[0030] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the control method of a control unit, an electronic device, and a computer-readable medium provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0031] In the following, example embodiments will be described more fully with reference to the accompanying drawings, but the example embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0032] In the case of no conflict, the various embodiments of the present disclosure and the various features in the embodiments may be combined with each other.

[0033] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. As used herein, the singular forms "a" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that when the present specification uses the terms "comprises" and / or "consists of", it specifies the presence of the stated features, wholes, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their groups.

[0035] Unless otherwise defined, all terms (including technical and scientific terms) used herein shall have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries shall be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and shall not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0036] In the present disclosure, unless otherwise specified, the following technical terms shall be understood according to the following explanations:

[0037] An OTN device refers to an optical transmission network device including at least one of sub-wavelength OCH (Optical Channel) such as ODUk (Optical channel Data Unit k), ODUflex (Optical channel Data Unit Flex with flexible capacity), and units with wavelength-level switching capabilities.

[0038] Among them, the optical layer in the OTN device can be used for processing such as modulation and demodulation of optical signals, and the electrical layer can be used to achieve the conversion of optical and electrical signals.

[0039] An IP device is a device with IP communication functions, such as a router, a switch, etc., which can be connected to an OTN device and interact with the OTN device through optical signals.

[0040] Figure 1 It is a schematic diagram of an application scenario of a related technology. Refer to Figure 1 , in a related technology, service signals are transmitted between the electrical layers of an IP device and an OTN device in a way of gray-light interconnection. Among them, the IP device and the OTN device respectively manage and set service information related to the interconnection port through their respective network management modules. The electrical layer of the OTN device reprocesses the gray-light signals transmitted by the IP device and generates colored-light signals through FEC (Forward Error Correction) in the electrical layer. The colored-light signals then pass through the multiplexer / demultiplexer and OA (Optical Amplifier) in the optical layer in sequence and enter the optical fiber for transmission to improve the transmission distance and single-fiber transmission bandwidth. Among them, information such as the transmission code pattern, FEC, wavelength, optical power, and spectral width of the colored-light optical module required to generate the colored-light signals can be directly obtained and set from the electrical layer. However, since this way of transmitting service signals needs to pass through the electrical layer of the OTN device and an FEC needs to be added in the electrical layer of the OTN device, the network construction cost is relatively high.

[0041] In another related technology, the IP device directly loads a color optical module, and the service signal is transmitted between the optical layers of the IP device and the OTN device in a color optical interconnection manner. Although it can save the electrical layer of the OTN device and reduce the network construction cost, the IP device and the OTN device cannot be coordinated. Although the service signal can be transmitted, information such as the transmission code pattern, FEC, wavelength, optical power, and spectral width of the color optical module required by the OTN device cannot be coordinated for acquisition and setting.

[0042] Therefore, there is an urgent need to provide a solution that can not only achieve coordination between the IP device and the OTN device at low cost but also reduce the implementation difficulty. The embodiments of the present disclosure can directly receive the OAM (Operation Administration and Maintenance) information of the IP device through the optical layer of the OTN device, and directly send control instructions to the IP device through the optical layer of the OTN device to achieve the coordination between the OTN device and the IP device.

[0043] Figure 2 It is a flowchart of an information transmission method for an IP device provided by an embodiment of the present disclosure. In a first aspect, referring to Figure 2 , an embodiment of the present disclosure provides an information transmission method for an IP device. The IP device includes a color optical module, and the method includes:

[0044] S11. Determine a first tone modulation signal according to the OAM information, where the first tone modulation signal carries the OAM information;

[0045] S12. Send the first tone modulation signal as an optical-in-band signal in a first color optical signal to an optical transport network (OTN) device.

[0046] In this embodiment, a color optical module is set in the IP device, and the first tone modulation signal carrying the OAM information is sent as an optical-in-band signal of the first color optical signal to the optical layer of the OTN device through the IP device. Without passing through the electrical layer of the OTN device and without adding a new upper-layer network management, the OAM information can be directly transmitted to the optical layer of the OTN device, realizing the coordination between the OTN device and the IP device and reducing the network construction cost.

