[0019] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the information transmission method, IP device, OTN device, and computer-readable storage medium provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0020] Hereinafter, example embodiments will be described more fully with reference to the accompanying drawings, but the example embodiments may be embodied in different forms, and the present disclosure should not be construed as limited to the embodiments set forth herein. These embodiments are provided to make the present disclosure more thorough and complete and to enable those skilled in the art to fully understand the scope of the present disclosure.

[0021] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0022] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] The terms used herein are used only to describe specific embodiments and do not limit the present disclosure. As used herein, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise. It will also be understood that when the terms "comprising" and / or "made of" are used in this specification, they specify the presence of specific features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or possible addition of one or more other features, wholes, steps, operations, elements, components, and / or groups thereof.

[0024] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined as such herein.

[0025] In this disclosure, unless otherwise specified, the following technical terms should be understood as follows:

[0026] OTN equipment refers to optical transmission network equipment that includes at least one of ODUk (Optical Channel Data Unit k), ODUflex (Optical Channel Data Unit Flex, an optical channel data unit with flexible capacity), an optical channel (OCH) of equal sub-wavelength, and a unit with wavelength-level switching capability.

[0027] The optical layer in OTN equipment can be used for processing such as modulation and demodulation of optical signals, while the electrical layer can be used to realize the conversion of optical and electrical signals.

[0028] IP devices are devices with IP communication functions, such as routers and switches. They can connect to OTN devices and interact with OTN devices through optical signals.

[0029] Figure 1 illustrates an application scenario for related technologies. Referring to Figure 1, in some related technologies, service signals are transmitted between IP devices and OTN devices using gray optical intercommunication at the electrical layer. The IP and OTN devices each manage and configure service information related to the interconnected ports through their respective network management modules. The OTN device's electrical layer reprocesses the gray optical signal transmitted by the IP device and generates a color optical signal through forward error correction (FEC) at the electrical layer. The color optical signal then passes through the optical layer's combiner / demultiplexer and optical amplifier (OA) for optical fiber transmission, increasing transmission distance and single-fiber transmission bandwidth. The transmission code type, FEC, wavelength, optical power, and spectral width of the color optical module required to generate the color optical signal can be directly obtained and configured at the electrical layer. However, since this service signal transmission method requires passing through the electrical layer of the OTN device, FEC must be added to the electrical layer of the OTN device, resulting in higher network construction costs.

[0030] In some related technologies, IP devices directly load color optical modules, and the optical layers of IP devices and OTN devices use color optical intercommunication to transmit service signals. Although this can save the electrical layer of OTN devices and reduce network construction costs, the IP devices and OTN devices cannot achieve collaboration. Although service signals can be transmitted, the transmission code type, FEC, wavelength, optical power, spectrum width and other information of the color optical modules required by the OTN devices cannot be obtained and set in collaboration with the IP devices.

[0031] Therefore, there is an urgent need to provide a solution that can achieve collaboration between IP and OTN devices at a low cost while reducing the difficulty of implementation. The present disclosure can directly receive OAM (Operation Administration and Maintenance) information from IP devices through the optical layer of OTN devices, and directly send control commands to IP devices through the optical layer of OTN devices, thereby achieving collaboration between OTN and IP devices.

[0032] Figure 2 is a flow chart of an information transmission method for an IP device provided by the present disclosure. In a first aspect, referring to Figure 2 , the present disclosure provides an information transmission method for an IP device, wherein the IP device includes a color light module, and the method includes steps S11 and S12.

[0033] S11. Determine a first top modulation signal according to OAM information, where the first top modulation signal carries the OAM information.

[0034] S12: Send the first top modulation signal as an optical associated signal in a first color optical signal to an optical transmission network OTN device.

