Abstract
An apparatus and method for generating via integer calculations a metric for estimating link utilization within a network device having at least one output port. The metric is determined by calculating at least three data rate link parameters for a given sampling period. The data rate link parameters include an error data rate parameter, an average data rate parameter, and a deviation data rate parameter. These parameters are determined using integer values and integer operations and may be used by a link management system for performing load balancing among a plurality of output ports and for determining whether to forward low priority data traffic via a particular output port.
