[0133] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0134] It should be noted that, in the embodiments of this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, in the embodiments of this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0135] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.

[0136] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

[0137] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0138] An all-optical network refers to a network where all communication functions are performed directly at the optical layer, meaning signal transmission, switching, and processing occur directly in the optical domain. In an all-optical network, a node is an optical node, and common optical nodes include optical transmitters, optical receivers, optical amplifiers, optical connectors, optical splitters, and optical attenuators. Service signals are transmitted between optical nodes via optical fibers.

[0139] In an all-optical network, each service is configured with a dedicated wavelength, which is then used to transmit that service. Typically, bidirectional service exists between two nodes. For example, refer to... Figure 1 , Figure 1 This diagram illustrates a bidirectional service between node A and node Z. With node A as the source node and node Z as the destination node, the service in one direction is called service S1. With node Z as the source node and node A as the destination node, the service in the other direction is called service S2. Service S2 is called the reverse service of service S1, and similarly, service S1 is called the reverse service of service S2. Services S1 and S2 may or may not be related. For service S1, the optical link involves the following nodes: node A → node B → node C → node Z; for service S2, the optical link involves the following nodes: node Z → node C → node B → node A. Service S1 uses a dedicated wavelength for transmission. For ease of service management, service S2 uses the same dedicated wavelength as service S1 for transmission.

[0140] Currently, configuring dedicated wavelengths for services presents the following problems:

[0141] Question 1: In an optical link, each node can use different wavelengths. How to select a wavelength suitable for all nodes in the optical link for the service is a problem that needs to be solved.

[0142] like Figure 1As shown, the optical link from node A to node Z passes through multiple nodes (i.e., nodes B and C). Each node on the optical link has service up and / or service down nodes, where service up refers to the node receiving the service and service down refers to the node sending the service. Each service occupies a wavelength; therefore, the wavelength usage at each node on the optical link may be different. On the optical link from node A to node Z, a certain wavelength may be used by an intermediate node first, causing that wavelength to be unable to reach node Z. For example, node A uses a certain wavelength to send a service to node B; node B finds that the wavelength has already been used on the link between node B and node C, so node B can no longer use the wavelength to send the service from node A. Therefore, the service from node A cannot be sent to node Z using this wavelength. Thus, it is necessary to select a wavelength applicable to all nodes in the optical link to send the service, for example, selecting a wavelength applicable to all nodes between node A and node Z.

[0143] Question 2: After configuring a wavelength for a service in one direction, do we need to configure the same wavelength for a service in another direction?

[0144] like Figure 1 As shown, after configuring a wavelength for transmitting service S1 on the optical link from node A to node Z, it is also necessary to configure a wavelength for transmitting service S2 on the optical link from node Z to node A, and the wavelength for transmitting service S2 is the same as the wavelength for transmitting service S1.

[0145] To address at least some of the aforementioned problems, the following technical solutions based on embodiments of this application are proposed.

[0146] The following describes a frame format proposed in the embodiments of this application. It should be noted that the following technical solutions of the embodiments of this application can be implemented in any combination with the content of the frame format, and all of them fall within the protection scope of the embodiments of this application.

[0147] This application proposes a frame format, which can be called the OAM link layer frame format, or simply the optical layer OAM frame format, or simply the OAM frame format. In the following description, this frame format will be referred to as the OAM frame format.

[0148] As an example, Table 1 below shows the structure of the OAM frame format. The OAM frame format is a block-based 64-byte format, which can be extended using multiframes. It should be noted that the length of each field in the OAM frame format given in Table 1 is an optional implementation method. The length of each field is not limited to the length given in Table 1 and can be defined as other lengths.

[0149] 2 bytes 1 byte 2 bytes 1 byte 1 byte 29 bytes 16 bytes 12 bytes

[0150] Table 1

[0151] The meanings of each field in the OAM frame format in Table 1 above can be found in Table 2 below.

[0152]

[0153]

[0154] Table 2

[0155] In this embodiment of the application, the information carried within the OAM frame can be referred to as OAM information.

[0156] In some alternative implementations, OAM information can be transmitted carried within the service signal. Specifically, OAM information can be loaded into the service signal in the following ways:

[0157] 1) Load the service information onto a carrier with the target wavelength to obtain the first signal;

[0158] 2) Load the OAM information onto a carrier wave of a specific frequency to obtain a second signal;

[0159] Here, the carrier wave at a specific frequency can be a low-frequency sine wave signal or a cosine wave signal. The second signal can also be called the tuning signal.

