Abstract
A method of transmitting data in an optical transport network is provided. The method comprises generating an optical transmission unit frame including an in-band area including a first area to which information data is allocated and a second area to which the information data is not allocated and an out-band area including parity information and transmitting the data through the optical transmission unit frame.
Claims20
A method for receiving client signal in an optical transport network, comprising:
- receiving an optical transmission unit (OTU) frame including an in-band area and an out-band area,
- wherein the in-band area includes a first area to which the client signal is allocated and a second area to which fixed stuff is allocated;
- and
- demapping the client signal from the first area.
The method of claim 7, further comprising:
- performing an error correction of the information data by using the information included in the out-band area.
A method for receiving tributary signal in an optical transport network, comprising:
- receiving an optical transmission unit (OTU) frame including an in-band area and an out-band area,
- wherein the in-band area includes a first area to which the tributary signal is allocated and a second area to which fixed stuff is allocated;
- and
- demapping the tributary signal from a plurality of tributary slots included in the first area.
An apparatus of receiving data signal in an optical transport network, comprising:
- a receiver configured to receive an optical transmission unit (OUT) frame including an in-band area and an out-band area, wherein the in-band area includes a first area to which the data signal is allocated and a second area to which fixed stuff is allocated;
- and
- demapper configured to demap the client signal from the first area.
