Abstract
A packet processor of a network device receives a packet and a local-domain timestamp generated for the packet at a network interface of the network device based on a local-domain clock maintained by the network device. The packet processor generates a domain-specific timestamp for the packet based on a domain-specific clock maintained by the network device, and determines a delay value using the local-domain clock. The delay value accounts for a time delay experienced by the packet between a time at which the local-domain timestamp was generated at the network interface and a time, according to the local-domain clock, at which the domain-specific timestamp is generated by the packet processor. The packet processor adjusts the domain-specific timestamp based on the delay value to generate an adjusted domain-specific timestamp for the packet, and performs at least one synchronization operation using the adjusted domain-specific timestamp.
