3.6.1.4 AP Load Balancing
Several APs can form a load-balancing group if they are set with the same
‘Group ID’. The load-balancing policy can be by ‘Number of Users’ or by
‘Traffic Load’.
If the ‘Number-of-Users’ policy is selected, a new wireless user can only
associate with an AP that has the smallest number of associated wireless
users in the group. On the other hand, if the ‘Traffic-load Policy’ is selected, a
new wireless user can only associate with an AP that has the less traffic load
in the group.
3.6.1.5 Wireless Distribution System
Traditionally, access points are connected by Ethernet. By Wireless
Distribution System (WDS), APs can communicate with one another
wirelessly. For example, in the below diagram, AP 2 acts as an access point
for the notebook computers and it forwards packets sent from the notebook
computers to AP 1 through WDS. Then, AP 1 forwards the packets to the
Ethernet LAN. Packets destined for the notebook computers follow a reverse
path from the Ethernet LAN through the APs to the notebook computers. In
this way, AP 2 plays a role of “AP repeater”.
