[0128] The phrase "at least two OSU data streams to be processed" can refer to data received within a preset time period or data received in the same session; no specific limitation is made here.

[0129] The processing priority information corresponding to the OSU data stream can also be understood as the priority of OSU services.

[0130] The information processing method provided in this embodiment of the invention sends the service priority information corresponding to at least two Optical Service Unit (OSU) data streams to be processed to a management control plane device; receives the tag information corresponding to the at least two OSU data streams fed back by the management control plane device; determines the processing priority information corresponding to the at least two OSU data streams based on the tag information; and performs processing operations on the at least two OSU data streams based on the processing priority information.

This method enables fast, convenient, and accurate processing of OSU services based on service priority, simplifying operations, improving processing accuracy, and effectively solving the problems of complex and inaccurate operation in existing information processing schemes for OSU services.

[0131] In this embodiment of the invention, the step of performing processing operations on the at least two OSU data streams according to the processing priority information corresponding to the at least two OSU data streams respectively includes: allocating first information to each of the at least two OSU data streams in sequence according to the processing priority information corresponding to the at least two OSU data streams respectively; mapping each of the OSU data streams according to the first information; wherein the first information includes at least one of mapping method, time slot and bandwidth.

[0132] Regarding "mapping each of the OSU data streams", it may include: mapping each of the OSU data streams using a preset algorithm.

[0133] Specifically, the step of allocating first information to each of the at least two OSU data streams in sequence according to the processing priority information corresponding to each OSU data stream includes: for OSU data streams corresponding to the same processing priority information, allocating first information to the first OSU data stream in chronological order according to the time information of receiving the OSU data stream; and / or, for OSU data streams corresponding to different processing priority information, allocating first information to the second OSU data stream in chronological order according to the processing priority; wherein, the first OSU data stream is the OSU data stream corresponding to the same processing priority information; and the second OSU data stream is the OSU data stream corresponding to different processing priority information.

[0134] The order of time can be the order of events in time, and the order of processing priorities can be the order of processing priorities from high to low, but it is not limited to these.

[0135] In this embodiment of the invention, the step of performing processing operations on the at least two OSU data streams according to the processing priority information corresponding to the at least two OSU data streams may include: processing the GCC channel information corresponding to each OSU data stream in sequence according to the processing priority information corresponding to the at least two OSU data streams.

[0137] The order of time can be the order of events in time, and the order of processing priorities can be the order of processing priorities from high to low, but it is not limited to these.

[0138] Furthermore, before processing the GCC channel information corresponding to each OSU data stream in sequence according to the processing priority information corresponding to the at least two OSU data streams, the method further includes setting an indicator field for the GCC channel information in the OSU layer of the forwarding plane device.

[0139] In this embodiment of the invention, the indication field may be located in the overhead area of ​​the OSU layer.

[0140] In this embodiment of the invention, sending the service priority information corresponding to the at least two Optical Service Unit (OSU) data streams to be processed to the management control plane device includes: determining the service priority information corresponding to the at least two OSU data streams to be processed; sending tag request information to the management control plane device; the tag request information carrying the service priority information corresponding to the at least two OSU data streams; and receiving the tag information corresponding to the at least two OSU data streams fed back by the management control plane device, including: receiving the tag response information fed back by the management control plane device based on the tag request information; and identifying the tag information corresponding to the at least two OSU data streams in the tag response information.

[0141] The service priority information carried in the tag request information may specifically be: the identifier of the OSU data stream and the corresponding service priority information; however, no specific limitation is made here.

[0142] This invention also provides an information processing method applied to management and control plane devices, such as... Figure 3 As shown, it includes:

[0143] Step 31: Receive the service priority information corresponding to at least two Optical Service Unit (OSU) data streams to be processed from the forwarding plane device;

[0144] Step 32: Based on the service priority information corresponding to the at least two OSU data streams, feed back the tag information corresponding to the at least two OSU data streams to the forwarding plane device; wherein, the tag information is the branch port number TPN tag information, or other tag information besides the TPN tag information.

[0145] The phrase "at least two OSU data streams to be processed" can refer to data received within a preset time period or data received in the same session; no specific limitation is made here.

[0146] The information processing method provided in this embodiment of the invention receives service priority information corresponding to at least two Optical Service Unit (OSU) data streams to be processed from a forwarding plane device; based on the service priority information corresponding to the at least two OSU data streams, it feeds back tag information corresponding to the at least two OSU data streams to the forwarding plane device; wherein the tag information is Branch Port Number (TPN) tag information, or other tag information besides the TPN tag information; it can support fast, convenient, and accurate processing of OSU services according to service priority, simplifying operation, improving processing accuracy, and effectively solving the problems of complex and inaccurate operation of information processing schemes for OSU services in the prior art.

