[0045] In an exemplary embodiment, the method further comprises: acquiring configuration information of the preamble in the target message and configuring information, so that the front guideline of the target message supports the two or more or more. Code sequence.
[0046] That is, in order to better enable the preamble in the target message to be transmitted, after confirming the target message required to transmit, the configuration information of the target message is acquired, according to the two or more types of pattern sequences to be transmitted. The preamble pattern sequence is re-constructed on the configuration information of the target message, so that the preamble of the reconstructed target message supports the transmission of two or more types of code sequences.
[0047] In an exemplary embodiment, the configuration information of the preamble in the target message is acquired and the configuration of the configuration information is obtained, so that the preamble of the target message supports the two or more types of code type sequences. The above method also includes setting the preamble regularly in the target message, wherein the transmitting rule is configured to indicate a sequence of transmission sequences of the first code sequence and a second code sequence, and The transmitting rule includes at least one of the first code sequences of the first target length and the second target length of the second target length; the first code sequence of the third target length is continuously transmitted, and the first sequence of continuously sent After the one-yard sequence is sent, the second pattern sequence of the fourth target length is transmitted; the second type sequence of the fifth target length is continuously transmitted, and the sixth target length is transmitted after the continuous transmission of the second code sequence.

[0048] Briefly, in order to ensure that the re-construct in the target message can be sent in order, it is also possible to set the transmission rule of the construction of the preamble after the target message, so that the two or two types contained in the re-constructed preamble. The first code sequence of two or more type sequences is alternately transmitted by the second code type sequence, thereby improving transmission efficiency.
[0049] In an exemplary embodiment, the configuration information of the preamble in the target message is acquired, and the configuration of the configuration information is obtained, so that the preamble of the target message supports the two or more types of pattern sequences. Including: In the first target byte of the first code sequence into the target message, the first target byte is used to set at least one of the following: front guiding length, front guide repetition count The leading mode; the target queue of the second pattern sequence is added to the second target byte in the target message, wherein the second target byte is a blank to be filled with byte.

[0051] For example, when the target message is the Burst Proflie PLOAM message, the relevant field of the BURST Proflie PLOAM message is defined by the existing standard, and the length of the first size sequence can be represented by the 16th byte of the standard definition. Section represents the number of repetitions of the first size sequence, the first code type of the first size sequence in the preamble is indicated; the 34th byte represents the length of the second code sequence, the 35th byte is represented The number of repetitions of the biphotographic sequence, the 36-40 bytes represent the code type of the second pattern sequence; or the code type of the second pattern sequence can also be used, and the 40-byte representation The number of repetitions transmitted by a single-yard sequence and the second code sequence.

When the fifth bit (BINARY DITI, the BIT) is 0, the BURST Proflie PLOAM message does not support a multi-type pattern preamble. When the fifth bit is 1, the Burst Proflie PLOAM message supports a variety of code. Type preamble.
[0056] Figure 4 It is a flow diagram of the receiving method of the preamble according to an embodiment of the present invention, such as Figure 4 As shown, the process includes the following steps:
[0057] Step S302 receives a preamble comprising two or more types of code sequences, wherein the two or more types of code sequences include: a first code sequence and a second code sequence.
[0058] Optionally, the first code sequence is used for clock recovery, the second code type sequence for equalizer training convergence.
[0059] With the present invention, a preamble comprising two or more or more type sequences is received, wherein the two or more types of code type sequences include: a first pattern sequence and a second pattern sequence, wherein The first code sequence is used for clock recovery, and the second code type sequence is used for equalizer training convergence, that is, by supporting the preamble to support different pattern sequences, the functionality of different pattern sequences can be implemented to the preamble.