[0035] In this embodiment, a color optical module is set in the IP device, and the first modulation signal carrying OAM information is sent to the optical layer of the OTN device as the optical associated signal of the first color optical signal through the IP device. There is no need to pass through the electrical layer of the OTN device or add an upper-layer network management. The OAM information can be directly transmitted to the optical layer of the OTN device, thereby realizing the collaboration between the OTN device and the IP device and reducing the network construction cost.

[0036] In some implementations, step S11 includes: performing modulation processing on the OAM information to obtain the first modulation signal.

[0037] In some embodiments, the color light module includes 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. The IP device can modulate the OAM information using the coherent DSP chip or the SiP VOA / InP SOA optical chip to generate a first modulation signal.

[0038] It is worth noting that, since the color optical module of the IP device has no additional communication transmission channel for exchanging other information except for being configured for color optical intercommunication with the OTN device, the first pilot tone signal carrying OAM information is transmitted to the OTN device as an optical accompanying signal of the first color optical signal, that is, the first color optical signal is pilot-tone processed, and a low-speed optical accompanying signal (i.e., the first pilot tone signal) is generated at the transmitting end for the main signal of the wavelength channel (i.e., the first color optical signal) using frequency modulation or amplitude modulation technology. The first pilot tone signal does not occupy the service channel of the first color optical signal.

[0039] In some implementations, the OAM information includes at least one of: transmission code type, forward error correction (FEC), wavelength, optical power, and spectrum width.

[0040] In the embodiments of the present disclosure, the OAM information is not fixed and can be adjusted according to actual conditions.

[0041] In some embodiments, the color optical module of the IP device includes a first optical layer OAM protocol agent unit configured to read OAM information.

[0042] In some embodiments, the information transmission method further includes: upon detecting a second top modulation signal, determining a control command based on the second top modulation signal, wherein the second top modulation signal carries the control command, and the second top modulation signal is an optical associated signal in the second color light signal.

[0043] In the present disclosure, because the IP device's color optical module, in addition to being configured for color optical intercommunication with the OTN device, lacks additional communication transmission channels for exchanging other information, when the OTN device sends a control command to the IP device's color optical module, a second top-modulated signal carrying the control command is transmitted to the IP device's color optical module as an optical associated signal of the second color optical signal. The second top-modulated signal does not occupy the service channel of the second color optical signal, thereby enabling remote control of the IP device by the OTN device. In some embodiments, the control command includes at least one of module configuration information, transmission performance alarm information, and a module reset instruction.

[0044] In some implementations, the IP device can demodulate the second modulation signal using a coherent DSP chip or a SiP VOA / InP SOA optical chip to obtain a control command. Accordingly, the first optical layer OAM protocol proxy unit of the IP device's color optical module can perform protocol conversion on the control command, allowing the IP network management system to obtain the control command from the OTN device.

[0045] In some embodiments, the IP device obtains the second top adjustment signal through detection by a photoelectric detection device. The present disclosure does not impose any particular limitation on the photoelectric detection device, which may be a sensor, a laser detector, or the like.

[0046] In addition, since the IP device and the OTN device interact with each other through color optical intercommunication, the second top modulation signal detected by the IP device is an optical signal. The color optical module of the IP device also includes a photoelectric conversion function module configured to convert the detected optical signal (i.e., the second top modulation signal) into an electrical signal.

[0047] In the present disclosure, the IP device sends a first modulation signal carrying OAM information as an optical associated signal of the first color optical signal to the optical layer of the OTN device, and the OTN device sends a second modulation signal carrying a control command as an optical associated signal of the second color optical signal to the color optical module of the IP device. 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 set up an additional upper-layer network management. This not only realizes the collaboration between IP and OTN devices, but also reduces the cost of network construction.

[0048] FIG3 is a flow chart of an information transmission method for OTN equipment provided by the present disclosure. In a second aspect, referring to FIG3 , the present disclosure provides an information transmission method for OTN equipment, comprising: step S21.

[0049] S21: When the first top-modulation signal is detected, determine OAM information according to the first top-modulation signal, where the first top-modulation signal carries the OAM information and the first top-modulation signal is an optical associated signal in a first color optical signal.

