All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 2, the wavelength adaptive tuning method for a wavelength division network element provided in this embodiment includes:

In this embodiment, the wavelength configuration of each transmitting-end board of the transmitting-end network element (that is, a line-side board on the transmitting-end network element, where one line-side unit corresponds to one service access unit) may be completed in a manual configuration manner. For example, an operator may send a wavelength configuration file including target wavelength information to a sending-end single board on a sending-end network element through a network element management system in which the sending-end network element is located; after receiving the target wavelength information, the network element management system may only issue the target wavelength information to the corresponding receiving-end board on the sending-end network element, or may obtain the target address information of the receiving-end board corresponding to the sending-end board according to a corresponding relationship between each sending-end board of the sending-end network element and each receiving-end board of the receiving-end network element (the corresponding relationship may be stored on the network element management system in the network), and then add the target address information and the target wavelength information to a wavelength configuration file to send to the sending-end board corresponding to the sending-end network element, where of course, the configuration file also includes address information of the sending-end board to be configured.
In this embodiment, the network element management system specifically sends the wavelength configuration file to the control board of the sending-end network element, and after receiving the wavelength configuration file, the control board finds the corresponding sending-end single board according to the address information of the sending-end single board to be configured in the configuration file, and sends the target wavelength information to the sending-end single board for configuration. Of course, the target address information may also be issued to the sending-end single board.
The wavelength tuning devices in S201 and S202 may specifically obtain the target wavelength information and the target address information from a configuration file on the sending-end board, or may directly obtain the configuration file of the sending-end board from the network element management system, so as to obtain the target wavelength information and the target address information. Or directly obtaining target wavelength information issued by an operator from the network element management system, and then obtaining target address information of the receiving end single plate corresponding to the sending end single plate according to the corresponding relation between each sending end single plate of the sending end network element and each receiving end single plate of the receiving end network element on the network element management system. It should be understood that there is no strict timing limitation between S201 and S202 in the embodiment, and both may be performed simultaneously or in tandem.
The wavelength tuning device in S203 may adopt various methods that can implement sending the obtained target address information and target wavelength information to a receiving-end single board corresponding to a receiving-end network element to complete wavelength information configuration. For example, the present embodiment may employ, but is not limited to, at least one of the following three methods:
directly using the network element management system to perform comprehensive and uniform management characteristics on each network element below the network element management system, and sending the target address information and the target wavelength information to the corresponding receiving end single board on the receiving end network element.
Utilizing reserved overhead bytes in a subcarrier signal frame structure in an optical signal to write target address information and target wavelength information into the overhead bytes and send the overhead bytes to a receiving terminal network element along with a main carrier signal; after receiving the signal, the receiving end network element performs wave division and analysis to extract corresponding target address information and target wavelength information from the subcarrier signal, and completes wavelength setting on a corresponding receiving end single board.
And modulating the target address information and the target wavelength information to the power of an optical signal sent by the sending terminal network element to the receiving terminal network element by using wavelength power coding, and demodulating the corresponding target address information and the corresponding target wavelength information from the received optical signal by the receiving terminal network element through corresponding power decoding to complete wavelength setting on the corresponding receiving terminal single board.
According to the method, the setting of the wavelength information of the single board of the corresponding receiving end can be automatically realized according to the setting of the wavelength information of the single board of the transmitting end, so that the wavelength information of the single board of the corresponding receiving end is kept consistent, the wavelength of the single board of the receiving end does not need to be additionally set manually by an operator, the self-adaptability is good, and the setting accuracy is high. In order to better understand the solution of the embodiments of the present invention, the following further examples are given in conjunction with several specific embodiments.
Example two:
in this embodiment, a wavelength tuning device is taken as an example of a network element management system for managing the sending-end network element and the receiving-end network element, which is shown in fig. 3.
At this time, the step of acquiring the target wavelength configuration information and the target address information by the wavelength tuning apparatus (that is, the network element management system) includes:
the target wavelength information is obtained according to the wavelength configuration instruction issued by the user for the sending end single board, because the user issues the wavelength configuration instruction to specify the configured target wavelength information through the network element management system when performing the wavelength configuration for the sending end single board, the target wavelength information can be directly obtained from the wavelength configuration instruction issued by the user to the network element management system, and the instruction also includes the address information of the sending end single board to be configured. The address information of the board in this embodiment may also be unique identification information of the board, and the unique identification information may be composed of a slot number and a sub-frame number where the board is located. After the address information of the sending-end single board to be configured is obtained, the target address information of the receiving-end single board corresponding to the sending-end single board to be configured may be obtained according to the corresponding relationship between each sending-end single board of the sending-end network element and each receiving-end single board of the receiving-end network element.
After acquiring the target address information and the target wavelength information, the network element management system configures the wavelength information of the receiving end single board corresponding to the target address information into the target wavelength information, and the configuring includes:
the network element management system sends the target address information and the target wavelength information to a control panel of a receiving terminal network element; the control board can find the corresponding receiving single board according to the target address information and send the target wavelength information to the receiving end single board, so that the receiving end single board configures the wavelength information into the target wavelength information.
