Estimating equivalent bandwidth capacity for a network transport device using on-line measurements

摘要

A method and apparatus are described for determining an equivalent capacity of a transport device in a network switch for a traffic data stream. A data collector collects at least one traffic parameter for the traffic data stream arriving at a queue of the transport device for a specified quality of service (QoS) class. A bandwidth estimator is coupled to the data collector to estimate an effective bandwidth using the at least one traffic parameter. The estimated effective bandwidth corresponds to the equivalent capacity of the transport device.
