[0026] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] First, the related technologies involved in this disclosure are described:

[0029] Optical layer OAM (Operation Administration and Maintenance): Optical layer OAM is an in-band monitoring technology that monitors single-channel information by adding low-frequency (MHz) modulation (pilot tone) to high-speed (GHz and above) optical wavelengths. Frequency division technology is used to add different modulated pilot tones to different wavelengths, enabling monitoring of multiple channels. This low-frequency information can be extracted through low-cost direct detection at any detection point on the optical path. Low-frequency modulation can be used to load channel information with corresponding content, indicating the characteristics of the channel (such as center wavelength, service rate, source and destination address, etc.). This information is combined into a specific frame format, forming the optical layer OAM overhead.

[0030] Service awareness technology: OTN (Optical Transport Network) electrical layer service access is developing service awareness functions. Based on the acquired L2L3 layer information of the accessed services, this technology enables the activation and scheduling of customer services corresponding to OTN bearer layer services, as well as cloud computing and other complex functional scenarios.

[0031] The boards related to optical layer equipment can support optical power monitoring function points, and implement optical layer OAM information content monitoring at a low cost.

[0032] Optical layer service scheduling can use service-related information to implement service activation and scheduling functions.

[0033] The present disclosure is described below with reference to embodiments:

[0034] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking the operation on a mobile terminal as an example, FIG2 is a hardware structure block diagram of the mobile terminal of the method for processing optical layer services in the embodiment of the present disclosure. As shown in FIG2 , the mobile terminal may include one or more (only one is shown in FIG2 ) processors 202 (the processor 202 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 204 configured to store data, wherein the above-mentioned mobile terminal may also include a transmission device 206 and an input and output device 208 for communication functions. It can be understood by those skilled in the art that the structure shown in FIG2 is only for illustration, and it does not limit the structure of the above-mentioned mobile terminal. For example, the mobile terminal may also include more or fewer components than those shown in FIG2 , or have a configuration different from that shown in FIG2 .

[0035] The memory 204 can be configured to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for processing optical layer services in the embodiment of the present disclosure. The processor 202 executes various functional applications and data processing by running the computer program stored in the memory 204, that is, implements the above-mentioned method. The memory 204 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 204 may further include a memory remotely located relative to the processor 202, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0036] The transmission device 206 is configured to receive or transmit data via a network. Specific examples of the aforementioned network may include a network connection provided by a telecommunications provider. In one embodiment, the transmission device 206 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with other network devices. In one embodiment, the transmission device 206 can be a physical network port, an optical port, or an electrical port, which can communicate with other network devices via an optical fiber or network cable connection.

[0037] The embodiment of the present application can run on the network architecture shown in Figure 3. As shown in Figure 3, the optical layer and the electrical layer actually have information interaction.

[0038] In this embodiment, a method for processing optical layer services running on the network architecture shown in FIG3 is provided. FIG4 is a flow chart of the method for processing optical layer services according to an embodiment of the present disclosure. As shown in FIG4 , the flow chart includes the following steps:

[0039] Step S402, obtaining an optical label in an optical signal from the electrical layer;

[0040] Step S404: obtaining the electrical layer service information carried in the optical label;

[0041] Step S406: Perform service processing at the optical layer based on the service information.

[0042] Among them, the executor of the above steps can be the device on the optical layer side, and each step can be executed by a module or device on the optical layer side, or by different modules or devices respectively, or some steps can be executed by the same module or device.

[0043] In the above embodiment, the business information in the optical label is pre-written by the equipment on the electrical layer side. There can be many specific writing methods. For example, the electrical layer single board optical module can be modulated to write relevant information. Of course, other methods can also be used for writing, which is not limited here.

[0044] In the above embodiment, the service information may also include multiple types of information, for example, it may include information required for optical layer service activation, service demand information, service status information, etc., and specifically which information can be adjusted based on actual needs.

[0045] In the above embodiment, after the optical layer obtains the service information of the electrical layer, it can perform service processing on the optical layer side based on the obtained information, including but not limited to opening the service, adjusting the service, or performing other service processing.

[0046] Through the above embodiments, since the electrical layer carries the service information of the electrical layer in the optical label of the optical signal when sending the optical signal, the optical layer can obtain the service information of the electrical layer from the optical label, and can perform service processing on the optical layer side based on the obtained service information, thereby realizing cross-layer joint processing of optical layer services and electrical layer services, and effectively solving the problem in related scenarios that only optical layer or electrical layer services can be managed and controlled separately, and cross-layer joint processing of optical layer services and electrical layer services cannot be realized.