[0160] 3) Load the second signal onto the first signal to obtain the service signal.

[0161] The service signals obtained through the above methods carry OAM information.

[0162] In some alternative implementations, OAM information can be transmitted carried in the wavelength signal. Specifically, OAM information can be loaded into the wavelength signal in the following ways:

[0163] 1) Load the OAM information onto a carrier wave of a specific frequency to obtain a second signal;

[0164] Here, the carrier wave at a specific frequency can be a low-frequency sine wave signal or a cosine wave signal. The second signal can also be called the tuning signal.

[0165] 2) Load the second signal onto a carrier wave with the target wavelength to obtain a wavelength signal.

[0166] The wavelength signal obtained in the above manner carries OAM information.

[0167] It should be noted that the wavelength ID in the OAM information indicates the target wavelength.

[0168] Figure 2This is a flowchart illustrating the configuration method for optical network services provided in the embodiments of this application. Figure 1 It is used in management and control platforms, such as Figure 2 As shown, the configuration method for the optical network service includes the following steps:

[0169] Step 201: Receive a service request message sent by the source node, the service request message being used to request the establishment of a service between the source node and the destination node.

[0170] In this embodiment of the application, when the source node has a service to transmit to the destination node, the source node sends a service request message to the management and control platform. Correspondingly, the management and control platform receives the service request message sent by the source node. The service request message is used to request the establishment of a service between the source node and the destination node.

[0171] Here, the source node refers to the starting node of the service transmission, and the destination node refers to the ending node of the service transmission.

[0172] Step 202: Determine the optical link used by the service, and determine the target wavelength used by the service based on the wavelengths used and / or unused by each node on the optical link.

[0173] In this embodiment of the application, the management and control platform plans an optical link for the service. The optical link includes a source node, a destination node, and one or more intermediate nodes.

[0174] by Figure 1 For example, the optical link planned by the management platform for the business is: Node A → Node B → Node C → Node Z, where the source node is Node A, the destination node is Node Z, and there are two intermediate nodes between Node A and Node Z, namely Node B and Node C.

[0175] In this embodiment, the management platform determines the target wavelength used by the service based on the wavelengths used and / or unused by each node on the optical link. Specifically, the management platform determines the wavelengths used and / or unused by each node on the optical link; it then determines wavelengths unused by all nodes on the optical link based on the wavelengths used and / or unused by each node, and identifies these unused wavelengths as the target wavelengths used by the service.

[0176] For example, the optical link involves nodes A, B, C, and Z. Among them, the unused wavelengths of node A are wavelength 1, wavelength 2, and wavelength 3; the unused wavelengths of node B are wavelength 1, wavelength 2, and wavelength 5; the unused wavelengths of node C are wavelength 1, wavelength 4, and wavelength 5; and the unused wavelengths of node Z are wavelength 1, wavelength 3, and wavelength 6. The management platform determines that wavelength 1 is the wavelength that is not used by any of the nodes and identifies wavelength 1 as the target wavelength for service use.

[0177] In this embodiment of the application, the management platform can determine the wavelengths used and / or unused by each node on the optical link in the following ways:

[0178] Acquire the first OAM information sent by each node on the optical link, the first OAM information being used to determine the wavelengths used and / or unused by the node;

[0179] The wavelengths used and / or unused by each node on the optical link are determined based on the first OAM information sent by each node on the optical link.

[0180] Here, each node on the optical link sends OAM information, referred to as the first OAM information. This OAM information is carried within an OAM frame, the content of which can be found in the aforementioned description. The wavelength ID in the OAM information indicates the wavelength of the signal carrying that OAM information; this wavelength is also the wavelength already used by the node.

[0181] Based on the OAM information sent by each node on the optical link, the management platform can determine the wavelengths that the nodes have used. Furthermore, it can also determine the wavelengths that the nodes have not used based on the wavelengths that the nodes have used. Based on the wavelengths that each node on each optical link has not used, the management platform determines the wavelengths that are not used by all nodes, and then determines the wavelengths that are not used by all nodes as the target wavelengths used by the service.

[0182] Step 203: Send a service configuration message to the source node. The service configuration message includes the configuration information of the target wavelength and the configuration information of the optical link.

[0183] In this embodiment, the optical control platform sends a service configuration message to the source node. The service configuration message includes configuration information for the target wavelength and configuration information for the optical link. Specifically, the optical control platform sends second OAM information to the source node, and this second OAM information carries the service configuration message.