[0047] In some embodiments, S11 includes: performing modulation processing on the OAM information to obtain the first tone modulation signal.

[0048] In some embodiments, a coherent DSP (Digital Signal Processor) chip or a SiP VOA (Silicon Photonics Variable Optical Attenuator) / InP SOA (Indium Phosphide Semiconductor Optical Amplifier) optical chip is provided in the color light optical module. The IP device can modulate the OAM information through the coherent DSP chip or the SiP VOA / InP SOA optical chip to obtain a first pilot tone signal.

[0049] It should be noted that since the color light optical module of the IP device has no additional communication transmission channels for interacting with other information except for color light intercommunication with the OTN device, the first pilot tone signal carrying the OAM information is transmitted to the OTN device as an optical subcarrier signal of the first color light signal, that is, the first color light signal is subjected to pilot tone processing, and a low-speed optical subcarrier signal (the first pilot tone signal) is generated for the main signal (i.e., the first color light signal) of the wavelength channel at the transmitting end by using frequency modulation or amplitude modulation technology. The first pilot tone signal does not occupy the service channel of the first color light signal.

[0050] In some embodiments, the OAM information includes at least one of the following: transmission code pattern, forward error correction FEC, wavelength, optical power, and spectral width.

[0051] In the embodiments of the present disclosure, the OAM information is not fixed and can be adjusted according to actual situations.

[0052] In some embodiments, the color light optical module of the IP device includes a first optical layer OAM protocol proxy unit for reading the OAM information.

[0053] In some embodiments, the information transmission method further includes:

[0054] When the second pilot tone signal is detected, a control command is determined according to the second pilot tone signal. The second pilot tone signal carries the control command, and the second pilot tone signal is an optical subcarrier signal in the second color light signal.

[0055] In an embodiment of the present disclosure, since the color optical module of the IP device has no additional communication transmission channels for interacting with other information except for color optical interworking with the OTN device, when the OTN device sends a control command to the color optical module of the IP device, the second tone modulation signal carrying the control command is transmitted to the color optical module of the IP device as the optical accompanying signal of the second color optical signal. The second tone modulation signal does not occupy the service channel of the second color optical signal, realizing the remote control of the OTN device over the IP device. In some embodiments, the control command includes at least one of module configuration information, transmission performance alarm information, and module reset instruction.

[0056] In some embodiments, the IP device can demodulate the second tone modulation signal through a coherent DSP chip or a SiP VOA / InP SOA optical chip to obtain the control command. Correspondingly, the first optical layer OAM protocol proxy unit of the color optical module of the IP device can perform protocol conversion on the control instruction so that the IP network management can obtain the control instruction of the OTN device.

[0057] In some embodiments, the IP device detects the second tone modulation signal through an optoelectronic detection device. The embodiments of the present disclosure do not make special limitations on the optoelectronic detection device, which can be a sensor, a laser detector, etc.

[0058] In addition, since the IP device and the OTN device interact through color optical interworking, the second tone modulation signal detected by the IP device is an optical signal. The color optical module of the IP device further includes an optoelectronic conversion functional module for converting the detected optical signal (i.e., the second tone modulation signal) into an electrical signal.

[0059] In the embodiments of the present disclosure, the IP device sends the first tone modulation signal carrying OAM information to the optical layer of the OTN device as the optical accompanying signal of the first color optical signal, and the OTN device sends the second tone modulation signal carrying the control instruction to the color optical module of the IP device as the optical accompanying signal of the second color optical signal. The OAM information can be directly transmitted to the optical layer of the OTN device without passing through the electrical layer of the OTN device, and there is no need to additionally set up an upper-layer network management, which not only realizes the cooperation between the IP device and the OTN device but also reduces the network construction cost.

