Title: Buffer-based traffic measurement system and method for nominal bit rate (NBR) service

Abstract: A system and method for controlling the cell priority of cells transmitted from a cell source to network destinations across a network connection is provided. Each of the cells transmitted is registered in a measurement buffer upon being output from the cell source. The registered cells in the measurement buffer are discharged at a discharge rate corresponding to the current occupancy level of the measurement buffer. Cell priority values are generated by correlating the current buffer occupancy level to one of a plurality of predetermined buffer occupancy ranges to determine which occupancy range coincides with the current occupancy level. The generated cell priority values are loaded into cells transmitted from the cell source for use by the network connection.
