Description
Technical Field
The present invention relates to the field of optical transmission network technologies, and in particular, to a data processing method, apparatus, device, and storage medium.
Background
In the field of optical network transmission, a 100G optical module of an optical transmission network can be used for accessing an optical signal with a transmission rate less than 100G, and for data exceeding 100G, the access is prohibited. At present, the adopted solution is to use an optical module with a larger interface rate (e.g. 200G, 400G, etc.) to transmit over 100G data, or to adopt a mode of outputting a plurality of 100G optical modules in parallel to increase the transmission bandwidth of the optical module. However, in the second solution, the data between the optical modules needs to be aligned to restore the original signal, i.e. the signals of the optical modules need to be de-shifted. The commonly used deskew processing method is to detect the earliest and latest arriving data, obtain the offset, send the offset into a deskew circuit, fixedly select a certain path of read enable signal according to the packet binding condition, and judge whether to read according to the empty condition and the water level condition of each path of First Input First Output (FIFO) in the binding group. However, in higher-rate services, channels for transmitting signals are increased, and if the same processing method is adopted, situations such as increased logic resources, increased algorithm computation, and the like occur, and in the case of the number of channels being 2 to 12, numerous combinations are combined, so that more resources are required to guarantee logic implementation, and chip design is not facilitated.

Detailed Description
To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
In addition, in the embodiments of the present application, the words "optionally" or "exemplarily" are used for indicating as examples, illustrations or explanations. Any embodiment or design described as "optionally" or "exemplary" in embodiments of the invention is not to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the words "optionally" or "exemplarily" etc. is intended to present the relevant concepts in a concrete fashion.
Fig. 1 is a flowchart of a data processing method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
and S101, processing the control information of at least two channels.
In this embodiment, the at least two channels may be transmission channels of Optical Data Unit-Cn signals in an Optical Transport Network (OTN), where the ODUCn may be understood as an OTUCn (compensated Optical Transport Unit-Cn) signal with OTU overhead and a check portion removed.
The OTUCn signal is an OTN signal with a transmission rate exceeding 100Gbit/s, and can be split into n OTUC1 signals which can be supported and transmitted by a 100G optical module.
Further, the control information may be single-bit control information in the OTUCn data stream.
S102, caching data information of at least two channels.
It can be understood that the data stream includes control information and data information, that is, the data information in this step is data information in the OTUCn data stream except for the control information. The write indication information for caching the data information of the at least two channels may be valid information of data of each channel.
In addition, in the embodiment of the present application, the execution sequence of the step S101 and the step S102 is not limited, that is, the control information and the data information in the data stream may be processed simultaneously.
And S103, aligning and outputting the processed control information and the cached data information under the condition that the processed control information meets the preset condition.
In the embodiment of the present application, the control information may be separated from the data information, that is, the control information and the data information are processed separately. In this way, when the processed control information meets the preset condition, the processed control information and the cached data information can be aligned and output.
By adopting the method provided by the embodiment of the application, the defects that in the prior art, under the condition of multiple channels, control information and data information are aligned together, a large amount of data operation is generated, and excessive resources are occupied can be avoided. For example, in a 12-channel scenario of an ODUC12 service, or a scenario of any combination of channels 2 to 12, the solution provided by the embodiment of the present application may effectively avoid technical defects of solutions adopted in the prior art. And, under the condition that the number of channels is more, compared with the prior art, the solution provided by the embodiment of the application has more obvious advantages.
In an embodiment, the processing of the control information of the at least two channels in step S101 may include, but is not limited to, the following implementation manners.
For example, frame positioning overhead indication information of the control information in the at least two channels and a multiframe number of the multiframe positioning signal are obtained, and a channel where the frame positioning overhead indication information in the at least two channels arrives last is determined according to the frame positioning overhead indication information. And generating a read signal for caching the data information according to the data enable indication that the frame positioning overhead indication information in the at least two channels finally reaches the channel.
Exemplarily, the frame positioning overhead indication information of the control information and the multiframe number of the multiframe positioning signal in each channel may be determined based on a frame structure of the ODUC and an over 100G OTN standard, where a frame structure of the ODUC is shown in fig. 2, FA represents a frame header, and OUT OH represents a frame positioning overhead indication.
In addition, before the read signal of the data information is buffered, the read address of the buffered data information can be cleared.
In one embodiment, in the step S103, the preset condition may include, but is not limited to, the following examples.
For example, the frame positioning overhead indication information of the at least two channels satisfies a first condition, and meanwhile, the multiframe numbers of the multiframe positioning signals of the at least two channels satisfy a second condition.
The first condition may be that a time difference between arrival time of the frame positioning overhead indication information of the at least two channels at the respective channels is less than or equal to a preset deskew range, the deskew range may be set by a person skilled in the art according to actual needs, and the second condition may be that the multiframe numbers of the multiframe positioning signals of the at least two channels are the same.
That is, under the condition that the frame positioning overhead indication information of the at least two channels and the multiframe number of the multiframe positioning signal both meet the respective corresponding conditions, the processed control information and the cached data information are aligned and output, that is, the aligned OTUCn data streams of the at least two channels are read and output.
For example, the above-mentioned determination of whether the multiframe numbers of the multiframe positioning signals of the at least two channels are the same may be performed by using a matrix 90-degree orientation transformation algorithm.
Of course, when the frame positioning overhead indication information of the at least two channels does not satisfy the first condition, that is, the time difference between the frame positioning overhead indication information of the at least two channels and the respective channel reaches exceeds the preset depolarization range, the out-of-range alarm may be reported to other monitoring devices.
Similarly, under the condition that the multiframe numbers of the multiframe positioning signals of the at least two channels do not meet the second condition, that is, under the condition that the multiframe numbers of the multiframe positioning signals of the at least two channels are different, the alarm information can be reported to other monitoring equipment.
For the characteristic that an ODUC frame needs to align inter-channel data streams in a group according to a bound group, the processing method for separating control information and data information to align multiple channels provided in the embodiment of the present application can reduce resource occupation and reduce operation data amount under a multi-channel condition.
