Description

Data processing method, device, equipment and storage medium

Technical field

The present disclosure relates to the technical field of optical transmission networks.

Background technique

In the field of optical network transmission, the 100G optical module of the optical transmission network can be used to access optical signals with a transmission rate less than 100G, and for data exceeding 100G, it will be prohibited from passing. Currently, the adopted solution is to use optical modules with a larger interface rate (for example, 200G, 400G, etc.) to transmit data exceeding 100G, or to increase the transmission bandwidth of the optical module by using multiple 100G optical modules to output in parallel. However, the use of the above-mentioned second solution requires aligning the data between multiple optical modules to restore the original signal, that is, the signal of each optical module needs to be offset. The usual de-skew processing method is to detect the earliest and latest arriving data, get the offset and send it to the de-skew circuit, and select a certain channel of read enable signal according to the situation of packet binding. Determine whether to read according to the emptiness and water level of each channel in the binding group (First Input First Output, FIFO). However, in the case of higher-speed services, the channels for transmitting signals will also increase. If the same processing method is used, the logic resources will increase, the algorithm calculations will increase, etc., and the number of channels is 2-12. There are many downstream combinations, which require more resources to ensure logic implementation, which is not conducive to chip design.

Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

In addition, in the embodiments of the present application, words such as "optionally" or "exemplarily" are used to represent examples, illustrations, or illustrations. Any embodiment or design solution described as "optional" or "exemplary" in the embodiments of the present disclosure should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "optionally" or "exemplary" are used to present related concepts in a specific manner.

FIG. 1 is a flowchart of a data processing method provided by an embodiment of the application. As shown in FIG. 1, the method includes the following steps S101 to S103:

In S101, the control information of at least two channels is processed.

The at least two channels in the embodiment of this application can be the transmission channels of the ODUCn (Optical Data Unit-Cn) signal in the optical transport network (Optical Transport Network, OTN), where ODUCn can be understood as after removing the OTU overhead and check part OTUCn (completely standardized Optical Transport Unit-Cn) signal.

The OTUCn signal is an OTN signal with a transmission rate exceeding 100Gbit/s, which can be split into n OTUC1 signals that can be transmitted by a 100G optical module.

Further, the above-mentioned control information may be single-bit control information in the OTUCn data stream.

In S102, the data information of at least two channels is buffered.

It is understandable that the data stream includes control information and data information, that is, the data information in this step is data information other than the control information in the OTUCn data stream. The write instruction information (write signal) for buffering the data information of the at least two channels may be valid information (data valid signal) of the data of each channel.

In addition, in the embodiment of the present application, the sequence of performing step S101 and step S102 is not limited, that is, the control information and data information in the data stream can be processed at the same time.

In S103, when the processed control information satisfies the preset condition, the processed control information and the buffered data information are aligned and output.

In the embodiment of the present application, the control information and the data information can be separated, that is, the control information and the data information are processed separately. In this way, when the processed control information satisfies the preset condition, the processed control information and the buffered data information can be aligned and output.

By adopting the method provided by the embodiments of the present application, it is possible to avoid the defects that the control information and the data information are aligned together in the multi-channel situation in the related technology, which causes a large amount of data operation and takes up too much resources. For example, in the 12-channel scenario of the ODUC12 service, or the scenario of any combination of channel 2 to channel 12, the solution provided by the embodiment of the present application can effectively avoid the technical defects of the solution adopted by the related technology. Moreover, when the number of channels is larger, the advantages of the solution provided by the application example are more obvious.

In an embodiment, the process of processing control information of at least two channels in step S101 may include, but is not limited to, the following implementation manners.

For example, obtaining the frame positioning overhead indication information of the control information in at least two channels and the multi-frame alignment signal (Multi-frame Alignment Signal, MFAS) multi-frame number, and determining the frame positioning overhead in the at least two channels according to the frame positioning overhead indication information Indicates the channel where the message arrived last. According to the data enable indication that the frame positioning overhead indication information in the at least two channels finally arrives in the channel, a read signal for buffering the data information is generated.

Exemplarily, the frame positioning overhead indication information of the control information in each channel and the multi-frame number of the multi-frame positioning signal can be determined based on the frame structure of ODUC and the over 100G OTN standard. Among them, the frame structure of ODUC is shown in Figure 2. , FA means frame header, OUT OH means frame positioning overhead indication.

In addition, before the read signal of the aforementioned data information is cached, the read address of the cached data information may be cleared.

In an embodiment, in the foregoing step S103, the preset conditions may include but are not limited to the following examples.

For example, the preset condition is: the frame positioning overhead indication information of at least two channels meets the first condition, and/or the multiframe numbers of the multiframe positioning signals of at least two channels meet the second condition.

Wherein, the first condition may be that the time difference between the frame positioning overhead indication information of at least two channels to reach the respective channels is less than or equal to a preset debiasing range, which can be set by those skilled in the art according to actual needs; the second condition may be The multi-frame numbers of the multi-frame positioning signals for at least two channels are the same.

In some embodiments, when the frame positioning overhead indication information of the at least two channels and the multi-frame number of the multi-frame positioning signal both satisfy respective corresponding conditions, the processed control information and the buffered data information are aligned Output, that is, read and output aligned OTUCn data streams of at least two channels.

Exemplarily, the foregoing judging whether the multi-frame numbers of the multi-frame positioning signals of at least two channels are the same can be implemented by using a matrix 90-degree orientation transformation algorithm.

Of course, in the case where the frame positioning overhead indication information of at least two channels does not meet the first condition, that is, when the time difference between the frame positioning overhead indication information of at least two channels reaching the respective channels exceeds the preset de-biasing range, It can report out-of-range alarms to other monitoring equipment.

Similarly, when the multiframe numbers of the multiframe positioning signals of at least two channels do not meet the second condition, that is, when the multiframe numbers of the multiframe positioning signals of at least two channels are different, it is also possible Report alarm information to other monitoring equipment.

In view of the feature that ODUC frames need to align data streams between channels in a group according to the bound group, the processing method of separating control information and data information for multi-channel alignment proposed in the embodiment of this application can be used in multi-channel situations. , Reduce resource occupation and reduce the amount of computing data.
