Abstract: A method including configuring a transmit process to store information including a queue of packets to be transmitted, the queue defining transmit process packets to be transmitted, each packet associated with a transmission time, and configuring a synchronization process to receive from the transmit process at least some of the information. The synchronization process performs one of: A) accessing a dummy send queue and a completion queue, and transmitting one or more of the transmit process packets in accordance with a completion queue entry in the completion queue, and B) sends a doorbell to transmission hardware at a time when at least one of the transmit process packets is to be transmitted, the synchronization process including a master queue configured to store transmission entries, each transmission entry including a transmit process indicator and an indication of transmit process packets to be transmitted. Related apparatus and methods are also described.
