Claim:
An apparatus, comprising a control server that controls tasks that the control server assigns to a plurality of resource servers, wherein prior to assigning a task to a resource server, said control server: receives a first status message comprising parameters that includes a call gap percentage of a next overload state of a first resource server and a previous overload state of the first resource server; receives a second status message comprising parameters that includes a call gap percentage of a next overload state of a second resource server and a previous overload state of the second resource server; and wherein the control server selects which of the first and second resource servers to send a task for processing by comparing the call gap percentage of the next overload state of the first resource server and the call gap percentage of the next overload state of the second resource server, and comparing the call gap percentage of the previous overload state of the first resource server and the call gap percentage of the previous overload state of the second resource server; and the control server communicates the task to the selected resource server, wherein a call gap percentage is a percentage of call requests that are refused service.
