Clustering Configuration Using Multiple Apc (Wec8500) - Samsung WEC8500 Operation Manual

2600-00FK1RGA4 Ver.
In this configuration, several APC s are used to minimize service disruption caused by a
disconnected APC and to enhance service sustainability. Basically, two or more APC s
must be installed in the same site for APC redundancy. The redundancy configuration
includes active-active configuration, active-standby configuration, and many-to-one
configuration. An operator can select a configuration based on the number of available
APC s and redundancy level.

Clustering Configuration using Multiple APC (WEC8500)

The W-EP environment has various area sizes, user density and number of users. If only a
single APC is required for service and management, the complexity of network
configuration or management is not high. However, if the capacity of a single APC is not
sufficient, multiple APC s must be installed for service. The WEC8500 is a Samsung APC
model providing the clustering environment.
To set up a wireless LAN network in an environment where multiple WEC8500s are
installed, the integrated management system and user service must be provided through
clustering configuration between the WEC8500s. This allows inter APC handover.
The WEC8500s configured in a cluster provides a service just like a single WEC8500
through periodic information exchange.
Inter APC handover
The inter APC handover is a handover between APCs. A clustering group is used
to provide this function and this clustering group means a virtual area.
Maximum six WEC8500s can be bound to a single group. An APC in a group
cannot be added to another group.
It provides layer 3 handover and the handover is supported when a terminal moves to
an APC which have different subnets. A serving APC is called as an anchor APC
and a target APC is called as a foreign APC. The control path and also the tunnel
for data traffic between APCs provide security using IPSec.
The inter APC handover provides this function both in the standard Wi-Fi
handover and Samsung's unique AirMove method.
