1. A method of selecting to which of a plurality of X different subscriber resources a call is to be routed to in a subscriber network system having a processor utilizing a routing algorithm for selecting one such resource, comprising the steps of:

  • selecting a desired distribution of calls among said X resources, the desired distribution representing a percentage of calls to be routed to each of said X resources;

    upon receiving a call to be routed, then for each such call calculating X simulated distributions, one associated with each said resource, each such simulated distribution being calculated assuming that the call is to be selected to be routed to its associated said resource and not to the other resources, each said X simulated distributions representing a percentage of calls actually and assumed to have been routed to each of said X resources, whereby for each simulated distribution the percentage for its associated said resource increases and the percentage for each of the other resources decreases;

    comparing each of said X simulated distributions to the desired distribution by comparing the percentages of the desired distribution to the percentages of each of the X simulated distributions for each of said X resources to determine a best distribution, the best distribution being the simulated distribution closest to the desired distribution; and

    selecting the resource associated with the best distribution for routing the call.
