Abstract
A method for improving network server load balancing in a system that has a plurality of network servers connected by an Internet access LAN to the Internet, a back-end access LAN connected to several database servers, and a network load balancer for selecting one of the network servers according to weights associated with the network servers. Link connectivity is monitored cyclically from each network server, and a status indicator is set to UP if all of the links associated with the network server are available, or to DOWN if at least one link is unavailable. The network servers send their status indicators to the network load balancer. The network load balancer changes the weight associated with a network server to a non-eligible value if the associated status indicator changes from UP to DOWN.
