Abstract
Establishing an expected transmit time at which a network interface controller (NIC) is expected to transmit a next packet. Enqueuing, with the NIC and before the expected transmit time, a packet Pto be transmitted at the expected transmit time. Upon enqueuing P, incrementing the expected transmit time by an expected transmit duration of P. Transmitting at the NIC's line rate and timestamping enqueued Pwith its actual transmit time. Adjusting the expected transmit time by a difference between P's actual transmit and P's expected transmit time. Requesting, before completion of transmitting P, to transmit a Pat time t(P). Enqueuing, in sequence, zero or more P, such that the current expected transmit time plus the duration of the transmission of the Ps at the line rate equals t(P). Transmitting at the line rate each enqueued P. Upon enqueuing each P, incrementing, for each P, the expected transmit time by the expected transmit duration of the P. Enqueuing Pfor transmission directly following enqueuing the final P. Transmitting, by the NIC, enqueued Pat t(P).
