Abstract
In one embodiment, a network interface controller (NIC) includes multiple packet transmission queues to queue data packets for transmission. The data packets are assigned to multiple traffic classes. The NIC also includes multiple input/output (I/O) interfaces for retrieving the data packets from memory. Each I/O interface is assigned to a subset of the traffic classes. The NIC also includes scheduler circuitry to select a first data packet to be retrieved from memory, and direct memory access (DMA) engine circuitry to retrieve the first data packet from memory via one of the I/O interfaces based on the traffic class of the first data packet, and store the first data packet in one of the packet transmission queues. The NIC also includes a transmission interface to transmit the first data packet over a network at a corresponding launch time indicated by the scheduler circuitry.
