74 WAN Load Balancing Release Note
Software Version 2.7.5
C613-10454-00 REV A
WAN Load Balancing
WAN load balancing enables you to distribute your router's wide area traffic
across two or more of its ports. Software Version 2.7.5 provides support for
WAN load balancing on AR400 series routers.
A range of traffic balancing distribution methods are provided. Basic load
balancer distribution methods are:
■ round robin distribution
■ weighted lottery distribution
On both AR400 and AR700 series routers, Software Version 2.7.5 extends the
available distribution methods to include the following:
■ weighted fast response distribution
■ weighted least connect distribution
This software version also provides healthcheck network monitoring to remote
hosts. You can employ healthcheck monitoring either to simply open or close
network paths, depending on their host's reachability status, or you can use the
healthcheck response times to adaptively balance the traffic sent through each
of the router's ports.
For information about WAN load balancing, its commands, and how to
configure it, see the WAN Load Balancing chapter at the end of this Release
Note.
