Patent ID: 8305925

Claim:
A method for transporting a multi-lane Ethernet signal, comprising: configuring a number of timeslot channels in an Optical channel Payload Unit-k virtual concatenation frame (OPUk-Xv) based on number of lanes of the multi-lane Ethernet signal; assigning each timeslot channel to a corresponding lane of Ethernet data in the multi-lane Ethernet signal; mapping each lane of the Ethernet data in the multi-lane Ethernet signal into each corresponding timeslot channel; populating each of negative justification opportunity (NJO) bytes and positive justification opportunity (PJO) bytes of each timeslot channel with a content of justification information or Ethernet data according to a frequency difference between each lane of the Ethernet data in the multi-lane Ethernet signal and each corresponding timeslot channel; and indicating, in justification control (JC) bytes, whether the content populated in each of the NJO bytes and the PJO bytes is the justification information or the Ethernet data; splitting the OPUk-Xv carrying the multi-lane Ethernet signal into a plurality of Optical channel Transport Unit-k (OTUk) frames for transmission.