[0050] In some implementations, determining the OAM information according to the first top modulation signal in step S21 includes: demodulating the first top modulation signal to obtain the OAM information.

[0051] In the present disclosure, the optical layer of an OTN device can detect a first top-modulated signal using a photoelectric detection device. The detected first top-modulated signal is then demodulated to obtain the OAM information transmitted along with the first top-modulated signal. In some embodiments, the optical layer of the OTN device also includes a second optical layer OAM protocol agent configured to perform protocol conversion on the OAM information. The second optical layer OAM protocol agent converts the demodulated OAM information and uploads it to the OTN network management system, allowing operations and maintenance personnel to obtain the OAM information by querying the OTN network management system. Furthermore, the wavelength port, filter bandwidth, gain, or attenuation, etc. of the OTN optical layer's combiner / demultiplexer can be set based on the OAM information.

[0052] The present disclosure does not impose any particular limitation on the photoelectric detection device; it may be a sensor, laser detector, or the like. It is worth noting that the first top-modulated signal is transmitted from the IP device to the OTN device along with the first color optical signal. If the OTN device detects the first top-modulated signal, the transmission of the first color optical signal and the first top-modulated signal will not be affected. In other words, the first top-modulated signal will continue to be transmitted along with the first color optical signal within the OTN device.

[0053] In addition, since the IP device and the OTN device interact with each other through color optical intercommunication, the first top modulation signal detected by the OTN device is an optical signal. Accordingly, the optical layer of the OTN device also includes an optoelectronic conversion function module configured to convert the detected optical signal (i.e., the first top modulation signal) into an electrical signal.

[0054] In some embodiments, the information transmission method further includes: determining a second top modulation signal according to the control command, wherein the second top modulation signal carries the control command; and sending the second top modulation signal as an optical associated signal in the second color optical signal to the IP device.

[0055] In the present disclosure, the second modulation signal carrying the control command is sent to the IP device as an optical accompanying signal of the second color optical signal through the optical layer of the OTN device. The control command can be directly transmitted to the optical layer of the IP device without passing through the electrical layer of the OTN device or adding an upper-layer network management, thereby realizing the collaboration between the OTN device and the IP device and reducing the network construction cost.

[0056] In some implementations, the control command is obtained from an OTN network manager on an upper layer of the OTN device. The OTN network manager sends at least one of module configuration information, transmission performance alarm information, and module reset instructions to the second optical layer OAM protocol agent unit to obtain the control command.

[0057] In some embodiments, the second color optical signal is a service signal or a basic optical signal transmitted by the OTN device to the IP device; when the second color optical signal is a basic optical signal, before sending the second top-modulated signal as an optical associated signal in the second color optical signal to the IP device, the information transmission method further includes: adjusting the optical power of the DC optical signal through a variable optical attenuator to obtain the basic optical signal.

[0058] In this disclosure, the optical layer of the OTN device requires an optical signal as a basis for transmitting the second top-modulated signal to the IP device. Therefore, if the OTN device has a service signal to transmit to the IP device, it performs top-modulation on that service signal, allowing the second top-modulated signal to be sent to the IP device as an optical accompanying signal of the service signal. If the OTN device does not have a service signal to transmit to the IP device, the OTN device can generate a base optical signal to transmit the second top-modulated signal to the IP device as an optical accompanying signal within the base optical signal. The DC optical signal is obtained by processing out-of-band DC light through a 1xN power splitter, but this disclosure is not limited to this.

[0059] The present disclosure does not impose any particular limitation on the method of generating the basic optical signal. As an example, after the out-of-band DC light is split into multiple optical signals by a 1×N power splitter, the basic optical signal is obtained by processing through a filter.

[0060] In some implementations, the optical layer of the OTN device uses at least one of an eVOA (Electrically Variable Optical Attenuator) and a SOA (Semiconductor Optical Amplifier) ​​to use the second top-modulated signal as an optical associated signal in the basic optical signal to perform top-modulation processing on the basic optical signal.