[0047] In an optional embodiment, before obtaining the optical label in the optical signal from the electrical layer, the method further includes: when it is determined that the device set to monitor the optical signal is a fixed wavelength scheduling device, centrally monitoring the optical signal from the electrical layer device; when it is determined that the device set to monitor the optical signal is a non-fixed wavelength scheduling device, individually monitoring the optical signal from the electrical layer device. In this embodiment, the fixed wavelength scheduling device may be a FOADM (Fixed Optical Add-Drop Multiplexer), and the above-mentioned non-fixed wavelength scheduling device may be a ROADM (Reconfigurable Optical Add-Drop Multiplexer), wherein, compared to ROADM, FOADM can only add and drop fixed wavelength channels and cannot dynamically adjust the settings at will.

[0048] In the above embodiment, the optical layer supports the monitoring of optical layer OAM information of multiple services in hardware (different optical labels have different frequencies and can be detected together), but it is necessary to obtain the optical label information before service scheduling as the basis for service scheduling to guide service scheduling. Among them, for the fixed wavelength scheduling equipment mentioned above, such as coupler, the wavelength path is fixed, and optical layer OAM information monitoring can be centralized, thereby achieving the effect of saving costs and reducing complexity. In addition, for the configurable wavelength scheduling equipment mentioned above, such as WSS, optical switch array, etc., it is necessary to first monitor the optical layer OAM information at the access point to provide the necessary configuration information for the wavelength scheduling equipment before performing service scheduling. In this case, there are certain requirements for the optical label detection position.

[0049] In an optional embodiment, performing service processing at the optical layer based on the service information includes at least one of the following: if the optical layer service is not activated, obtaining first information for activating the optical layer service from the service information, and activating the optical layer service based on the first information; if the optical layer service is activated, obtaining second information indicating the service status of the electrical layer from the service information, and scheduling the optical layer service based on the second information. In this embodiment, the information contained in the frame structure can be predefined in the optical signal to be divided into first information indicating the service activation requirement and second information indicating the service implementation status. Service processing at the optical layer can include activating the service and scheduling the service. The service information required for different operations may vary. It should be noted that, when activating a service, only the first information is generally used. However, when scheduling a service, the first and second information may be used in combination, and, if necessary, other information may be used simultaneously for service scheduling. Furthermore, the specific information included in the first and second information can be flexibly adjusted based on actual conditions.

[0050] In an optional embodiment, obtaining first information for activating the optical layer service from the service information, and activating the optical layer service based on the first information includes: obtaining at least one of the wavelength value and channel bandwidth information from the service information, and determining wavelength resource allocation based on the obtained information; when it is determined that there is no conflict in the wavelength resource allocation, determining topology information based on at least one of the following information included in the service information: source and destination sites, service priority, service delay, and service scheduling requirements, wherein the topology information includes at least one of the following information: service key points, path hop count, and distance requirements; generating and configuring a service topology path based on the topology information; wherein the first information includes the information obtained when determining the wavelength resource allocation, and the information used when determining the topology information. In the above embodiment, when configuring the service topology path, a specific configuration command can be determined based on the determined service topology path, and the specific command can be sent to each execution node to complete the service activation. In addition, it should be noted that the first information may include various types of specific information mentioned in this embodiment, or only part of the various types of specific information mentioned in this embodiment, including which information can be adjusted based on actual business conditions or business activation requirements.

[0051] In an optional embodiment, obtaining the second information for indicating the service status of the electrical layer from the service information, and scheduling the optical layer service based on the second information includes: obtaining the second information for indicating the actual status of the service of the electrical layer from the service information; and scheduling the optical layer service based on the second information when it is determined based on the second information that the service status of the electrical layer has changed. In this embodiment, the service scheduling is triggered by the service information sent by the electrical layer as an example. In addition, in actual applications, there are many ways to trigger the service scheduling. For example, it can also be triggered by changes in optical layer resources and alarm status. It should be noted that no matter which triggering method is used, it is necessary to give priority to high-priority, alarm-free, and high-traffic utilization services. In this embodiment, when performing service scheduling, in addition to using the second information for scheduling, the aforementioned first information and other information obtained by the optical layer can also be referred to.

