Abstract

System and methods for providing quality of service (QOS) in networks. The method includes determining whether a transmit segment of a port of a network device has received a grant from a scheduler to transmit a packet. The port includes a plurality of sub-ports that share the transmit segment to transmit packets and a receive segment to receive packets. When the transmit buffer has received the grant, a virtual queue associated with the grant is mapped to a QOS bin that includes a minimum bandwidth limit threshold value, a maximum bandwidth threshold value, and a counter for counting actual bandwidth consumed. The QOS bin monitors bandwidth consumed by a source traffic group for adjusting QOS priority and the source traffic group includes the virtual queue.
