1. A method, comprising: maintaining, by processing circuitry, statistics relating to slice allocation in connection with like system resources; receiving, by processing circuitry and from a requesting entity, a request for allocation of a resource; in response to receiving the request, selecting, by processing circuitry and for a particular slice class, a best system resource based on the statistics to implement a policy; and allocating, by processing circuitry, a slice for the particular slice class in connection with the best system resource; wherein selecting the best system resource, comprises: determining a first value in connection with a first system resource of the like system resources, wherein the first value relates to total slice allocation in connection with the first system resource; adjusting the first value by a pre-determined amount to produce an adjusted first value; determining a second value in connection with a second system resource of the like system resources, wherein the second value relates to total slice allocation in connection with the second system resource; comparing the adjusted first value and the second value; and based on the said comparison, selecting, for the particular slice class, one of the first and the second system resources as the best system resource to implement the policy.
