Abstract: In some embodiments, an apparatus includes a transmission schedule module in at least one of a memory or a processing device that can select, at a first time, a data unit to send to a network device based at least in part on a value of a transmission rate counter indicating that the network is in a first state. The transmission schedule module can receive, at a second time, an indication of a number of buffers associated with the data unit and can calculate a size estimate of the data unit based on the number of buffers and a capacity associated with each buffer. The transmission schedule module can calculate at a third time, a temporary transmission rate count and can send a signal to transition the network device from the first state to a second state if the temporary transmission rate count meets a criterion.

Abstract: An apparatus for increasing scheduling efficiency in network devices may include (1) at least one memory device that stores at least one data chunk included in a packet, (2) a scheduler device that (a) schedules transmission of the packet that includes the data chunk and (b) issues a request to transmit the packet based at least in part on the scheduled transmission, and (3) a packet-delivery device that (a) receives the request to transmit the packet from the scheduler device, (b) prepares the packet for transmission at a faster rate than the scheduler device schedules the transmission of the packet, and then (c) facilitates transmitting the data chunk included in the packet to a computing device. Various other apparatuses, systems, and methods are also disclosed.
