a GFP mapping unit, configured to map the service signal to an intermediate layer GFP when the service signal needs to enter the intermediate layer GFP;
a GMP mapping unit, configured to map the service signal to an intermediate layer GMP when the intermediate layer GMP needs to enter;
an optical path data unit ODUk mapping unit, configured to directly map the service signal into an ODUk frame signal when GFP or GMP does not need to be entered.
10. The apparatus of claim 9,
the mapping processing module further comprises:
a second determining unit, configured to determine whether the service signal needs to enter an ODU0_ TS layer or an ODU1_ TS layer;
an ODU0_ TS mapping unit, configured to map the service signal to an ODU0_ TS layer when the service signal needs to enter an ODU0_ TS layer;
an ODU1_ TS mapping unit, configured to map the service signal to an ODU1_ TS layer when the service signal needs to enter an ODU1_ TS layer;
an ODUa mapping unit, configured to map the service signal from the ODUk mapping unit into a unified ODUa frame signal;
the ODUk mapping unit is further configured to map the service signal from the GFP mapping unit, the GMP mapping unit, the ODU0_ TS mapping unit, or the ODU1_ TS mapping unit into an ODUk frame signal.
11. The apparatus of claim 10, wherein the mapping processing module further comprises:
an optical transport network OTN framing unit, configured to pack the unified ODUa frame signal into a high-order OTN frame signal;
and the sending unit is used for sending the OTN frame signals packed by the OTN framing unit to a cross board.