[0147] In this embodiment of the invention, the receiving and forwarding plane device sends service priority information corresponding to at least two Optical Service Unit (OSU) data streams to be processed, respectively, which includes: receiving and forwarding plane device sending tag request information; the tag request information carries service priority information corresponding to the at least two OSU data streams, respectively; the step of feeding back tag information corresponding to the at least two OSU data streams to the forwarding plane device according to the service priority information corresponding to the at least two OSU data streams, respectively, includes: feeding back tag response information to the forwarding plane device according to the tag request information; the tag response information carries tag information corresponding to the at least two OSU data streams, respectively.

[0148] The service priority information carried in the tag request information may specifically be: the identifier of the OSU data stream and the corresponding service priority information; however, no specific limitation is made here.

[0149] Furthermore, before feeding back the tag information corresponding to the at least two OSU data streams to the forwarding plane device based on the service priority information corresponding to the at least two OSU data streams respectively, the method further includes: obtaining the correspondence between service priority information and tag information; the step of feeding back the tag information corresponding to the at least two OSU data streams to the forwarding plane device based on the service priority information corresponding to the at least two OSU data streams respectively includes: feeding back the tag information corresponding to the at least two OSU data streams to the forwarding plane device based on the correspondence and the service priority information corresponding to the at least two OSU data streams respectively.

[0150] Regarding "obtaining the correspondence between business priority information and tag information", it could be: establishing a correspondence between business priority information and tag information.

[0151] The following is an example of the information processing method provided in the embodiments of the present invention. The forwarding plane device is hereinafter referred to as the forwarding plane, and the management and control plane device is hereinafter referred to as the management and control plane; the first information includes the mapping method and time slot as an example.

[0152] To address the aforementioned technical issues, and considering that: 1) current OTN devices supporting the OSU mechanism cannot classify and map services based on priority; 2) the OSU layer lacks a GCC channel and a service-priority-based GCC channel processing mechanism. Specifically, the OTU and ODU layers currently have General Communication Channels (GCC), but the OSU layer lacks a GCC channel, thus preventing the transmission of GCC channel information; this invention provides an information processing method, specifically a method for mapping and configuring services according to priority and processing GCC in an OSU system; the data flow processing flow of this solution can be found in [reference needed]. Figure 4 Specific details involved Figure 5 and Figure 7 The two-part scheme is shown below:

[0153] Part 1 Figure 5 The proposed solution may specifically include the following steps ( Figure 5 The diagram shown can also be understood as the overall process of OSU mapping and time slot configuration scheme based on service priority:

[0154] Step 51: Establish a business priority lookup table in the management control plane (corresponding to the above correspondence); that is, establish a business priority lookup table in the management control plane (the business priority lookup table can specifically be a lookup table containing the correspondence between business priorities and tag information), such as... Figure 4 As shown, Figure 4The above can also be interpreted as representing the intent of establishing a business priority lookup; Figure 4 In this context, ODU stands for Optical Data Unit, and OTU stands for Optical Transmission Unit. Figure 4 The diagram can also be understood as the OTU (or the OSU within the OTU) data flow processing flow.

[0155] Step 52: Assign TPN tags or other tags according to business priority;

[0156] Specifically, the forwarding plane sends a request carrying service priority to the management and control plane (corresponding to the above-mentioned sending tag request information to the management and control plane device; the tag request information carries the service priority information corresponding to the at least two OSU data streams respectively);

[0157] The management control plane assigns TPN tags or other tags according to the business priority based on the table in step 51. For example, the larger the TPN value, the higher the business priority; or, the smaller the TPN value, the higher the business priority; or, the larger the value of other tags, the higher the business priority; or, the smaller the value of other tags, the higher the business priority.

[0158] The management control plane sends information carrying tags to the forwarding plane (corresponding to the above-mentioned tag response information fed back to the forwarding plane device according to the tag request information; the tag response information carries the tag information corresponding to the at least two OSU data streams respectively).

[0159] Step 53: Read TPN tags or other tags from the forwarding plane;

[0160] That is, the forwarding plane identifies the tag from the received information; corresponding to the tag information identified above in the tag response information, which corresponds to the tag information of the at least two OSU data streams respectively.

[0161] Step 54: The forwarding plane determines whether the OSU services have the same priority based on the TPN label or other labels (corresponding to the above determination of the processing priority information corresponding to the at least two OSU data streams based on the label information corresponding to the at least two OSU data streams respectively); if not, proceed to step 55; if yes, proceed to step 57.

[0162] The priority of OSU services corresponds to the processing priority information mentioned above.

[0163] Step 55: Allocate mappings and time slots according to priority level from high to low (this may also include bandwidth allocation); Proceed to Step 56;

[0164] That is, if they are not of the same priority, the mapping and time slots (and may also include bandwidth allocation) are allocated from high to low priority; corresponding to the OSU data streams with different processing priority information, the mapping method and time slots are allocated to the second OSU data streams according to the processing priority order; the second OSU data streams are OSU data streams with different processing priority information.

