Abstract
Systems and methods for synchronizing clocks across networks using a time-sensitive (TS) network interface controller (NIC). The TS NIC may include a functional unit, a port, a clock, a plurality of input/output queue pairs, and a time stamp unit (TSU). The functional unit may be configured to generate synchronization packets usable by an NTS network timekeeper of a respective NTS network to synchronize the NTS network to the master clock, including using the TSU to generate time stamps for the synchronization packets in accordance with the clock synchronized to the master clock and communicate with the respective NTS network via the port using the corresponding input/output queue pair, including sending the synchronization packets to the NTS network timekeeper of the respective NTS network.
