Basic structure

In general there are a small number of components in any load-balancing implementation, and these common elements are illustrated in figure #figloadbal#2834>.

Figure: Block structure of a load balancer

The information gathering component
This exchanges information about processor load and communications patterns of entities with other information gathering components.
The transfer component
This decides <#2843#> which<#2843#>, if any, of the processes on this node are eligible to run remotely.
The location component
This decides <#2844#> where<#2844#> the eligible processes should run.
The negotiation component
The negotiation component negotiates with negotiation components in other load balancers either to try to have processes executed elsewhere or to indicate that capacity is available on this node. It indicates to the migration manager which processes are to be moved.
