The present invention is described below with reference to preferred implementation steps, and fig. 1 is a flowchart of a data processing method for a flexible ethernet network according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S101, receiving a data stream of the flexible Ethernet through a data interface, wherein the data interface stores data stream parameters, and the data stream parameters are used for identifying the input specification and the output specification of the data stream;
step S102, coding a data stream according to an input specification of a data stream parameter to obtain a plurality of coding blocks with preset sizes, wherein the input specification corresponds to a coding mode of the data stream;
and step S103, storing the coding blocks into a target memory, and outputting output data of the coding blocks through the target memory, wherein the obtained output data conform to an output specification, and input and output specification parameters of the target memory are variable.
The steps receive the data flow of the flexible Ethernet through the data interface, select the corresponding coding mode according to the input specification of the data flow parameter, code the data flow, get multiple code blocks of the predetermined size; and according to the output specification of the data stream parameters, caching and outputting the plurality of coding blocks by using a target memory with variable input and output bit widths. By the mode, the purposes of processing and outputting data streams with different specifications according to the requirements of the receiving end are achieved, the technical effects of improving the reusability of the data interface and expanding the use scenes of the data interface are achieved, and the problems that the reusability of the data interface for processing data is poor and the scenes are limited due to the fact that the data interface of the flexible Ethernet in the related technology needs to consider different input and output transmission parameters and is specially designed when different levels are connected are solved.
The execution subject of the above steps may be flexible ethernet, or specifically, a data interface of flexible ethernet. The flexible ethernet and its data interface may be configured on a processor, a calculator or a controller for data processing to perform the data processing operations in the above steps, such as step S102 to step S103.
The flexible ethernet is disposed between the MAC layer and the PHY layer for signal data conversion between the MAC layer and the PHY layer. In the process from the MAC layer to the PHY layer, the data stream is converted into a physical pulse signal, otherwise referred to as a digital signal. The data unit is sent to the physical layer first, and data transmission is carried out through a virtual channel of the physical layer.
The transmission of the data stream between different layers needs to be adaptively converted. For example, the data format of the MAC layer and the data format of the PHY layer are different, and the data bit width of the data transmission is also different. This requires the flexible ethernet to provide a data interface to allow data conversion between different layers.
In the prior art, for the above situation, when the flexible ethernet creates the data interface, a dedicated data interface is created by writing according to different layers to which the data interface is docked and data formats of the different layers. Such data interfaces have poor reusability and limited use scenarios.
For this reason, the present embodiment provides a data processing method for flexible ethernet, which encodes and adjusts bit width of data according to requirements by integrating multiple encoders and using a target memory with variable input bit width and output bit width.
The data stream may be understood as a data stream format output by a data layer of the flexible ethernet interface. For example, in a scenario of a data flow from the MAC layer to the PHY layer, the data flow may be a data flow output by the MAC layer. In a PHY layer to MAC layer data flow scenario, the data flow may be a data flow output by the PHY layer.
It should be noted that, in some scenarios, a received next layer may also have a certain requirement on an input data format, so that a data stream output by an upper layer does not necessarily meet the requirement on data input by a next layer. A coordination sublayer may be provided to coordinate the data stream output from the previous layer to the data stream meeting the data requirement input from the next layer.
However, the processing of the above-mentioned coordination sublayer is completely different from the processing of the data interface, and cannot replace the data interface. For example, in the scenario of the data stream from the MAC layer to the PHY layer, the coordination sublayer RS is responsible for converting the data stream of the MAC into a format unrelated to the media interface, so that the data stream can be transmitted to the data interface for processing, and then transmitted to the PHY layer through the data interface.
The data flow parameters, that is, the attribute parameters of the data flow, may include an input specification of the data flow, for example, a data flow of a 10G ethernet network, or a data flow of a 100G ethernet network. The data stream parameters can be input by human beings, and can also be obtained by data extraction and identification.
According to the data stream parameters, the corresponding processing mode of the data stream can be determined, including how to encode, how large bit width is output, and the like. In this embodiment, in the flexible ethernet scenario, data conversion between the MAC layer and the PHY layer is performed to perform data encoding and bit width adjustment.
The data coding can determine a coding mode through data stream parameters, and code the data stream to obtain a plurality of coding blocks with preset sizes. And storing the plurality of coding blocks into a target memory, and outputting the corresponding bit width by the target memory. Thereby completing the conversion of the data interface to the data.
The target Memory may be a Memory with a variable input/output bit width.
Optionally, the encoding the data stream according to the input specification of the data stream parameter to obtain a plurality of encoded blocks with a preset size includes: acquiring an input specification of data stream parameters, wherein the input specification comprises target parameters, and the target parameters are used for determining a coding mode of the data stream; determining the coding mode of the data stream according to the value range of the value of the target parameter, wherein different value ranges of the target parameter correspond to different coding modes; and coding the data stream according to the determined coding mode to obtain a plurality of coding blocks with preset sizes.
As described above, the processing method corresponding to the data stream can be determined according to the target parameters in the data stream parameter input specification. For encoding, encoders for encoding data streams of different specifications are different. Therefore, a plurality of encoders can be integrated in the data interface, and the value range of each target parameter corresponds to one encoding mode, that is, the encoder corresponds to the data stream parameter.