[0052] In an optional embodiment, after performing service processing at the optical layer based on the service information, the method further includes: when it is determined that the electrical layer is not loaded with the target service, releasing the optical layer resources allocated for the target service. In this embodiment, whether the electrical layer has loaded the target service can be determined by whether the electrical layer has sent an electrical signal. For example, if the electrical layer does not turn on the laser, it means that it has not loaded the target service. In addition, other methods can be used to determine whether the electrical layer has loaded the target service. In addition, after the laser is turned on on the electrical layer board, the wavelength resources of the electrical layer service transmitted will be checked. If a conflict occurs, an alarm will be given. If the blocking capability is available, it can be blocked.

[0053] In an optional embodiment, the method further includes: after acquiring the optical signal, transmitting a processing result after performing target processing on the optical signal to the first port of the electrical layer, indicating to the electrical layer that the optical layer successfully performed the target processing on the optical signal; wherein the optical signal is transmitted by the second port of the electrical layer, and the first and second ports are receiving and transmitting ports on the same or different sides of the same bidirectional service. In this embodiment, the optical layer device has a configurable connection between local add / drop optical paths, supporting direct loopback configuration for add and drop services. Therefore, the loopback function can be used to enable simple interaction between the electrical and optical layer devices, implementing an automatic negotiation service provisioning process. In this embodiment, the optical layer can also transmit the acquired optical label or other information to the first port of the electrical layer. Regardless of the type of information transmitted, the ultimate purpose is to enable information exchange between the two parties, thereby achieving negotiation. In the case of transmitting an optical label, the electrical layer device can determine the interaction status with the optical layer device based on whether it receives no optical label signal, receives an optical label signal transmitted by its own end, or receives an optical label signal transmitted by the other end. The optical layer device can set a loopback based on the received optical label information to indicate that the optical label information has been received and parsed normally, and notify the electrical layer device. By opening up the service, the electrical layer service AZ ports (that is, the receiving and sending ports of the same bidirectional service starting at node A on one side of the service and node Z on the other side of the service, wherein the receiving and sending ports on the same side mentioned above can be a pair of sending and receiving ports on the A node side, or can be a pair of sending and receiving ports on the Z node side, and the receiving and sending ports on different sides mentioned above mean that the receiving port is on the A node side and the sending port is on the Z node side, or the receiving port is on the Z node side and the sending port is on the A node side) can be interconnected. This achieves a simple interaction of optical layer and electrical layer information.

[0054] In an optional embodiment, performing service processing at the optical layer based on the service information includes: after determining that the service has been authenticated at the optical layer, pre-calculating the service topology path at the optical layer based on the service information; and configuring the service topology path when determining that the service needs to be loaded at the optical layer. In this embodiment, the status of the optical layer service can be divided into three types: unactivated, authenticated, and activated. After entering the service authenticated state, the optical label of the received optical signal can contain service information. In this case, the service can be activated based on the service information first, but the optical layer can pre-calculate the route according to the service information in the optical label. When the service needs to be loaded, it can switch to the activated state. The optical layer executes the configuration corresponding to the pre-calculated routing information, which can speed up the service activation.

[0055] The above embodiment mainly describes the processing flow on the optical layer side. The following describes the processing flow on the electrical layer side.

[0056] This embodiment also provides a method for processing optical layer services running on the network architecture shown in FIG3 . FIG5 is a flow chart of another method for processing optical layer services according to an embodiment of the present disclosure. As shown in FIG5 , the process includes the following steps:

[0057] Step S502 : Sending an optical signal carrying the service information of the electrical layer in the optical label to the optical layer, to instruct the optical layer to perform service processing based on the service information after acquiring the service information.

[0058] The execution entity of the above steps may be the equipment on the electrical layer side.

[0059] In the above embodiment, the business information in the optical label is pre-written by the equipment on the electrical layer side. There can be many specific writing methods. For example, the electrical layer single board optical module can be modulated to write relevant information. Of course, other methods can also be used for writing, which is not limited here.

[0060] In the above embodiment, the service information may also include multiple types of information, for example, information required for optical layer service development, service demand information, service status information, etc., and which specific information can be adjusted based on actual needs.

[0061] Through the above embodiments, since the electrical layer carries the service information of the electrical layer in the optical label of the optical signal when sending the optical signal, the optical layer can obtain the service information of the electrical layer from the optical label, and can perform service processing on the optical layer side based on the obtained service information, thereby realizing cross-layer joint processing of optical layer services and electrical layer services, and effectively solving the problem in related technologies that only optical layer or electrical layer services can be managed and controlled separately, and cross-layer joint processing of optical layer services and electrical layer services cannot be realized.

