Abstract
The present invention relates to a network packet relay device including a time synchronization module for synchronizing a time of a packet with a timestamp value of a network device, and a packet timestamp assigning method thereof, wherein a timestamp having accuracy of a UTC-format nanosecond level can be assigned to the packet at a hardware level by correcting overflow of a register of an elapsed-time counter of a processor of a switch even when the overflow occurs.
