Cell transfer rate regulation using feedback in nominal bit rate (nbr) system

摘要

A system and method for regulating the cell transfer rate over a network in response to priority level feedback. The feedback feature provides network connection availability information corresponding to a level of bandwidth available on the network connection to the cell source. The connection availability information is converted into a buffer occupancy level accessible at the cell source. The cell transfer rate is regulated at the network source unit in accordance with the buffer occupancy level, including decreasing the cell transfer rate when the buffer occupancy level rises above a high occupancy threshold of the buffer, and increasing the cell transfer rate when the buffer occupancy level drops below a low occupancy threshold of the buffer.
