Embodiment 1

[0063] image 3 It is a flowchart of the TLV message parsing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of parsing TLV messages, especially hardware parsing TLV messages. The method can be executed by a TLV message parsing device. Such as image 3 As shown, the method specifically includes the following steps:

[0064] Step 310, using the preset multi-stage pipeline structure to analyze each TLV field in the current shot data entering the multi-stage pipeline structure step by step, wherein each stage of the pipeline parses a TLV field to obtain the processing action information of the TLV field, The front-stage pipeline becomes idle after parsing the TLV field, so as to parse the data containing the packet header in the next shot entering the multi-stage pipeline structure.

[0065] Among them, the multi-stage pipeline structure is implemented based on hardware, such as ASIC or FPGA. The number of pipeline stage...

Embodiment 2

[0084] On the basis of the above embodiments, this embodiment provides a specific implementation process of parsing the TLV field by a single-stage pipeline, and each stage of the pipeline in a multi-stage pipeline structure performs the same operation. Figure 4 It is a flow chart of single-stage pipeline parsing TLV fields in the TLV message parsing method provided by Embodiment 2 of the present invention, as Figure 4 shown, including:

[0085] Step 410, for the current stage of the pipeline, analyze the current TLV field to obtain the type of the current TLV field and the starting position of the next TLV field.

[0086] Wherein, Type and Length in the TLV field are both fixed lengths. From the starting position of the TLV field, read the first fixed length (for example, 2 bytes) to read the Type, and continue to read the second fixed length (for example, 1 byte). byte) that is, the Length is read, and then the Value is read according to the read Length value (for example...

Embodiment 3

[0097] On the basis of each of the above-mentioned embodiments, considering that the bit width of the data bus is fixed (such as 128bit or 256bit, etc.), the length of the TLV message may exceed the bit width of the data bus. At this time, the TLV message is split into multiple beats Data is transmitted and parsed. This embodiment provides a process of splitting the transmission and parsing the TLV message level by level under the above circumstances. Explanations of terms and steps that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment.

[0098] If the length of the TLV message exceeds the bit width of the data bus, the TLV message is split into at least two beats of data according to the bit width of the data bus, and the at least two beats of data are sequentially entered into a multi-stage pipeline structure for step-by-step analysis. Wherein, the longest length of each shot of data is the bit width of the data ...

Abstract

The invention discloses a TLV (Type Length Value) message parsing method and device, electronic equipment, and a storage medium. The method comprises the following steps: using a preset multilevel pipeline structure to parse each TLV field in current beat data entering the structure step by step, wherein each level of the pipeline parses one TLV field to obtain processing action information of theTLV field, the front level of the pipeline parses the TLV field and then becomes free, so as to parse next beat data including a message header; outputting current beat data and the processing actioninformation of each TLV field synchronously by the last level of pipeline in the structure; and determining a final processing action of a TLV message involved in the current beat data according to the processing action information of each TLV field. The TLV message parsing method provided by the invention performs TLV message parsing based on the multilevel pipeline structure; each level of thepipeline parses one TLV field, and releases the pipeline space in time after parsing; and the multilevel pipeline structure can process a plurality of TLV messages synchronously, so as to realize thehigh bandwidth processing of the TLV message.

Description

technical field [0001] Embodiments of the present invention relate to message parsing technologies, and in particular, relate to a TLV message parsing method, device, electronic equipment, and storage medium. Background technique [0002] TLV (Type Length Value) is a format in network packets. The purpose of the TLV format is to transmit one or more fields of variable length. Among them, Type specifies the type of TLV, Length indicates the length of the data part of the TLV, and Value is the data part. Such as figure 1 As shown, multiple TLVs can be connected in series to form a TLV message. figure 2 It is a specific example of the TLV message, and the TLV message is composed of 4 TLV fields. The typical application of TLV in the network is the Option field in the IP (Internet Protocol, protocol for interconnection between networks) message header and the Option field in the TCP (Transmission Control Protocol, transmission control protocol) message header. [0003] Each...