[0184] Here, the optical control platform sends OAM information, referred to as the second OAM information. The second OAM information is carried in an OAM frame, wherein the OAM frame includes:

[0185] The first field is used to indicate the wavelength identifier of the target wavelength;

[0186] The second field is used to indicate the port information of each node in the optical link.

[0187] Furthermore, the OAM frame also includes at least one of the following:

[0188] The third field is used to indicate the start position of the OAM frame;

[0189] The fourth field is used to indicate whether the OAM frame is a multiframe and its position within the multiframe;

[0190] The fifth field is used to indicate the length of the second field;

[0191] The sixth field is used to indicate the frame checksum;

[0200] The technical solution of this application embodiment realizes automatic wavelength selection between source and destination nodes through optical layer OAM information, thereby improving the degree of service automation.

[0201] Figure 3 This is a flowchart illustrating the configuration method for optical network services provided in the embodiments of this application. Figure 2 Applied to the source node, such as Figure 3 As shown, the configuration method for the optical network service includes the following steps:

[0202] Step 301: Send a service request message to the management and control platform. The service request message is used to request the establishment of a service between the source node and the destination node.

[0203] In this embodiment of the application, when the source node has a service to transmit to the destination node, the source node sends a service request message to the management and control platform. The service request message is used to request the establishment of a service between the source node and the destination node.

[0204] Here, the source node refers to the starting node of the service transmission, and the destination node refers to the ending node of the service transmission.

[0205] Step 302: Receive the service configuration message sent by the management and control platform. The service configuration message includes the configuration information of the target wavelength and the configuration information of the optical link.

[0206] In this embodiment, the source node receives a service configuration message sent by the management and control platform. The service configuration message includes configuration information for the target wavelength and configuration information for the optical link. Specifically, the source node receives second OAM information sent by the management and control platform, the second OAM information carrying the service configuration message.

[0207] Here, the second OAM information is carried in an OAM frame, wherein the OAM frame includes:

[0208] The first field is used to indicate the wavelength identifier of the target wavelength;

[0209] The second field is used to indicate the port information of each node in the optical link.

[0210] Furthermore, the OAM frame also includes at least one of the following:

[0211] The third field is used to indicate the start position of the OAM frame;

[0212] The fourth field is used to indicate whether the OAM frame is a multiframe and its position within the multiframe;

[0213] The fifth field is used to indicate the length of the second field;

[0214] The sixth field is used to indicate the frame checksum;

[0215] The seventh field is used to indicate the optical communication channel;

[0216] The eighth field is used to indicate the forward error correction code.

[0217] Here, the content of the OAM frame can be referred to the aforementioned description, wherein the first field corresponds to the wavelength ID field in the OAM frame, the second field corresponds to the message field in the OAM frame, the third field corresponds to the frame header flag field in the OAM frame, the fourth field corresponds to the multiframe indicator field in the OAM frame, the fifth field corresponds to the frame length field in the OAM frame, the sixth field corresponds to the frame check code field in the OAM frame, the seventh field corresponds to the OCC field in the OAM frame, and the eighth field corresponds to the FEC field in the OAM frame.

[0218] In this embodiment, the second OAM information carries a service configuration message, which includes configuration information for the target wavelength and configuration information for the optical link. Specifically, the first field in the OAM frame carries the target wavelength configuration information, and the second field carries the optical link configuration information.

[0219] Specifically, the first field is the wavelength ID field, which is used to indicate the wavelength identifier of the target wavelength.

[0220] Specifically, the second field is a message field, which includes a configuration message that indicates the port information of each node in the optical link.

[0221] For example: Figure 1For example, the configuration message is used to indicate the information and port information of node A, node B, node C, and node Z. Further, optionally, the configuration message may also indicate that the target wavelength indicated by the wavelength ID is the wavelength used by each node in the configuration message.

[0222] Step 303: Determine the target wavelength used by the service based on the configuration information of the target wavelength, and determine the next node of the source node based on the configuration information of the optical link.

[0223] In this embodiment, the source node can determine the target wavelength used by the service based on the configuration information of the target wavelength, and can determine the next node of the source node based on the configuration information of the optical link.

[0224] For example: Figure 1 For example, the configuration information of the optical link is used to indicate the information and port information of node A, node B, node C, and node Z. Node A can determine the target wavelength used by the service based on the target wavelength configuration information, and can determine the next node as node B based on the optical link configuration information.

