Forwarding table generation method and forwarding device

A data forwarding device, comprising:

• a receiver configured to receive, via multiple second timeslots of at least one receiving PHY of a forwarding device, multiple encoded data blocks of a flexible Ethernet (FlexE) client sent by an upstream second device;
• and
• a processor coupled to the receiver, configured to:
• forwarding, via multiple first timeslots of at least one sending PHY of the forwarding device, the received multiple encoded data blocks to a downstream first device;
• and
• avoiding performing layer 2 and layer 3 processing on the FlexE client in a process from receiving the multiple encoded data blocks to forwarding the multiple encoded data blocks.
