Abstract

A transmission device includes: a payload generator configured to generate a payload; and an adding unit configured to add payload information on the payload to the payload, wherein the payload to which the payload information is added is transmitted via a first lane, and management information on the first lane is transmitted via a second lane.

First claim

What is claimed is:

1. A transmission device comprising:
a payload processor obtaining a payload from a frame generated from a data signal, the frame transmitted via a first lane and a second lane;
a separation processor configured to separate control information capable of being obtained from the frame into a first group including payload information on the payload and a second group including management information on the first lane; and
an adding unit configured to add the control information of the first group to the payload, wherein
the payload to which the control information of the first group is added is transmitted via the first lane, and the control information of the second group is transmitted via the second lane.

2. The transmission device according to claim 1 , further comprising:
an error correction code generator configured to generate an error correction code for correcting an error of the payload transmitted via the first lane and an error of the management information transmitted via the second lane, wherein
the error correction code is transmitted via a third lane.

3. The transmission device according to claim 2 , wherein
the error correction code is transmitted at a transmission rate less than a transmission rate of-the payload to which the control information of the first group is added.

4. The transmission device according to claim 1 , further comprising:
a frame generator configured to generate the frame from the data signal, wherein
the payload information and the management information are obtained from the frame.

5. The transmission device according to claim 1 , wherein
the payload information includes an identifier for identifying the payload generated from the data signal.

6. The transmission device according to claim 1 , wherein
the control information of the second group is transmitted at a transmission rate less than a transmission rate of the payload to which the control information of the first group is added.

7. A transmission system comprising:
a first transmission device that obtains a payload from a frame transmitted via a first lane and a second lane, separates control information capable of being obtained from the frame into a first group including payload information on the payload and a second group including management information on the first lane, and adds the control information of the first group to the payload, the frame generated from a data signal; and
a second transmission device coupled to the first transmission device, wherein
the first transmission device transmits the payload to which the control information of the first group is added via the first lane, and transmits the control information of the second group via the second lane, and
the second transmission device receives a signal transmitted via the first lane and a signal transmitted via the second lane.

8. A transmission method comprising:
obtaining a payload from a frame generated from a data signal, the frame transmitted via a first lane and a second lane;
separating control information capable of being obtained from the frame into a first group including payload information on the payload and a second group including management information on the first lane,
adding the control information of the first group to the payload;
transmitting the payload to which the control information of the first group is added via the first lane; and
transmitting the control information of the second group via the second lane.

9. The transmission method according to claim 8 , further comprising:
transmitting an error correction code via a third lane, the error correction code being used to correct an error of the payload transmitted via the first lane and an error of the management information transmitted via the second lane.

10. The transmission method according to claim 9 , wherein
the transmitting of the error correction code includes transmitting the error correction code at a transmission rate less than a transmission rate of the payload to which the control information of the first group is added.

11. The transmission method according to claim 8 , further comprising:
obtaining the payload information and the management information from a frame generated from a data signal.

12. The transmission method according to claim 8 , wherein
the payload information includes an identifier used to identify the payload generated from the data signal.

13. The transmission method according to claim 8 , wherein
the transmitting of the control information of the second group includes transmitting the control information of the second group at a transmission rate less than a transmission rate of the payload to which the control information of the first group is added.
