Session Load Balancing
You can assign DWL-8220AP access points to a load-balancing group. A load-balancing
group helps reduce congestion by distributing client sessions among the access points in the
group. For example, if an 802.11b/g radio operating on channel 1 is supporting more sessions
than a neighboring 802.11b/g radio operating on channel 6, the loadbalancing feature can
reject association requests to the radio on channel 1.
To balance the sessions, MSS rejects an association request for an access point's radio if
that radio has at least four more active sessions than the radio of the same type with the
least number of active sessions within the group. If the rejected client associates with another
access point in the same group, the session load among the access points in the group
becomes more balanced.
Load balancing is based only on association requests for new sessions. Adding an access
point to a group does not affect sessions that are already active on the access point. In
addition, MSS does not attempt to rebalance sessions when a client disassociates from an
access point. If MSS rejects an association request for load-balancing reasons but not for
authentication reasons, the rejection does not count as an authentication failure.
D-Link recommends that you configure small groups and ensure that all the radios in the
group provide comparable coverage within the same service area.
Service Profiles
A service profile controls advertisement and encryption for an SSID. You can specify the
following:
• Whether SSIDs that use the service profile are beaconed
• Whether the SSIDs are encrypted or clear (unencrypted)
• For encrypted SSIDs, the encryption settings to use
• The fallthru authentication type for users that are not authenticated with 802.1X or
MAC authentication
The table below lists the parameters controlled by a service profile and their default values.