[0061] In the present disclosure, the optical layer of the OTN device detects the optical associated signal of the first color optical signal (i.e., the first top modulation signal carrying OAM information). At the same time, when the optical layer of the OTN device needs to send a control command to the IP device, the OTN device sends the second top modulation signal carrying the control command as the optical associated signal of the second color optical signal to the color optical module of the IP device, thereby realizing the collaboration 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 set up an additional upper-layer network management, thereby reducing the network construction cost.

[0062] In the third aspect, referring to Figure 4, the present disclosure provides an IP device, including: a color light module, including: a laser unit and a first collaborative unit; the laser unit includes a first sending subunit; the first collaborative unit includes: at least one first processing subunit 401, a first memory 402 and a first receiving subunit; the first memory 402 stores at least one computer program, and when the at least one computer program is executed by the at least one first processing subunit 401, the first sending subunit and the first receiving subunit, the at least one first processing subunit 401, the first sending subunit and the first receiving subunit implement the above-mentioned information transmission method.

[0063] In some implementations, the IP device further includes at least one first I / O interface 403 connected between the first processing subunit 401 and the first memory 402 , and configured to implement information interaction between the first processor 401 and the first memory 402 .

[0064] The first processing sub-unit 401 is a device with data processing capabilities, including but not limited to a central processing unit (CPU); the first memory 402 is a device with data storage capabilities, including but not limited to random access memory (RAM, more specifically SDRAM, DDR, etc.), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), and flash memory (FLASH); the first I / O interface (read-write interface) 403 is connected between the first processing sub-unit 401 and the first memory 402, and can realize information interaction between the first processing sub-unit 401 and the first memory 402, which includes but is not limited to a data bus (Bus), etc.

[0065] In a fourth aspect, referring to Figure 5, the present disclosure provides an OTN device, including: a wavelength splitter / combiner module, including: a color light detection unit and a second collaborative unit; the color light detection unit includes a second receiving subunit; the second collaborative unit includes: at least one second processing subunit 501, a second memory 502, and a second sending subunit; the second memory 502 stores at least one computer program, and when the at least one computer 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 above-mentioned information transmission method.

[0066] In some implementations, the OTN device further includes at least one second I / O interface 503 connected between the second processing subunit 501 and the second memory 502 and configured to implement information interaction between the second processing subunit 501 and the second memory 502 .

[0067] The second processing sub-unit 501 is a device with data processing capabilities, including but not limited to a central processing unit (CPU); the second memory 502 is a device with data storage capabilities, including but not limited to random access memory (RAM, more specifically SDRAM, DDR, etc.), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), and flash memory (FLASH); the second I / O interface (read-write interface) 503 is connected between the second processing sub-unit 501 and the second memory 502, and can realize information interaction between the second processing sub-unit 501 and the second memory 502, including but not limited to a data bus (Bus), etc.

[0068] In a fifth aspect, referring to FIG6 , the present disclosure provides a computer-readable storage medium having a computer program stored thereon, and the computer program is executed by a processor, so that the processor implements the above-mentioned information transmission method.

[0069] In order to enable those skilled in the art to more clearly understand the technical solutions provided by the present disclosure, the technical solutions provided by the present disclosure are described in detail below through specific implementation methods:

[0070] FIG7 is a schematic diagram of the structure of an OTN device and an IP device provided by the present disclosure. FIG8 is a schematic diagram of the structure of a wavelength splitter / combiner module in an OTN device and a color light module of an IP device provided by the present disclosure. Referring to FIG7 and FIG8, as an example, the color light module of the IP device includes a first sub-component consisting of a laser unit and a first collaborative unit, the laser unit includes a first transmitting sub-unit (Tx), and the first collaborative unit includes a first receiving sub-unit (Rx) and a first processing sub-unit. The first sub-component can send OAM information to the OTN device through interaction with the OTN device, and can also send the control information that needs to be executed (such as control commands) to the color light module, and upload the information that needs to be fed back (such as feedback information of the control command) to the OTN device, thereby realizing remote management of the IP device through the OTN device.

