Abstract
A load balancer system having multiple load balancer machines working in parallel. At any given time, one of the load balancer machines is assigned to act as the current distributor that distributes web client communications and/or requests to the other load balancer machines in the load balancer system. However, these web client communications and/or requests are directed to a distributor module on all of the active, parallel load balancer machines in the system (for example, by the expedient of a common virtual IP address for layer 3/4 communications) in case the currently active distributor fails and one of the other active load balancer machines suddenly needs to take on the distributor role. In this way, web client communications are not lost when the current distributor machine fails.
