Term Explanation
CTP CAPWAP Tunnelling Protocol (CTP). The Wireless AP uses a UDP (User Datagram
Protocol) based tunnelling protocol called CAPWAP Tunnelling Protocol (CTP) to
encapsulate the 802.11 packets and forward them to the HiPath Wireless Controller.
The CTP protocol defines a mechanism for the control and provisioning of Wireless APs
(CAPWAP) through centralized access controllers. In addition, it provides a mechanism
providing the option to tunnel the mobile client data between the access point and the access
controller.
DRM (dynamic radio/RF
management)
Dynamic Radio Management (DRM) functionality of the HiPath Wireless Controller is used
to help establish the optimum radio configuration for your Wireless APs. DRM is enabled by
default. The HiPath Wireless Controller’s DRM:
• Adjusts power levels to balance coverage if another Wireless AP, which is assigned to the
same SSID and is on the same channel, is added to or leaves the network.
• Allows wireless clients to be moved to another Wireless AP if the load is too high.
• Scans automatically for a channel, using a channel selection algorithm.
• Avoids other WLANs by reducing transmit power whenever other Wireless APs with the
same channel, but different SSIDs are detected.
The DRM feature is comprised of two functions:
• Auto Channel Selection (ACS) – ACS provides an easy way to optimize channel
arrangement based on the current situation in the field. ACS provides an optimal solution
only if it is triggered on all Wireless APs in a deployment. Triggering ACS on a single
Wireless AP or on a subset of Wireless APs provides a useful but suboptimal solution.
Also, ACS only relies on the information observed at the time it is triggered. Once a
Wireless AP has selected a channel, it will remain operating on that channel until the user
changes the channel or triggers ACS.
• Auto Tx Power Control (ATPC) – ATPC guarantees your LAN a stable RF environment by
automatically adapting transmission power signals according to the coverage provided by
the Wireless APs. ATPC can be either enabled or disabled.
HiPath Wireless Controller The HiPath Wireless Controller is a rack-mountable network device designed to be
integrated into an existing wired Local Area Network (LAN). It provides centralized control
over all access points (both Wireless APs and third-party access points) and manages the
network assignment of wireless device clients associating through access points.
Langley Langley is a Controller, Access Points and Convergence Software term for the inter-process
messaging infrastructure on the HiPath Wireless Controller.
Mitigator The Mitigator is a mechanism that assists in the detection of rogue access points. The feature
has three components: (1) a radio frequency (RF) scanning task that runs on the Wireless
AP, (2) an application called the Data Collector on the HiPath Wireless Controller that
receives and manages the RF scan messages sent by the Wireless AP, (3) an Analysis
Engine on the HiPath Wireless Controller that processes the scan data.
Mobility manager (and mobility
agent)
The technique in Controller, Access Points and Convergence Software by which multiple
HiPath Wireless Controllers on a network can discover each other and exchange information
about a client session. This enables a wireless device user to roam seamlessly between
different Wireless APs on different HiPath Wireless Controllers, to provide mobility to the
wireless device user.
One HiPath Wireless Controller on the network must be designated as the mobility manager.
All other HiPath Wireless Controllers are designated as mobility agents. Relying on SLP, the
mobility manager registers with the Directory Agent and the mobility agents discover the
location of the mobility manager.