[0060] Figure 3 This is a flowchart of an information transmission method for an OTN device provided by an embodiment of the present disclosure. Second, referring to Figure 3 , an embodiment of the present disclosure provides an information transmission method for an OTN device. The method includes:

[0061] S21. When the first overhead signal is detected, determine OAM information according to the first overhead signal, where the first overhead signal carries the OAM information, and the first overhead signal is an optical supervisory channel signal in a first colored optical signal.

[0062] In some embodiments, determining the OAM information according to the first overhead signal in S21 includes: demodulating the first overhead signal to obtain the OAM information.

[0063] In the embodiments of the present disclosure, the optical layer of the OTN device can detect the first overhead signal through an optoelectronic detection device. Then, the detected first overhead signal is demodulated to obtain the OAM information transmitted with the first overhead signal. In some embodiments, the optical layer of the OTN device further includes a second optical layer OAM protocol proxy unit for protocol conversion of the OAM information. The second optical layer OAM protocol proxy unit converts the demodulated OAM information and uploads it to the OTN network management, so that the operation and maintenance personnel can obtain the OAM information by querying the OTN network management. Further, the wavelength ports, filtering bandwidth, gain, attenuation, etc. of the multiplexer / demultiplexer in the OTN optical layer can be set according to the OAM information.

[0064] The embodiments of the present disclosure do not make special limitations on the optoelectronic detection device, which can be a sensor, a laser detector, etc. It should be noted that the first overhead signal is transmitted from the IP device to the OTN device along with the first colored optical signal. When the OTN device detects the first overhead signal, it will not affect the transmission of the first colored optical signal and the first overhead signal. That is to say, the first overhead signal will continue to be transmitted in the OTN device along with the first colored optical signal.

[0065] In addition, since the IP device and the OTN device interact through the colored optical interconnection method, the first overhead signal detected by the OTN device is an optical signal. Correspondingly, the optical layer of the OTN device further includes an optoelectronic conversion function module for converting the detected optical signal (i.e., the first overhead signal) into an electrical signal.

[0066] In some embodiments, the information transmission method further includes:

[0067] Determine a second overhead signal according to a control command, where the second overhead signal carries the control command;

[0068] Send the second overhead signal as an optical supervisory channel signal in a second colored optical signal to the IP device.

[0069] In an embodiment of the present disclosure, the second topping signal carrying the control command is sent to the IP device as the optical line signal of the second colored optical signal through the optical layer of the OTN device, without passing through the electrical layer of the OTN device and without adding a new upper network management, and the control command can be directly transmitted to the optical layer of the IP device, realizing the cooperation between the OTN device and the IP device and reducing the network construction cost.

[0070] In some embodiments, the control instruction is obtained from the OTN network management above the OTN device. The OTN network management sends at least one of the module configuration information, transmission performance alarm information, and module reset instruction to the second optical layer OAM protocol proxy unit to obtain the control instruction.

[0071] In some embodiments, the second colored optical signal is a service signal or a basic optical signal transmitted by the OTN device to the IP device;

[0072] When the second colored optical signal is a basic optical signal, before sending the second topping signal as the optical line signal in the second colored optical signal to the IP device, it further includes:

[0073] Adjust the optical power of the DC optical signal through a variable optical attenuator to obtain a basic optical signal.

[0074] In an embodiment of the present disclosure, when the optical layer of the OTN device transmits the second topping signal to the IP device, an optical signal is required as a basis. Therefore, when the OTN device has a service signal transmitted to the IP device, the service signal is topped to enable the second topping signal to be sent to the IP device as the optical line signal of the service signal. When the OTN device has no service signal transmitted to the IP device, the OTN device can generate a basic optical signal to realize sending the second topping signal as the optical line signal in the basic optical signal to the IP device. Among them, the DC optical signal is obtained after the out-of-band DC optical signal is processed by a 1xN power splitter, and the present disclosure is not limited thereto.