[0062] In an optional embodiment, before the optical signal carrying the electrical layer service information in the optical label is sent to the optical layer, the method further includes: expanding the target frame in the optical label; and writing the service information in the expanded target frame. In this embodiment, the electrical layer device can expand the existing optical label based on the defined format to enable it to support carrying the information required for optical layer scheduling. In the embodiment, the optical label can support multi-frame definition. If one reserved byte is used and it is expanded according to 64 multi-frames, it can support 64-byte content transmission. It should be noted that this expansion method is only an example. In actual applications, more reserved bytes can be used, and when expanding, more multi-frames or fewer multi-frames can be used for expansion.

[0063] In an optional embodiment, the method further includes: determining a reception status of a target optical label at the electrical layer; and determining a processing result of the service processing based on the reception status. This embodiment primarily addresses scenarios where the optical layer configures direct loopback for both add and drop services. The electrical layer can comprehensively determine the current service status based on whether an optical label is received and, if so, the specific port from which the optical label is received.

[0064] In an optional embodiment, determining the result of the service processing based on the receiving state includes: determining that the optical layer has not opened the service corresponding to the service of the electrical layer when it is determined that the electrical layer has not received the target optical label; determining that the optical layer has authenticated the service corresponding to the service of the electrical layer when it is determined that the target optical label received by the local receiving port of the electrical layer is the optical label sent by the local sending port, wherein the local receiving port and the local sending port are the receiving and sending ports on the same side of the same bidirectional service; determining that the optical layer has opened the service corresponding to the service of the electrical layer when it is determined that the target optical label received by the local receiving port of the electrical layer is the optical label sent by the opposite sending port, wherein the local receiving port and the opposite sending port are the receiving and sending ports on different sides of the same bidirectional service. In this embodiment, the loopback function can be used to implement simple interaction between electrical layer equipment and optical layer equipment, and realize the automatic negotiation service activation process.

[0065] The above is a description of the processing on the optical layer side and the electrical layer side respectively. The following is an overall description of the present disclosure in conjunction with specific embodiments:

[0066] FIG6 is a flowchart of sorting optical layer services according to an embodiment of the present disclosure. As shown in FIG6 , the process includes the following steps:

[0067] S602, in a scenario where the electrical layer is connected to the optical layer and the optical layer is separated, the electrical layer service writes service information into the optical label;

[0068] S604: The electrical layer device transmits the relevant service information to the optical layer via an optical signal carrying the optical label.

[0069] S606, the optical layer service device obtains the electrical layer service information from the optical label and transmits it to the optical layer service controller;

[0070] S608 , the optical layer service controller performs optical layer activation, scheduling, and other operations on the carried electrical layer service based on the electrical layer service information obtained from the optical label.

[0071] The following is a detailed description of the above steps:

[0072] In the above S602, the following information is mainly considered when writing the electrical layer service information into the optical label:

[0073] 1. Format requirements: The existing optical label format is expanded to support the information required for optical layer scheduling.

[0074] 2. Content: Information required for optical layer service provisioning. In addition to information already defined in optical labels in related technologies, such as wavelength, channel bandwidth, and source / destination sites, this information may also include service requirement information such as priority, service latency, and service scheduling requirements. It may also include service status information such as service traffic and service alarm status. This information provides the information required for service provisioning and scheduling.

[0075] In the optical label technology in the related art, multi-frame definition can be supported. If one reserved byte is used and expanded according to 64 multi-frames, 64-byte content transmission can be supported. The possible transmission content and definitions are listed below.

[0076] The information mainly includes:

[0077] Handshake information (i.e., the content shown in Table 1): Since there is no direct interaction between electrical layer and optical layer control, adding authentication information can ensure that relevant processing can only be performed after authorization, thereby ensuring security.

[0078] Table 1

[0079] Request type (i.e., the content shown in Table 2): distinguishes whether there is a business status. When performing different operations on the business, different attributes need to be paid attention to.

[0080] Table 2

[0081] Service configuration information (ie, the content shown in Table 3): specific service configuration related information, including specific resource information, topology information, and path calculation requirements.

[0082] Table 3

[0083] Actual business status (ie, the content shown in Table 4): the actual business status, and the created business can be evaluated and adjusted according to the actual status.

[0084] Table 4

[0085] In the above definition, the expandable field is calculated as 64 bits, and the total length does not exceed the length of a single byte * 64 multiframes. The above definition is only an example, not the only solution. The content is optional, expandable, and not mandatory.

