[0103] In this embodiment of the invention, the service tag information is located within the overhead area of ​​the OSU data stream.

[0104] The step of performing a packet operation on the OSU data stream includes: acquiring packet data in the OSU data stream; determining the next-hop routing information corresponding to the packet data based on the packet label information in the packet data, and updating the packet label information to obtain updated packet data; updating the service label information based on the next-hop routing information; and obtaining the processed OSU data stream based on the updated packet data and the updated service label information.

[0105] Packet label information includes at least one of the following: Media Access Control (MAC), Multiprotocol Label Switching (MPLS), Segmented Router (SR), and Internet Protocol address (IP).

[0106] Specifically, "updating the business label information" may include: reconfiguring TPN labels or other labels.

[0107] In this embodiment of the invention, performing a packet operation on the OSU data stream further includes: determining the OSU transmission time slot of the next hop based on the next hop routing information; the information processing method further includes: transmitting the processed OSU data stream according to the OSU transmission time slot of the next hop.

[0108] Specifically, "determining the OSU transmission time slot of the next hop based on the next hop routing information" may include: at the cross-connect layer, determining the OSU transmission time slot of the next hop based on the next hop routing information; the OSU transmission time slot may specifically include OSU and / or ODU time slots; but is not limited thereto;

[0109] The phrase "transmitting the processed OSU data stream according to the OSU transmission time slot of the next hop" may include: transmitting the processed OSU data stream at the cross-connect layer according to the OSU transmission time slot of the next hop; but it is not limited thereto.

[0110] In this embodiment of the invention, determining the next-hop routing information corresponding to the packet data based on the packet label information in the packet data, and updating the packet label information to obtain updated packet data includes: transmitting the packet data from the cross-connect layer to the packet processing layer; in the packet processing layer, determining the next-hop routing information corresponding to the packet data based on the packet label information in the packet data, and updating the packet label information to obtain updated packet data; updating the service label information based on the next-hop routing information; and obtaining the processed OSU data stream based on the updated packet data and the updated service label information includes: transmitting the next-hop routing information and the updated packet data from the packet processing layer to the cross-connect layer; updating the service label information based on the next-hop routing information in the cross-connect layer; and obtaining the processed OSU data stream based on the updated packet data and the updated service label information.

[0111] Furthermore, before determining the processing requirement information of the OSU data stream based on the service tag information of the optical service unit (OSU) data stream to be processed, the method further includes: obtaining the correspondence between the service tag information of the OSU data stream and the processing requirement information; the step of determining the processing requirement information of the OSU data stream based on the service tag information of the optical service unit (OSU) data stream to be processed includes: determining the processing requirement information of the OSU data stream based on the correspondence and the service tag information of the OSU data stream to be processed.

[0112] In this embodiment of the invention, the information processing method further includes: performing an interleaving operation on the OSU data stream when the processing requirement information indicates that the OSU data stream does not need to be grouped.

[0113] Regarding crossover operations, they can specifically include OSU and / or ODU crossovers; however, they are not limited to this.

[0114] The following is an example of the information processing method provided in the embodiments of the present invention. The information processing device corresponds to the following OSU / OTN (representing OSU or OTN supporting OSU) system.

[0115] To address the aforementioned technical problems, embodiments of the present invention provide an information processing method, specifically a method for an OSU / OTN system to support Layer 2 switching (i.e., packet switching) and Layer 3 routing (i.e., packet routing) functions, enabling the OSU / OTN system to possess Layer 2 switching and Layer 3 routing capabilities. Specifically, a packet processing module can be added to the OSU / OTN system, and: the need for packet processing is determined by the TPN label or other labels (corresponding to the aforementioned service label information) in the overhead of the OSU data stream; if packet processing is required, the OSU frame (i.e., the OSU data stream, also known as the OSU service) is sent to the packet processing module for Layer 2 switching or Layer 3 routing processing; if packet processing is not required, the OSU frame undergoes Layer 1 OTN (including ODU) and / or OSU processing (corresponding to the aforementioned crossover operation).

[0116] In this embodiment of the invention, a packet processing module is added to the OSU / OTN system, such as... Figure 3 As shown. Specifically, identification information can be defined in the TPN tag or other tags of the OSU frame to determine whether to perform packet processing; the frame structure is as follows. Figure 5 As shown. Figure 3 The OSU (OTN) data stream in the text can be understood as the OSU (or OTN that supports OSU) data stream; ODU stands for Optical Data Unit.

[0117] The specific solutions provided in the embodiments of the present invention are as follows: Figure 4 As shown, it includes:

[0118] Step 41: The management control plane in the OSU / OTN system assigns TPN tags or other tags to the service;

[0119] In other words, confirm the correspondence between business and business tag information in advance.