[0075] The present disclosure does not make special limitations on the method of generating the basic optical signal. As an example, after the out-of-band DC optical signal is divided into multiple optical signals by a 1×N power splitter, the basic optical signal is obtained through the processing of a filter.

[0076] In some embodiments, the optical layer of the OTN device uses at least one of an eVOA (Electrically Variable Optical Attenuator) and an SOA (Semiconductor Optical Amplifier) to use the second topping signal as the optical line signal in the basic optical signal and perform topping processing on the basic optical signal.

[0077] In an embodiment of the present disclosure, the optical layer of the OTN device detects the optical overhead signal of the first colored optical signal (i.e., the first tone overhead signal carrying OAM information). At the same time, when the optical layer of the OTN device needs to send a control instruction to the IP device, the OTN device sends the second tone overhead signal carrying the control instruction as the optical overhead signal of the second colored optical signal to the colored optical module of the IP device, realizing the cooperation between the IP device and the OTN device. At the same time, the OAM information can be directly transmitted to the optical layer of the OTN device without passing through the electrical layer of the OTN device, and there is no need to additionally set up an upper-layer network management, reducing the network construction cost.

[0078] In a third aspect, referring to Figure 4 , an embodiment of the present disclosure provides an IP device, including:

[0079] A colored optical module, including: a laser unit and a first cooperation unit;

[0080] The laser unit includes a first transmission subunit;

When the at least one program is executed by the at least one first processing subunit 401, the first transmission subunit, and the first reception subunit, the at least one first processing subunit 401, the first transmission subunit, and the first reception subunit implement the information transmission method of any one of the above;

[0083] At least one first I / O interface 403, connected between the first processing subunit 401 and the first memory 401, is configured to implement the information interaction between the first processor 401 and the first memory 402.

[0085] In a fourth aspect, referring to Figure 5 , an embodiment of the present disclosure provides an OTN device, including:

[0086] The multiplexer / demultiplexer module includes: a color light detection unit and a second cooperation unit;

[0087] The color light detection unit includes a second receiving subunit;

[0089] Wherein, in the second memory 502, at least one program is stored thereon. When the at least one program is executed by the second receiving subunit, the at least one second processing subunit 501, and the second sending subunit, the second receiving subunit, the at least one second processing subunit 501, and the second sending subunit implement the information transmission method of any one of the above;

[0090] At least one second I / O interface 503 is connected between the second processing subunit 501 and the second memory 502, and is configured to implement information interaction between the second processing subunit 501 and the second memory 502.

[0092] Fifthly, referring to Figure 6 , an embodiment of the present disclosure provides a computer-readable medium, on which a computer program is stored. When the program is executed by a processor, the information transmission method of any one of the above is implemented.

[0093] In order to enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present disclosure, the technical solutions provided by the embodiments of the present disclosure will be described in detail below through specific embodiments:

[0094] Figure 7 It is a schematic structural diagram of an OTN device and an IP device provided by an embodiment of the present disclosure. Figure 8 It is a schematic structural diagram of a multiplexer / demultiplexer module in an OTN device and a color light optical module of an IP device provided by an embodiment of the present disclosure. Referring to Figure 7 andFigure 8 , as an example, the colored-light optical module of the IP device includes a first sub-component composed of a laser unit and a first cooperation unit. Among them, the laser unit includes a first transmission sub-unit (Tx), and the first cooperation unit includes a first reception sub-unit (Rx) and a first processing sub-unit. Through interaction with the OTN device, the first sub-component can send OAM information to the IP device, and can also implement the distribution of management and control information (such as control instructions) that needs to be executed to the colored-light optical module, and the upload of information that needs to be fed back (such as feedback information of control instructions) to the OTN device, so as to realize the remote management of the IP device through the OTN device.