[0165] Step 56: Map according to GMP, GFP, or other algorithms;

[0166] Step 57: Assign mappings and time slots according to arrival time (this may also include bandwidth allocation);

[0167] That is, if they have the same priority, the mapping and time slots are allocated according to the order of arrival time (and may also include bandwidth allocation); corresponding to the OSU data streams with the same processing priority information, the mapping method and time slots are allocated to the first OSU data stream in chronological order according to the time information of the received OSU data streams; the first OSU data stream is the OSU data stream with the same processing priority information.

[0168] Step 58: Map according to the general mapping process GMP or the general framing process GFP or other algorithms.

[0169] Part Two, in this embodiment of the invention, the OSU layer can define GCC channels, and the specific GCC channels of the OSU can be included in the OSU overhead, such as... Figure 6 As shown. This corresponds to the indication field for setting GCC channel information in the OSU layer of the forwarding plane device as described above; specifically, the indication field can be located in the overhead area of ​​the OSU layer.

[0170] Figure 7 The proposed solution may specifically include the following steps ( Figure 7 The diagram shown can also be understood as the overall process of OSU's GCC processing scheme based on business priority:

[0171] Step 71: The management control plane establishes a business priority lookup table (corresponding to the above correspondence);

[0172] That is, a business priority lookup table is established in the management control plane (the business priority lookup table can specifically be a lookup table containing the correspondence between business priorities and tag information), such as Figure 4 As shown, Figure 4 The above can also be interpreted as representing the intent of establishing a business priority lookup; Figure 4 In this context, ODU stands for Optical Data Unit, and OTU stands for Optical Transmission Unit. Figure 4 The diagram can also be understood as the OTU (or the OSU within the OTU) data flow processing flow.

[0173] Step 72: Assign TPN tags or other tags according to business priority;

[0174] Specifically, the forwarding plane sends a request carrying service priority to the management and control plane (corresponding to the above-mentioned sending tag request information to the management and control plane device; the tag request information carries the service priority information corresponding to the at least two OSU data streams respectively);

[0175] The management control plane assigns TPN tags or other tags according to the business priority based on the table in step 71. For example, the larger the TPN value, the higher the business priority; or, the smaller the TPN value, the higher the business priority; or, the larger the value of other tags, the higher the business priority; or, the smaller the value of other tags, the higher the business priority.

[0176] The management control plane sends information carrying tags to the forwarding plane (corresponding to the above-mentioned tag response information fed back to the forwarding plane device according to the tag request information; the tag response information carries the tag information corresponding to the at least two OSU data streams respectively).

[0177] Step 73: Read TPN tags or other tags from the forwarding plane;

[0178] That is, the forwarding plane identifies the tag from the received information; corresponding to the tag information identified above in the tag response information, which corresponds to the tag information of the at least two OSU data streams respectively.

[0179] Step 74: The forwarding plane determines whether the OSU services have the same priority based on the TPN label or other labels (corresponding to the above determination of the processing priority information corresponding to the at least two OSU data streams based on the label information corresponding to the at least two OSU data streams respectively); if no, proceed to step 75; if yes, proceed to step 76.

[0180] The priority of OSU services corresponds to the processing priority information mentioned above.

[0181] Step 75: Process GCC channel content (corresponding to GCC channel information) according to priority level;

[0182] That is, if they are not of the same priority, the GCC is processed from high to low priority; corresponding to the OSU data streams with different processing priority information, the second GCC channel information is processed in order of processing priority; the second GCC channel information is the GCC channel information corresponding to the OSU data streams with different processing priority information.

[0183] Step 76: Process GCC channel content according to arrival time;

[0184] That is, if they have the same priority, the GCCs are processed according to their arrival time; corresponding to the OSU data streams with the same processing priority information, the first GCC channel information is processed in chronological order according to the time information of the received OSU data streams; the first GCC channel information is the GCC channel information corresponding to the OSU data streams with the same processing priority information.

[0185] As can be seen from the above, the solutions provided by the embodiments of the present invention involve:

[0186] (1) In OTN devices that support the OSU mechanism, configure the TPN tag or other tags in the OSU overhead according to the OSU service level.

[0187] (2) Mapping and cross-referencing are performed according to the priority of OSU services.

[0188] (3) Define the GCC channel of the OSU layer. Process the information in the GCC channel of the OSU according to the priority of the service.

[0189] In summary, this solution provides a service priority processing system for OSU services, enabling the OSU mechanism to have QoS (Quality of Service) and slicing capabilities, as well as GCC channels; it effectively solves the problems of complex and inaccurate operation of existing information processing solutions for OSU services.
