Abstract: The present invention relates to: a network packet intermediary device comprising a deep packet matching module for matching a GTP control plane packet and a GTP user plane packet by controlling a GTP correlation module; and a deep packet matching method thereof, and can extract packet information of a deep step from a switch level so as to match flows of the GTP control plane packet and the GTP user plane packet, and can provide a correlation so that the GTP control plane packet and the GTP user plane packet can be transmitted to the same outlet port.

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.

Abstract: The present invention relates to a network packet broker device including a deep packet matching module which controls a GTP correlation module to match a GTP control plane packet and a GTP user plane packet and a deep packet matching method thereof. Packet information in a deep stage at a switch level is extracted to match flows of the GTP control plane packet and the GTP user plane packet and a correlation may be assigned to forward the GTP control plane packet and the GTP user plane packet to the same egress port.