And determining the coding mode of the data stream according to the value range of the value of the target parameter, and coding the data stream according to the determined coding mode to obtain a plurality of coding blocks with preset sizes.
Optionally, the target parameter of the data stream is fixed, and after determining the encoding mode of the data stream according to the value range of the value of the target parameter, the method further includes: selecting a corresponding encoder according to the determined encoding mode; the encoder is coupled, via a multiplexer, from a plurality of encoders to a data path of a data stream, wherein the data path is used for transmitting the data stream and the encoder is used for encoding the data stream.
The target parameters of the data stream usually do not change, and when the data stream is encoded, the encoder can be selected to encode the data stream according to the encoding mode corresponding to the parameters of the data stream, so as to obtain a plurality of encoding blocks of a preset size. In the case of encoding by an encoder, the encoder needs to be connected to the data path of the data stream in advance, so that the data stream can be encoded by transmitting the data stream to the encoder.
Optionally, storing the encoded block in a target memory, and outputting output data of the encoded block through the target memory includes: according to the data flow parameters, caching the coding blocks to a target memory, wherein the target memory is set to input the coding blocks meeting the input specification and output the coding blocks meeting the output specification; and reading and outputting the output data of the coding block from the target memory, wherein the output data conforms to the output specification.
The data stream parameters also include data stream parameters required by the output specification, i.e., the module to which the data stream flows. In the context of the MAC layer to PHY layer data interface, the output specification may be a parameter required for the PHY layer input. The output parameters mainly include bit width.
And storing the plurality of coding blocks output by the encoder into a target memory according to the output specification, and outputting the plurality of stored coding blocks according to the bit width required by the output specification by utilizing the variable performance of the input bit width and the output bit width of the target memory. And completing bit width adjustment of the coding blocks of the data stream. The stored plurality of coding blocks can also be output according to the frequency required by the output specification by utilizing the variable input frequency and output frequency performance of the target memory. Frequency adjustment for the encoded blocks of the data stream is completed.
Optionally, the target memory is a memory and is connected to the data stream path; the bit width and the frequency of the input and the output of the memory are variable; the input specification includes: input bit width and input frequency; the output specification includes an output encoding format, an output bit width, and an output frequency.
It should be noted that, a plurality of encoders are arranged in the data interface, and the number of the memory memories may be one or a small number of encoders, so that the encoders are connected with the memory memories through the multiplexer, when the corresponding encoders perform encoding, the encoders are communicated with the memory memories through the multiplexer, and a plurality of encoded blocks that have been encoded are input into the memory memories to perform bit width frequency adjustment. The memory can also output the coding block according to the output coding format in the output specification.
Optionally, after receiving the data stream of the flexible ethernet, the method further includes: receiving input specification parameters in response to a specification parameter input operation, wherein the specification parameters include at least one of: inputting bit width, inputting frequency, outputting coding format, outputting bit width and outputting frequency; the specification parameters are used as parameters of the input specification and/or the output specification.
Since the data stream itself can carry its own source and flow direction, the corresponding output specification can also be determined by the flow direction purpose carried by the data stream. The specification parameters may be input by a user to determine an input specification and an output specification of the data stream parameters.
And under the condition that the target memory is a memory, reading the coding block with the corresponding bit width from the memory according to the output parameter, outputting and outputting to the PHY layer.
Optionally, receiving the data stream of the flexible ethernet through the data interface includes: receiving a data stream sent by a media access control layer of the flexible Ethernet through an irrelevant media interface, wherein the data interface is the irrelevant media interface, and the media access control layer sends the data stream through the irrelevant media interface; and identifying a target field of the data stream, and determining data stream parameters of the data stream.
The above-mentioned receiving of the data stream of the flexible ethernet may be understood as a data stream that is received and sent to the data interface of the flexible ethernet by the coordination layer of the flexible ethernet. The coordination sublayer may convert the format and specification of the data stream to obtain a data stream that conforms to the input parameters. In the case of the MAC layer to the PHY layer in this embodiment, the coordination sublayer is responsible for converting the data stream of the MAC into the media independent interface format and transmitting the data stream to the PHY through the media independent interface. That is, the data stream transmitted by the media access control layer of the flexible ethernet is received through the unrelated media interface.
And identifying a target field of the data stream, and determining data stream parameters of the data stream. The data stream parameters are stored on the data stream itself, marked by the target field. By identifying the target field in the data stream, the position of the data stream parameters in the data stream can be determined, and the data stream parameters can be further extracted and determined.
The coordination sublayer may be configured according to actual situations. In some scenarios, the coordination layer may be provided before the data interface input, independent of the other layers, including the MAC layer or the PHY layer, and exist as a single sub-layer. In other scenarios, the coordination layer may also be in the MAC layer, or the PHY layer. The main consideration is the location of the data interface and the coordination layer, which needs to be in front of the data interface input.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than the order illustrated.
It should be noted that the present application also provides an alternative embodiment, which is described in detail below.
