Abstract
An optical network unit (ONU) receives an Ethernet packet sent by user device and slices the Ethernet packet based on information about a minimum transmission unit to generate a first Ethernet packet slice, where a length of the minimum transmission unit is an integer multiple of a length of the first Ethernet packet slice. The ONU encapsulates the Ethernet packet slice and a slice identifier into a GEM frame, wherein the slice identifier indicates that the length of the minimum transmission unit of the OTN is an integer multiple of the length of the Ethernet packet slice. The Ethernet packet slice does not need to be processed by a network processor or a traffic management module in transmission of the OLT, thereby reducing a delay of network transmission.

A packet processing method, comprising:
- receiving, by an optical network unit (ONU), an Ethernet packet frame sent by a user device;
- slicing, by the ONU, the Ethernet packet frame based on information about a minimum transmission unit of an optical transport network (OTN) to generate a first Ethernet packet slice, wherein a length of the minimum transmission unit of the OTN is an integer multiple of a length of the first Ethernet packet slice;
- and
- sending, by the ONU, a GPON Encapsulation Mode (GEM) frame to an optical line terminal (OLT), wherein the Ethernet packet slice and a slice identifier are encapsulated into the GEM frame, and the slice identifier indicates that the length of the minimum transmission unit of the OTN is an integer multiple of the length of the Ethernet packet slice.