[0086] In the above S606, the optical layer service device obtains the electrical layer service information from the optical label, which may specifically include the following:

[0087] Optical layer service equipment, which performs cross-scheduling of optical layer signals and interconnects with electrical layer services, needs to have optical label detection capabilities in the add / drop units to obtain service-related information.

[0088] In terms of hardware, it supports monitoring the optical layer OAM information of multiple services together (different optical labels have different frequencies and can be detected together), but it is necessary to obtain the optical label information before service scheduling as the basis for service scheduling to guide service scheduling.

[0089] For fixed wavelength scheduling equipment, such as couplers, the wavelength path is fixed, and optical layer OAM information monitoring can be centralized to save costs and reduce complexity. This situation can be seen in Figure 7.

[0090] For configurable wavelength scheduling equipment, such as WSS and optical switch arrays, it is necessary to first monitor the optical layer OAM information at the access point to provide the necessary configuration information for the wavelength scheduling equipment before performing service scheduling. There are requirements for the optical label detection position. For this situation, please refer to Figure 8.

[0091] After obtaining the access electrical layer service information, it is forwarded to the controller for unified scheduling and processing.

[0092] In the above S608, the controller performs service configuration according to service requirements, which mainly includes the following contents:

[0093] Detect the optical label of the optical layer accessing the electrical layer service and obtain the service information. Calculate the route based on the service information and schedule the opening of the optical layer service. The following scenarios are explained:

[0094] For activation scenarios:

[0095] Obtain the necessary information for activation, namely wavelength value and channel bandwidth information, and determine wavelength resource allocation. If there is a conflict, an alarm will be issued.

[0096] When wavelength allocation does not conflict, topology constraints such as service key points, path hop count, and distance requirements are determined based on service configuration information such as source and destination sites, priority, service delay, and service scheduling requirements.

[0097] Calculate and generate the service topology path, convert it into specific configuration commands, and issue them to each execution node to complete service activation.

[0098] For scheduling scenarios:

[0099] Perform service scheduling based on service status information.

[0100] Based on the optical layer resources and alarm status, priority is given to high-priority, alarm-free, and high-traffic utilization services.

[0101] Optical layer service scheduling operations can be triggered by changes in optical layer resources and alarm status, or by changes in information provided by customer electrical layer services.

[0102] For example, if an optical layer failure occurs and the original path becomes ineffective, the optical layer related to the failed path also needs to be rescheduled.

[0103] For example, if the business priority changes, the business path can be adjusted according to the algorithm.

[0104] For example, if the service level requirements change, the optical layer parameters can be adjusted to increase or decrease the service OSNR (Optical Signal-to-Noise Ratio) margin.

[0105] For example, if the service alarm status changes, the service level can be adjusted for the alarm service and the routing can be recalculated.

[0106] When no services are loaded, optical layer resources can be released and no scheduling is performed.

[0107] After the laser is turned on on the electrical layer board, the wavelength resources of the electrical layer services transmitted are checked. If a conflict occurs, an alarm is given. If blocking capability is available, blocking is performed.

[0108] For the auto-negotiation process in a non-service scenario:

[0109] Prerequisite: In the optical layer equipment, there is a configurable connection between the local add and drop optical paths, which supports direct loopback configuration of add and drop services.

[0110] The loopback function can be used to implement simple interaction between electrical layer devices and optical layer devices (mainly including the electrical layer device performing a sending operation, the optical layer device performing a scheduling processing operation, and the electrical layer device then performing a receiving operation. The specific service status determined can be seen in Table 5), realizing the automatic negotiation service activation process.

[0111] Table 5

[0112] In the above Table 5, the electrical layer device can determine the interaction status with the optical layer device based on whether it receives no optical label signal, receives an optical label signal sent by the local end, or receives an optical label signal sent by the remote end.

[0113] The optical layer device can set a loopback based on the received optical label information to indicate that the optical label information has been received and parsed normally, and notify the electrical layer device. By opening up the service, the AZ ports of the electrical layer service can be interconnected.

[0114] A simple interaction between optical layer and electrical layer information is achieved.

[0115] After entering the authenticated state, the optical label can contain service information, but service provisioning is not performed. The optical layer pre-calculates routes based on the service information in the optical label. When a service is required, the optical layer switches to the enabled state and executes the configuration corresponding to the pre-calculated route information, which can speed up service provisioning.

[0116] In addition, the transition conditions of the above three states of the service can be seen in Figure 9.