[0095] The optical layer of the OTN device includes a second sub-component composed of a colored-light detection unit and a second cooperation unit. Among them, the colored-light detection unit includes a second reception sub-unit for optoelectronic detection, and the second cooperation unit includes a second processing sub-unit. The second sub-component can send the management and control information (such as control instructions) of the OTN device to the first sub-component of the IP device, and at the same time can receive the OAM information sent by the first sub-component of the IP device and feed it back to the OTN network manager.

[0096] Among them, the process of the colored-light optical module of the IP device and the optical layer of the OTN device for sending and receiving OAM information through the first sub-component and the second sub-component is as follows:

[0097] The first transmission sub-unit in the first sub-component loads the first tone signal onto the first colored-light signal through a coherent DSP chip or a SiP VOA / InP SOA optical chip. Among them, the first tone signal is obtained by modulating the OAM information, and the first tone signal carries the relevant identifier of the first fixed colored-light signal and the burst-reprogrammable OAM information.

[0098] The second reception sub-unit in the second sub-component performs optoelectronic detection. When the first tone signal is detected, the OAM information is demodulated from the first tone signal and fed back to the OTN network manager at the upper layer of the OTN device.

[0099] Among them, the process of the colored-light optical module of the IP device and the optical layer of the OTN device for sending and receiving control instructions through the first sub-component and the second sub-component is as follows:

[0100] The second cooperation unit in the second sub-component further includes a second transmission sub-unit. The second processing sub-unit top-loads a second top-loading signal on the second color optical signal through a fast VOA or SOA. The second top-loading signal serves as the optical sub-carrier signal of the second color optical signal and is sent by the second transmission sub-unit to the color optical module of the IP device. Among them, in the presence of a service signal, the service signal can be used as the second color optical signal with the second top-loading signal following it. In the absence of a service signal, an out-of-band DC optical signal of the OTN device can be used to generate a basic optical signal, and the basic optical signal can be used as the second color optical signal with the second top-loading signal following it to achieve signaling interaction. Among them, the basic optical signal is provided by the out-of-band DC optical signal through a 1xN power splitter.

[0101] The first cooperation unit in the first sub-component further includes a first receiving sub-unit (Rx). The first receiving sub-unit can perform photoelectric detection in the main optical path splitting before the ICR (Current-Feedback Optical Integrated Circuit). When the second top-loading signal is detected, a control instruction is demodulated from the second top-loading signal through a coherent DSP chip or a SiP VOA / InP SOA optical chip. After the control instruction is demodulated, the first processing sub-unit in the first sub-component can be used for the optical layer OAM protocol proxy, that is, execute the control instruction issued by the OTN device to achieve the interaction between the color optical module and the OTN device. Among them, the control instruction can be basic operations including configuration, query, and reset, or active operations including supporting module attributes, performance alarms, and closed-loop optimization.

[0102] It should be noted that by adding a sub-component (such as the first sub-component, the second sub-component) inside each of the multiplexer / demultiplexer modules of the color optical module and the OTN device, and loading top-loading signals (such as the first top-loading signal, the second top-loading signal) on the color optical signals (such as the first color optical signal, the second color optical signal) that communicate between the IP device and the OTN device, remote management of the color optical module on the IP device by the OTN device is achieved, and further cooperation between the IP and OTN devices is realized. All management and control can be executed through the OTN network management on the upper layer of the OTN device, effectively reducing the implementation difficulty of the cooperation processing of multiple network managements.

[0103] Those of ordinary skill in the art will understand that all or some of the steps in the methods disclosed above, and the functional modules / units in the systems and devices, can be implemented as software, firmware, hardware, and their appropriate combinations. In the hardware implementation, the division between the functional modules / units mentioned above does not necessarily correspond to the division of physical components; for example, one physical component can have multiple functions, or one function or step can be executed by several physical components in cooperation.

Such software can be distributed on a computer-readable medium, which can include a computer storage medium (or non-transitory medium) and a communication medium (or transitory medium). As is well known to those of ordinary skill in the art, the term computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information, such as computer-readable instructions, data structures, program modules, or other data.
