Abstract: A network device, including ports that receive/send data packets from/to a network, receives data packets of multiple traffic flows, and populates a queue in memory with the data packets. The network device periodically updates a fair rate for the multiple traffic flows to converge a length of the queue to a reference length. Specifically, the network device determines a length of the queue, a change in the length from a previous length, and a deviation of the length from the reference length. The network device detects an increase in the change in length above a threshold that is based on the reference length. If the increase is not above the threshold, the network device derives the fair rate from a previous fair rate using proportional integral control. The network device identifies elephant flows among the multiple traffic flows, and sends the fair rate to a source of each elephant flow.

Abstract: A method for controlling access to a wireless Access Network (AN) by a wireless communication device. The device stores a Device Access Priority (DAP) level based on characteristics of the device. When the device has data to send, the device receives an overhead message from the AN containing a Network Access Priority (NAP) parameter defining a minimum priority level for initiating network access. The device determines whether its DAP level is equal to or greater than the NAP parameter. If not, the device periodically repeats the receiving and determining steps until the stored DAP level is determined to be equal to or greater than the NAP parameter received from the AN. When the stored DAP level is equal to or greater than the NAP parameter, the device initiates network access. The device may perform and pass a Persistence Test before transmitting the data on an access channel (ACH).