[0120] Step 42: OSU (or OTN that supports OSU) services enter the OSU (or OTN that supports OSU) device.

[0121] Step 43: The forwarding plane in the OSU / OTN system reads the TPN tag or other tags in the OSU frame.

[0122] Specifically, the forwarding plane sends a request to the management control plane based on the OSU (or OTN that supports OSU) service; the management control plane responds with the TPN tag or other tags for the service based on the request.

[0123] Step 44: The forwarding plane determines whether the OSU service needs to be processed in groups based on the TPN label or other labels (corresponding to the above determination of the processing requirements of the OSU data stream based on the service label information of the OSU data stream to be processed); if yes, that is, group processing is required, then proceed to step 45; if no, that is, group processing is not required, then proceed to step 48.

[0124] Step 45: Open the OSU frame and extract the packet data from the frame. The packet data enters the packet processing module from the first-layer optical data unit ODU / OSU module (i.e., ODU and / or OSU cross-connect module). Corresponding to the above-described acquisition of packet data in the OSU data stream; the packet data is then transmitted from the cross-connect layer to the packet processing layer.

[0125] Step 46: The packet processing module processes packet data based on at least one of the following labels (i.e., packet labels): Media Access Control (MAC), Multiprotocol Label Switching (MPLS), Segmented Routing (SR), and Internet Protocol Address (IP). This determines the next-hop routing information for the packet data and updates the configuration of at least one of the MAC, MPLS, SR, and IP labels. Corresponding to the above, at the packet processing layer, based on the packet label information in the packet data, the next-hop routing information corresponding to the packet data is determined, and the packet label information is updated to obtain the updated packet data.

[0126] Specifically, for at least one of the labels such as MAC, MPLS, SR, and IP, routing and label replacement are performed according to the packet data processing protocol (i.e., determining the next-hop routing information and updating the configuration).

[0127] Step 47: Packet data enters the first-layer ODU / OSU module from the packet processing module. Based on the next-hop routing information, the next-hop OSU / ODU (representing OSU and / or ODU) time slot is determined (corresponding to the OSU transmission time slot mentioned above), and TPN labels or other labels (corresponding to the service label information mentioned above) are configured. Corresponding to the above, the next-hop routing information and the updated packet data are transmitted from the packet processing layer to the cross-connect layer. At the cross-connect layer, based on the next-hop routing information, the next-hop OSU transmission time slot is determined, and the service label information is updated. Based on the updated packet data and the updated service label information, the processed OSU data stream is obtained.

[0128] The processed OSU data stream can then be transmitted according to the OSU transmission time slot of the next hop.

[0129] There is a correspondence between the next-hop routing information and the OSU / ODU timeslot of the next hop, as well as the TPN label or other labels.

[0130] Step 48: OSU frames are interleaved within a single ODU / OSU module. This corresponds to the interleaving operation performed on the OSU data stream when the processing requirement information indicates that the OSU data stream does not require packet processing.

[0131] Step 49: OSU (or OTN supporting OSU) service output from OSU (or OTN supporting OSU) device. This corresponds to transmitting the processed OSU data stream described above.

[0132] As can be seen from the above, the solution provided by the embodiments of the present invention relates to: a method for an OSU / OTN system to support Layer 2 switching and Layer 3 routing functions, which enables the OSU / OTN system to have Layer 2 switching and Layer 3 routing functions by adding a packet processing module to the OSU / OTN system. Specifically:

[0133] Whether grouping is required is determined by the TPN label or other labels in the OSU overhead.

[0134] If packet processing is required, an OSU frame is opened, and the packet data within the frame is extracted. The packet data enters the (Layer 2 and / or Layer 3) packet processing module from the Layer 1 ODU / OSU module. The packet processing module processes the packet data based on at least one of the following labels: MAC, MPLS, SR, and IP, determines the next-hop routing information, and updates the configuration of at least one of the MAC, MPLS, SR, and IP labels. The packet data then enters the Layer 1 ODU / OSU module. Based on the next-hop routing information, the next-hop OSU / ODU timeslot is determined, and the TPN label or other labels are configured.

[0135] If no packet processing is required, the OSU frame will undergo one layer of ODU / OSU processing.

[0136] In summary, the solution provided by the embodiments of the present invention enables OSU / OTN devices to have Layer 2 switching and Layer 3 routing functions, thus possessing stronger capabilities.

[0137] This invention also provides an information processing device, such as... Figure 6 As shown, it includes:

[0140] The service tag information includes: branch port number TPN tag information, or other tag information other than the TPN tag information;

This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

These hardware circuits include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors such as logic chips and transistors, or other discrete components. Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.

[0171] The above describes the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
