fails, coverage for the wireless device is automatically provided by the
next nearest Altitude AP.
If a Summit WM-Series Switch fails, all of its associated Altitude APs, or access points, can
automatically migrate to another Summit WM-Series Switch that has been defined as the secondary or
backup Summit WM-Series Switch. When the original Summit WM-Series Switch returns to the
network, the Altitude APs automatically re-establish their normal connection with their original Summit
WM-Series Switch.
Quality of Service (QoS)
Summit WM-Series Switch Software provides advanced Quality of Service (QoS) management, in order
to provide better network traffic flow. Such techniques include:
● WMM (Wi-Fi Multimedia): enabled globally on the Altitude AP. For devices with WMM enabled.,
the standard provides multimedia enhancements for audio, video, and voice applications. WMM
shortens the time between transmitting packets for higher priority traffic. WMM is part of the
802.11e standard for QoS.
● IP ToS (Type of Service) or DSCP (Diffserv Codepoint): the ToS/DSCP field in the IP header of a
frame is used to indicate the priority and Quality of Service for each frame. The IP TOS and/or
DSCP is maintained within CTP (CAPWAP Tunneling Protocol) by copying the user IP QoS
information to the CTP header — this is referred to as Adaptive QoS.
Quality of Service (QoS) management is also provided by:
● assigning high priority to an SSID (configurable)
● Adaptive QoS (automatic)
● support for legacy devices that use SpectraLink Voice Protocol (SVP) for prioritizing voice traffic
(configurable)
