With load balancing

A load balancer is a network device that not only distributes specific client traffic to

specific servers, but also periodically checks the status of a proxy to ensure it is

operating properly and not overloaded. This monitoring activity is different from

simple load distribution, which routes traffic but does not account for the actual traffic

load on the proxy.

A load balancer can detect a proxy failure and automatically re-route that proxy’s

traffic to another, available proxy. The load balancer also handles virtual IP address

assignments. The following figure shows a load balancer added to an explicit proxy

configuration:
