Abstract

A method for sending a code block data stream includes adding m first data frames carrying the code block data stream to n physical layer data frames on an Ethernet physical interface. The method includes identifying a location of the first code block of each first data frame in the m first data frames using an alignment marker of a physical layer data frame in the n physical layer data frames. The method includes sending the n physical layer data frames, where m and n are integers greater than or equal to 1.

First claim

What is claimed is:

1 . A method for sending a code block data stream, wherein the method comprises:
adding, by a transmit end, m first data frames carrying the code block data stream to n physical layer data frames on an Ethernet physical interface; identifying, by the transmit end, a location of a first code block of each first data frame in the m first data frames using one alignment marker (AM) of one physical layer data frame in the n physical layer data frames; and sending, by the transmit end, the n physical layer data frames that carry the m first data frames of the code block data stream, wherein m and n are integers greater than or equal to 1.

2 . The method according to claim 1 , wherein the location of the first code block of each first data frame in the m first data frames one-to-one corresponds to one AM of one physical layer data frame in the n physical layer data frames.

3 . The method according to claim 1 , wherein locations of the first code blocks of at least two first data frames in the m first data frames correspond to one AM of one physical layer data frame in the n physical layer data frames.

4 . The method according to claim 1 , wherein the first code block in the code block data stream is a 64B/66B code block.

5 . A method for receiving a code block data stream, wherein the method comprises:
obtaining, by a receive end, n physical layer data frames that are on an Ethernet physical interface and that carry m first data frames of the code block data stream; determining, by the receive end, a location of the first code block of each first data frame in the m first data frames according to one alignment marker (AM) of one physical layer data frame in the n physical layer data frames; and performing, by the receive end, data restoration on the code block data stream using the first code block of each first data frame in the m first data frames as a start code block, wherein m and n are integers greater than or equal to 1.

6 . The method according to claim 5 , wherein the location of the first code block of each first data frame in the m first data frames one-to-one corresponds to one AM of one physical layer data frame in the n physical layer data frames.

7 . The method according to claim 5 , wherein locations of the first code blocks of at least two first data frames in the m first data frames correspond to one AM of one physical layer data frame in the n physical layer data frames.

8 . The method according to claim 5 , wherein the first code block in the code block data stream is a 64B/66B code block.

9 . A sending device for a code block data stream, wherein the sending device comprises:
a memory storing code; a processor coupled to the memory and configured to execute the code to:
add m first data frames carrying the code block data stream to n physical layer data frames on an Ethernet physical interface; and
identify a location of the first code block of each first data frame in the m first data frames by using one alignment marker (AM) of one physical layer data frame in the n physical layer data frames; and
a communications interface coupled to the processor and configured to send the n physical layer data frames that carry the m first data frames of the code block data stream, wherein m and n are integers greater than or equal to 1.

10 . The sending device according to claim 9 , wherein the location of the first code block of each first data frame in the m first data frames one-to-one corresponds to one AM of one physical layer data frame in the n physical layer data frames.

11 . The sending device according to claim 9 , wherein locations of the first code blocks of at least two first data frames in the m first data frames correspond to one AM of one physical layer data frame in the n physical layer data frames.

12 . The sending device according to claim 9 , wherein the first code block in the code block data stream is a 64B/66B code block.

13 . A receiving device for a code block data stream, wherein the receiving device comprises:
a memory storing code; and a processor coupled to the memory and configured to execute the code to:
obtain n physical layer data frames that are on an Ethernet physical interface and that carry m first data frames of the code block data stream;
determine a location of the first code block of each first data frame in the m first data frames according to one alignment marker (AM) of one physical layer data frame in the n physical layer data frames; and
perform data restoration on the code block data stream using the first code block of each first data frame in the m first data frames as a start code block, wherein m and n are integers greater than or equal to 1.

14 . The receiving device according to claim 13 , wherein the location of the first code block of each first data frame in the m first data frames one-to-one corresponds to one AM of one physical layer data frame in the n physical layer data frames.

15 . The receiving device according to claim 13 , wherein locations of the first code blocks of at least two first data frames in the m first data frames correspond to one AM of one physical layer data frame in the n physical layer data frames.

16 . The receiving device according to claim 13 , wherein the first code block in the code block data stream is a 64B/66B code block.