In the scenario of the FlexE Client flexible ethernet data Interface, the FlexE Client is a traditional Interface corresponding to the ethernet Network, and is an ethernet data stream based on the rate of the MAC layer (media access control layer) for interfacing UNIs (User Network interfaces) with different rates, which is generally generated by the following sources:
it may be generated internally by the system, such as a network processing unit NPU (embedded neural network processor), and the rate of the data stream is the rate of the determined Client MAC layer.
Data is sourced from a 10G/25G/40G/50G/100G/200G/400G PHY (PHY is a device that operates the OSI model physical layer one ethernet PHY layer may be a chip that can send and receive ethernet data frames (frames) which typically lack the advanced functionality of ake-on-LAN or Boot ROM provided by NIC (network interface controller) chips.
And a Client data interface from a Flexe Shim logic layer can also be used. The FlexE Shim is located between the MAC layer and the PHY layer, and is a core processing logic layer of FlexE. The method comprises the steps that a Flexe Client data stream of an MAC layer is mapped to a PHY layer of a Flexe Group for transmission; and also supports FlexE Client data streams that reflect data transmitted by the PHY layer within the FlexE Group to the MAC layer. FlexE Shim can bundle, subrate, channelize the bandwidth of the intra-group PHY layer based on the group.
The FlexE1.0 protocol specifies that the user data format that the time slots in FlexE Shim need to carry is a 66B code block encoded with 64B/66B, whereas the 10G/25G ethernet pair is encoded with four block types 0x2D, 0x33, 0x55, 0x66 more than 40G/100G ethernet. If a set of interfaces with different bit widths and different coding logics is reset for each Client, the setting process is very complicated and is not favorable for flexible switching.
In order to solve the above technical problem, in the present embodiment, an original implementation protocol is improved by setting a flexible interface for a FlexE Client (flexible ethernet Client) between a PCS (physical coding sublayer) and an MAC, so that the flexible interface can receive data transmitted by an MAC layer through unrelated media interfaces with different formats, receive data streams with different frequencies and different bit widths, and perform different coding for different Client clients, thereby improving the reusability and the realizability of the setting.
One Channel needs a flexible interface to bear one Client data stream, the size of the data stream can be 10G/25G/40G/50G/100G and the like, N Client data streams can be converted by the flexible interfaces of N channels, and 66B code blocks which accord with the Flexe data-bearing standard are output.
The data stream of each user is cached by a storage unit (Fifo/RAM), the output frequency and bit width of the Memory are specified through parameter setting, and each user data is divided into 5G/25G granularity required by Flexe and then output.
Fig. 2 is a schematic diagram of a flexible data interface provided according to an embodiment of the present application, and as shown in fig. 2, a flexible interface is provided at a PCS (physical coding sublayer) and a MAC interface, txc is transmission data, txd is a control signal, 64 is a transmission bit width specified by the unrelated medium interface, a is the number of used unrelated medium interfaces, e is a used clock frequency, 66 is a transmission bit width output by the interface, b is the number of used unrelated medium interfaces, and f is an output clock frequency.
The RS is a coordination sublayer and is responsible for converting a data stream of the MAC into a format of an unrelated medium Interface and transmitting the format of the unrelated medium Interface into the PHY through the unrelated medium Interface, the Flexe Interface module is a flexible FlexeClient Interface and consists of a coding module Decode, a multiplexer MUX and a Memory unit, the coding module is used for coding the data into a 66B code block, the multiplexer selects correct coded data according to parameters and outputs the coded data to the Memory, the Memory selects different input bit widths and output bit widths according to the parameters, and the parameters specifically relate to the formats of the different unrelated medium interfaces, the bit widths of the input data and the frequency used by the input data.
For example, if the parameter of a channel is 10G ethernet, the input data is transmitted through the XGMII interface, the input bit width is identified to be 32 bits, DDR (using clock double-edge delay) transmission is adopted, the encoded input data is output as 66-bit code blocks with 5G granularity, and if the parameter is 100G ethernet, the input data is identified to be transmitted through the CGMII interface, the input bit width is 64 bits, the clock rising edge transmission is adopted, the output is 20 66-bit code blocks with 5G granularity, and the definition of FlexE is to achieve decoupling of the MAC layer and the PHY layer, and data in different formats of unrelated medium interfaces need to be received.
The parameters can be manually defined and preset, and can also be obtained through hardware identification. For example, if a data stream of 10G ethernet is identified and XGMII interface is used, the parameters are the parameters corresponding to the 10G ethernet, and if preset, the identification process is not needed.
In the embodiment, a Memory (a Memory unit such as Fifo/RAM) with variable input and output bit widths and different coding logics are used for receiving data from different formats and converting the data into a 66B code block with granularity of 5G/25G required by Flexe Shim. And controlling the input and output bit width of the Memory and controlling the multiplexer to select proper coding logic by using the set parameters.
According to the embodiment, different data interfaces do not need to be arranged in the PHY layer according to different clients, and data streams with different frequencies and different bit widths can be received only by changing corresponding parameters and coded into the 66B code block carried by the Flexe time slot, so that a complex and repeated interface is avoided, and the reusability and the realizability of the data interface are improved.