[0225] Step 304: Use the target wavelength to send the service signal of the service to the next node. The service signal carries the configuration information of the target wavelength and the configuration information of the optical link.

[0226] In this embodiment of the application, the source node sends a service signal to the next node in the following way:

[0227] 1) Load the service information of the service onto a carrier with the target wavelength to obtain a first signal;

[0228] 2) Load the second OAM information onto a carrier wave of a specific frequency to obtain a second signal;

[0229] 3) The second signal is applied to the first signal to obtain the service signal;

[0230] 4) Send the service signal to the next node.

[0231] The service signal obtained in the above manner carries the second OAM information. It is evident that the second OAM information is sent along with the service signal to the next node after the source node, so that the next node can use it to determine the target wavelength used by the service.

[0232] In the above technical solutions of this application embodiment, the interaction between the management platform and the nodes in the optical link is realized through the gateway. Although the description of the gateway is omitted in the above description, it should be understood that any interaction between the management platform and the nodes will be forwarded through the gateway.

[0233] In the technical solution of this application embodiment, when the source node transmits service signals to the destination node through intermediate nodes, the service signals also carry the configuration information of the target wavelength and the configuration information of the optical link. As a result, all nodes in the optical link realize the use of the target wavelength to transmit services, thereby improving the automation level of services.

[0234] Figure 4 This is a flowchart illustrating the configuration method for optical network services provided in the embodiments of this application. Figure 3 Applied to non-source nodes, such as Figure 4 As shown, the configuration method for the optical network service includes the following steps:

[0235] Step 401: Receive the service signal sent by the previous node of the non-source node, the service signal carrying the configuration information of the target wavelength and the configuration information of the optical link.

[0236] In this embodiment, the non-source node can be an intermediate node or a destination node in the optical link. The non-source node receives service signals sent by the previous node, and the service signals carry configuration information of the target wavelength and configuration information of the optical link.

[0237] Here, the service signal is obtained by loading a second signal onto a first signal, wherein the second signal is obtained by loading second OAM information onto a carrier of a specific frequency, and the first signal is obtained by loading service information onto a carrier having the target wavelength.

[0238] Here, the second OAM information is carried in an OAM frame, wherein the OAM frame includes:

[0239] The first field is used to indicate the wavelength identifier of the target wavelength;

[0240] The second field is used to indicate the port information of each node in the optical link.

[0241] Furthermore, the OAM frame also includes at least one of the following:

[0242] The third field is used to indicate the start position of the OAM frame;

[0243] The fourth field is used to indicate whether the OAM frame is a multiframe and its position within the multiframe;

[0244] The fifth field is used to indicate the length of the second field;

[0245] The sixth field is used to indicate the frame checksum;

[0246] The seventh field is used to indicate the optical communication channel;

[0247] The eighth field is used to indicate the forward error correction code.

[0248] Here, the content of the OAM frame can be referred to the aforementioned description, wherein the first field corresponds to the wavelength ID field in the OAM frame, the second field corresponds to the message field in the OAM frame, the third field corresponds to the frame header flag field in the OAM frame, the fourth field corresponds to the multiframe indicator field in the OAM frame, the fifth field corresponds to the frame length field in the OAM frame, the sixth field corresponds to the frame check code field in the OAM frame, the seventh field corresponds to the OCC field in the OAM frame, and the eighth field corresponds to the FEC field in the OAM frame.

[0249] In this embodiment, the second OAM information carries a service configuration message, which includes configuration information for the target wavelength and configuration information for the optical link. Specifically, the first field in the OAM frame carries the target wavelength configuration information, and the second field carries the optical link configuration information.

[0250] Specifically, the first field is the wavelength ID field, which is used to indicate the wavelength identifier of the target wavelength.

[0251] Specifically, the second field is a message field, which includes a configuration message that indicates the port information of each node in the optical link.

[0252] For example: Figure 1 For example, the configuration message is used to indicate the information and port information of node A, node B, node C, and node Z. Further, optionally, the configuration message may also indicate that the target wavelength indicated by the wavelength ID is the wavelength used by each node in the configuration message.

[0253] Step 402: Determine the target wavelength used by the service based on the configuration information of the target wavelength, and determine whether the non-source node is the destination node and / or the next node of the non-source node based on the configuration information of the optical link.

[0254] In this embodiment of the application, the non-source node can determine the target wavelength used by the service based on the configuration information of the target wavelength, and determine whether the non-source node is the destination node and / or the next node of the non-source node based on the configuration information of the optical link.