For example, as shown in fig. 3, an opposite end of a sending-end single board 1 of a sending-end network element is a receiving-end single board 1 in a receiving-end network element, when an operator performs wavelength tuning adjustment on the sending-end single board 1 on a network element management system, and sets the wavelength of the sending-end single board 1 to λ 1, the network element management system identifies and confirms that the opposite end of the sending-end single board 1 is the receiving-end single board 1 according to the above method, and then automatically issues a wavelength tuning adjustment command containing target wavelength information λ 1 to the receiving-end single board, and sets the wavelength of the receiving-end single board to λ 1, thereby.
Example three:
in this embodiment, a reserved overhead byte in a sub-carrier signal frame structure in an optical signal is used, and target address information and target wavelength information are written into the overhead byte and sent to a receiving-end network element along with a main carrier signal, so as to exemplify a setting of a wavelength completed by a receiving-end single board.
At this time, the wavelength tuning device acquiring the target wavelength configuration information and the target address information includes: and acquiring target wavelength information and target address information from the wavelength configuration file of the transmitting end single board. The wavelength configuration file in this embodiment may be directly obtained from the sending-end single board and/or the control single board of the network element, or may be directly obtained from the network element management system.
After obtaining the target wavelength information and the target address information, the wavelength tuning device configures the wavelength information of the receiving end single plate corresponding to the target address information into the target wavelength information, including:
writing the target wavelength information and the target address information into the subcarrier of the sending end single plate, and sending the subcarrier to a receiving end network element along with the main carrier of the sending end single plate;
after a receiving terminal network element receives an optical signal from a sending terminal network element, performing optical splitting processing on the optical signal to obtain a main carrier signal and a sub-carrier signal, extracting target wavelength information and target address information from the obtained sub-carrier before the sending terminal network element sends the obtained main carrier signal to a receiving terminal single board corresponding to the target address information, and sending the target wavelength information and the target address information to a control board of the receiving terminal network element; after receiving the target address information, the control board can find the corresponding receiving end single board according to the target address information, and sends the target wavelength information to the receiving end single board so as to set the wavelength of the target wavelength information to be the same as that of the corresponding transmitting end single board.
Specifically, the writing of the target wavelength information and the target address information into the subcarrier of the sending-end board in this embodiment includes: and coding the target wavelength information and the target address information and writing the coded target wavelength information and the coded target address information into overhead bytes of a subcarrier signal frame. And the encoding in this embodiment may adopt binary encoding, octal encoding or hexadecimal encoding, etc. In the embodiment, the information is transmitted by using the spare overhead bytes in the frame structure, so that the change is small, the cost is low, and the control is flexible. After the receiving end network element receives the optical signal and separates out the subcarrier optical signal, the target wavelength information and the target address information can be read from the overhead byte in the frame structure.
Specifically, the wavelength tuning apparatus in this embodiment may extract the target wavelength information and the target address information from the sub-carriers and send the target wavelength information and the target address information to the control board of the receiving-end network element after the receiving-end network element receives the optical signal from the sending-end network element and performs the wavelength division processing to obtain the main carrier and the sub-carriers. Referring to fig. 4, after receiving an optical signal sent by a sending-end network element, a wavelength multiplexing/demultiplexing unit in a receiving-end network element performs wavelength division processing to obtain a service signal (i.e., a main carrier signal) and an OSC (optical supervisory Channel) signal (i.e., a subcarrier signal, which is mainly used for transmitting various management information) respectively; and before the receiving network element issues the obtained service information to the receiving end single board, extracting corresponding target wavelength information and target address information from overhead bytes of a subcarrier signal frame structure, and issuing the target wavelength information and the target address information to the receiving end single board corresponding to the target address information through a control board to complete wavelength information setting. Thus, the receiving end single board can successfully frame and receive signals. For example: at present, the most common wavelength division of the DWDM system is an 80-wavelength division system, and assuming that binary coding is adopted for the 80-wavelength division, 7 bits can complete the coding of 128-wavelength division, thereby meeting the requirements and being completely written into the overhead of a subcarrier signal frame structure.
The wavelength tuning device in this embodiment may be implemented by directly using corresponding software and hardware (e.g., programmable logic devices) on the sending-end single board and the receiving-end single board, or may be completely independent of the sending-end single board and the receiving-end single board.
As shown in fig. 5, the opposite end of the sending-end single board 2 of the sending-end network element is a receiving-end single board in the receiving-end network element, when an operator adjusts and tunes the wavelength of the sending-end single board 2, and sets the wavelength to λ 2, at this time, the sending-end single board 2 uses a proprietary wavelength coding protocol (such as binary coding) to change λ 2 into 7-bit binary information, the binary information is written into overhead reserved bytes in a subcarrier signal frame structure through single board software and a programmable logic device, the information is transmitted to the receiving-end network element along with a main carrier signal (i.e. a service signal), the receiving-end network element obtains a subcarrier signal according to the above processing and sends the subcarrier signal to the receiving-end single board 2, the receiving-end single board 2 adopts a corresponding decoding protocol to identify and analyze corresponding bytes, and extract target wavelength information λ 2, and then automatically sets, thereby keeping the wavelength of the single plates at both ends of the line side consistent.
