Clustering Configuration using Multiple APC
(WEC8500/WEC8050)
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/WEC8050 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 WEC8500/WEC8050s. 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 12 WEC8500 or maximum two WEC8050 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.
Configuration of Distributed Clustering Service
The configuration of distributed clustering is to install each WEC8500/WEC8050 in a
building or a local site according to its capacity. This option can be used when there is no
integrated backbone configuration in a site or networks are separated for each building. It
is suitable for a site where several buildings are apart from each other.
An example of service configuration diagram is shown in the below figure.