[0071] The optical layer of the OTN device includes a second sub-component consisting of a color light detection unit and a second coordination unit. The color light detection unit includes a second receiving sub-unit for photoelectric detection, and the second coordination unit includes a second processing sub-unit. The second sub-component can send OTN device management and control information (such as control commands) to the first sub-component of the IP device. It can also receive OAM information sent by the first sub-component of the IP device and feed it back to the OTN network management.

[0072] The process of transmitting and receiving OAM information between the color optical module of the IP device and the optical layer of the OTN device through the first and second sub-components is as follows: the first transmitting sub-unit in the first sub-component adds a first top-modulation signal to the first color optical signal via a coherent DSP chip or a SiP VOA / InP SOA optical chip. The first top-modulation signal is obtained by modulating the OAM information. The first top-modulation signal carries the fixed identifier of the first color optical signal and the burst-rewritable OAM information.

[0073] The second receiving subunit in the second subcomponent performs photoelectric detection, and when detecting the first top modulation signal, demodulates the first top modulation signal to obtain OAM information, and feeds the OAM information back to the OTN network management of the upper layer of the OTN device.

[0074] The process of the color optical module of the IP device and the optical layer of the OTN device transmitting and receiving control commands through the first sub-component and the second sub-component is as follows: the second collaborative unit in the second sub-component also includes a second sending sub-unit, and the second processing sub-unit loads the second top-modulated signal on top of the second color optical signal through fast VOA or SOA. The second top-modulated signal is sent by the second sending sub-unit to the color optical module of the IP device as an optical accompanying signal of the second color optical signal. In the presence of a service signal, the service signal can be used as the second color optical signal accompanying the second top-modulated signal. In the absence of a service signal, the out-of-band DC light 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 accompanying the second top-modulated signal to achieve signaling interaction. The basic optical signal is provided by the out-of-band DC light through a 1xN power splitter.

[0075] The first collaborative unit in the first sub-component also 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 modulation signal is detected, it demodulates the second top modulation signal through a coherent DSP chip or SiP VOA / InP SOA optical chip to obtain a control command. After demodulating the control command, the first processing sub-unit in the first sub-component can be used as an optical layer OAM protocol agent, that is, to execute the control command issued by the OTN device to realize the interaction between the color optical module and the OTN device. The control command can include basic operations such as configuration, query, and reset, or it can include active operations such as supporting module attributes, performance alarms, and closed-loop optimization.

[0076] It is worth noting that by adding a subcomponent (e.g., a first subcomponent and a second subcomponent) inside the color optical module and the splitter / combiner module of the OTN device, and by loading the top modulation signal (e.g., a first top modulation signal and a second top modulation signal) on the color optical signal (e.g., a first color optical signal and a second color optical signal) communicated between the IP device and the OTN device, the OTN device can remotely manage the color optical module on the IP device, thereby realizing the collaboration of IP and OTN devices. All management and control can be executed through the OTN network management at the upper layer of the OTN device, which effectively reduces the difficulty of implementing collaborative processing by multiple network managements.

[0077] It will be appreciated by those skilled in the art that all or some of the steps in the method disclosed above, and the functional modules / units in the device can be implemented as software, firmware, hardware, and appropriate combinations thereof. In a hardware implementation, the division between the functional modules / units mentioned in the above description does not necessarily correspond to the division of physical components; for example, a physical component may have multiple functions, or a function or step may be performed by several physical components in cooperation.

Such software may be distributed on a computer-readable medium, which may include a computer storage medium (or non-transitory medium) and a communication medium (or temporary medium). As is well known to those skilled 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). Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can be accessed by a computer.
