Abstract: The present invention discloses an apparatus and a method for transporting an ODU service. The transport apparatus includes a first ODU service processing unit, a timeslot allocation unit, a switching output port allocation unit, an Ethernet switching unit, and a second ODU service processing unit, where a table of a mapping between output ports of the first ODU service processing unit and timeslots is determined according to a rate of an ODUflex frame carried in an obtained ODU service and the number of the output ports of the first ODU service processing unit, and the ODU service is forwarded, which resolves a problem in the prior art that an ODUflex frame cannot be transported by using the Ethernet switching unit, thereby ensuring that service congestion does not occur on a forwarding port of a sending apparatus, and improving transmission quality of a communications network.
