REAL TIME ESTIMATION OF EQUIVALENT BANDWIDTH UTILIZATION

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for generating via integer calculations a metric for estimating link utilization within a network device having at least one output port.

SOLUTION: 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 used for 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.
