Network device and network packet processing method

A network device, comprising:

• a processor, arranged to generate a first predetermined packet, and provide the first predetermined packet to a core circuit;
• the core circuit, comprising:
• a packet parser, arranged to parse the first predetermined packet to obtain a first parsing result, generate a control information corresponding to the first predetermined packet according to the first parsing result, and provide the first predetermined packet and the control information to a front-end processing circuit;
• and
• the front-end processing circuit, comprising:
• a transmitting signal processing circuit, arranged to obtain a transmitting timestamp corresponding to the first predetermined packet in response to reception of the first predetermined packet, determine to write the transmitting timestamp into the first predetermined packet or a register according to the control information, and transmit the first predetermined packet.

A network packet processing method, applied to a network device, comprising:

• by a processor of the network device, generating a first predetermined packet, and providing the first predetermined packet to a core circuit of the network device;
• by a packet parser of the core circuit, parsing the first predetermined packet to obtain a first parsing result corresponding to the first predetermined packet, generating a control information corresponding to the first predetermined packet according to the first parsing result, and providing the first predetermined packet and the control information to a front-end processing circuit;
• and
• by the front-end processing circuit, obtaining a first transmitting timestamp corresponding to the first predetermined packet in response to reception of the first predetermined packet, determining to write the first transmitting timestamp into the first predetermined packet or a register according to the control information, and transmitting the first predetermined packet.