Example four:
in this embodiment, the wavelength power coding is used to modulate the target address information and the target wavelength information onto the power of the optical signal sent by the sending-end network element to the receiving-end network element, and the receiving-end network element demodulates the corresponding target address information and the corresponding target wavelength information from the received optical signal through the corresponding power decoding to complete the wavelength setting for the corresponding receiving-end single board.
At this time, the wavelength tuning device acquiring the target wavelength configuration information and the target address information includes: and acquiring target wavelength information and target address information from the wavelength configuration file of the transmitting end single board. The wavelength configuration file in this embodiment may be directly obtained from the sending-end single board and/or the control single board of the network element, or may be directly obtained from the network element management system.
After obtaining the target wavelength information and the target address information, the wavelength tuning device configures the wavelength information of the receiving end single plate corresponding to the target address information into the target wavelength information, including:
before the sending terminal network element sends the generated optical signal to the receiving terminal network element, the target wavelength information and the target address information are modulated to the power of the optical signal according to a preset power coding protocol; specifically, the wavelength tuning device modulates the target wavelength information and the target address information onto the power of the main carrier signal of the optical signal. Of course, the target wavelength information and the target address information may be modulated on the power of the subcarrier signal of the optical signal according to actual requirements.
It should be understood that the optical power encoding protocol in this embodiment can be flexibly set according to the optical signal power in a specific application scenario, as long as the target wavelength information and the target address information can be reliably modulated onto the power of the optical signal. The receiving end network element only needs to be able to analyze the target wavelength information and the target address information from the optical signal by using a corresponding preset power decoding protocol.
When the receiving end network element receives the optical signal, target wavelength information and target address information are analyzed from the optical signal according to a preset power decoding protocol and are sent to a control board of the receiving end network element so as to configure the wavelength information of the receiving end single board into the target wavelength information. The analyzed optical signal can still be processed by the optical line processing unit and the wavelength multiplexing/demultiplexing unit according to the original processing flow and sent to the corresponding receiving end single board for processing.
Specifically, the wavelength tuning apparatus in this embodiment may include a power encoding unit and a power decoding unit respectively disposed at the sending-end network element side and the receiving-end network element side, and for the power encoding unit, the wavelength configuration file may be directly obtained from the network element management system, and then the target wavelength information and the target address information extracted therefrom are modulated onto the power of the main carrier signal by controlling the optical power; the power decoding unit at the receiving end network element side analyzes the different power values of the received optical signals into wavelength information and receiving end address information, and then sends the wavelength information and the receiving end address information to the control board to carry out corresponding setting on the wavelength information of the corresponding receiving end single board. As described above, this method needs to make a proprietary optical power encoding protocol, that is, different optical power value combinations represent different information, so that the target wavelength information and the target address information can be transmitted by modulating the optical power loaded on the optical signal.
As shown in fig. 6, an optical signal of a sending-end network element passes through a power encoding unit, and target wavelength information and target address information of a sending-end single board are modulated on optical power of the optical signal according to a private optical power encoding protocol by using an optical power encoding method, and transmitted to a receiving-end network element.

in this embodiment, the wavelength configuration of each transmitting-end board of the transmitting-end network element (that is, a line-side board on the transmitting-end network element, where one line-side unit corresponds to one service access unit) may be completed in a manual configuration manner. For example, an operator may send a wavelength configuration file including target wavelength information to a sending-end single board on a sending-end network element through a network element management system in which the sending-end network element is located; after receiving the target wavelength information, the network element management system may only issue the target wavelength information to the corresponding receiving-end board on the sending-end network element, or may obtain the target address information of the receiving-end board corresponding to the sending-end board according to the corresponding relationship between each sending-end board of the sending-end network element and each receiving-end board of the receiving-end network element, then add the target address information and the target wavelength information to the wavelength configuration file and send the wavelength configuration file to the sending-end board corresponding to the sending-end network element, where of course, the configuration file also includes the address information of the sending-end board to be configured.
In this embodiment, the network element management system specifically sends the wavelength configuration file to the control board of the sending-end network element, and after receiving the wavelength configuration file, the control board finds the corresponding sending-end single board according to the address information of the sending-end single board to be configured in the configuration file, and sends the target wavelength information to the sending-end single board for configuration. Of course, the target address information may also be issued to the sending-end single board.
The information processing module 71 may specifically obtain the target wavelength information and the target address information from a configuration file on the sending-end board, or may directly obtain the configuration file of the sending-end board from the network element management system, so as to obtain the target wavelength information and the target address information.

In this embodiment, the setting of the wavelength information of the corresponding receiving end single plate can be automatically realized according to the setting of the wavelength information of the transmitting end single plate, so that the wavelength information of the transmitting end single plate and the wavelength information of the receiving end single plate are consistent. Compared with the prior art, the method has the advantages that the effect of self-adapting the opposite-end wavelength is achieved, the steps of manually configuring the wavelengths at the two ends are reduced, and the troubles of service blockage and the like caused by subjective negligence are avoided.
