摘要： Techniques for scheduling flows and links for transmission are described. Each link is an oriented source-destination pair and carries one or more flows. Each flow may be associated with throughput, delay, feedback (e.g., acknowledgments (ACKs)) and/or other requirements. A serving interval is determined for each flow based on the requirements for the flow. A serving interval is determined for each link based on the serving intervals for all of the flows sent on the link. Each link is scheduled for transmission at least once in each serving interval, if system resources are available, to ensure that the requirements for all flows sent on the link are met. The links are also scheduled in a manner to facilitate closed loop rate control. The links are further scheduled such that ACKs for one or more layers in a protocol stack are sent at sufficiently fast rates.

摘要： Methods and apparatus for extended reverse direction grant in a WLAN. In an aspect, a method includes transmitting data within a transmit interval to a plurality of the nodes, wherein the data comprises a first indicator. The method also includes receiving, in response to the first indicator, a data transmission from at least one of the nodes, wherein the data transmission was transmitted using a selected transmission resource and is received within the transmit interval. In an aspect, an apparatus includes a receiver to receive, within a time interval, first data over a common channel, the first data being decodable by other nodes. The apparatus also includes a controller to determine whether the first data comprises a first indicator, and a transmitter to transmit second data within the time interval using selected transmission resources, if the first data comprises the first indicator.

摘要： Fairness is provided among network sessions contending for available bit rate (ABR) service in an asynchronous transfer mode network by determining congestion information on a per port basis. ABR cells are monitored to determine which rate information per outgoing port based on ABR cells leaving a switch. Using the ABR per port rate, the available capacity, and the input rate to output queues, a link congestion parameter (LCP) is determined. Resource Management (RM) cells traveling through the switch are monitored to determine whether the new LCP is lower than the explicit rate (ER) field in RM cell. If the new LCP is lower, the new LCP is stuffed into the RM cell. When the sender receives the LCP value, the sender output rate is adjusted based on the LCP. Because LCP is determined based on per port traffic flow, fairness is provided among session competing for available ABR capacity.