[0255] For example: Figure 1 For example, the configuration message indicates the information and port information of node A, node B, node C, and node Z. When node B is not the source node, node B can determine the target wavelength used for the service based on the target wavelength configuration information and determine node C as its next node based on the optical link configuration information. When node Z is not the source node, node Z can determine the target wavelength used for the service based on the target wavelength configuration information and determine its destination node based on the optical link configuration information.

[0256] In some alternative implementations, if the non-source node is not the destination node, the service signal is sent to the next node of the non-source node using the target wavelength.

[0257] In some alternative implementations, if the non-source node is the destination node, the wavelength of the reverse service of the optical link is determined based on the configuration information of the target wavelength. Here, the destination node can use the target wavelength as the wavelength of the reverse service.

[0258] In the technical solution of this application embodiment, when the source node transmits service signals to the destination node through intermediate nodes, the service signals also carry the configuration information of the target wavelength and the configuration information of the optical link. Thus, all nodes in the optical link realize the use of the target wavelength to transmit services, realize the end-to-end automatic forwarding of service signals based on the target wavelength and the automatic configuration of the reverse service wavelength, reduce the configuration workload of the management and control platform, and improve the degree of automation of services.

[0259] The technical solutions of the embodiments of this application are illustrated below with specific application examples.

[0260] Application Example 1

[0261] Reference Figure 5 , Figure 5 A flowchart of the configuration method for optical network services is provided, including the following steps:

[0262] 1) Node A sends a service request message to the management and control platform. The service request message is used to request the establishment of a service between Node A and Node Z.

[0263] 2) The control platform determines the optical link according to certain routing rules: Node A → Node B → Node C → Node Z.

[0264] 3) The management platform queries the wavelength usage of each node on the optical link, that is, the wavelengths used and / or unused by each node, and selects the target wavelength for the service based on the wavelength usage of each node.

[0265] Here, each node on the optical link sends OAM information. The management platform can use the OAM information to determine the wavelengths that the nodes have used and / or have not used, thereby determining the target wavelength that the optical link should select.

[0266] 4) The control platform sends OAM information to node A. The OAM information includes the configuration information of the target wavelength and the configuration information of the optical link.

[0267] Here, the target wavelength configuration information corresponds to the first field in the OAM frame, namely the wavelength ID field. The optical link configuration information corresponds to the second field in the OAM frame, namely the message field. The optical link configuration information may include information about node A and its port information, information about node B and its port information, information about node C and its port information, and information about node Z and its port information.

[0268] 5) Node A sends the service signal to Node B using the target wavelength based on the OAM information. The service signal also carries OAM information.

[0269] 6) Node B sends the service signal to Node C using the target wavelength based on the OAM information.

[0270] 7) Node C sends the service signal to Node Z using the target wavelength based on the OAM information.

[0271] 8) Node Z completes the reception of service signals.

[0272] 9) Node Z determines the wavelength of the reverse service as the target wavelength based on the OAM information and completes the wavelength configuration of the reverse service.

[0273] In the above process, the target wavelength is a direct-through wavelength on the optical link, meaning that every node on the optical link can use the target wavelength. When each node on the optical link sends a service signal to the next node, it carries the configuration information of the target wavelength and the configuration information of the optical link in the service signal. Thus, all nodes in the optical link can use the target wavelength to transmit services, realizing end-to-end automatic forwarding of service signals based on the target wavelength.

[0274] In the above process, since the receiving laser of the node is a broadband receiver and is not sensitive to wavelength, but the transmitting laser of the node requires a specific wavelength, the receiving port of node Z can directly read the wavelength configuration information in the OAM information from the received service signal, thereby automatically configuring the wavelength of the reverse service.

[0275] The technical solution of this application embodiment allows the management platform to determine the wavelength usage of each node in the optical link based on the OAM information of each node, thereby determining the target wavelength for direct optical link transmission. During service configuration from the source node to the destination node, the target wavelength is carried in the OAM information and sent to the source node. The source node and intermediate nodes also carry this OAM information when transmitting service signals, ensuring that all nodes in the optical link use the target wavelength for service transmission, achieving end-to-end automatic forwarding of service signals based on the target wavelength. This avoids wavelength conflicts in the optical link and eliminates the configuration time required for segment-by-segment confirmation of available wavelengths. Simultaneously, the destination node can directly read wavelength configuration information from the OAM information and configure the wavelength for reverse services directly based on this information, improving the configuration efficiency of reverse services.
