* This component is the general PDU generated by the segmentation service to transmit a segment of a large message or file.
* It shall include the following components:
*
* @field version: contains the version number of this PDU definition. For this version of this data type it shall be equal to `1`.
*
* @field segmentationTime: contains information on when the message or file was segmented into 1 or several pieces.
*
* - not included in the present version @field segmentationLocation: is the location at which the message or file was segmented
*
* @field segmentContent : contains the segmented data of the message or file.

/**
* This component represents the payload of a segment/fragment of the file data.
* It is composed of the following fields:
* @field distributedAid: the ITS-AID of the file. The Psid/ Its-AID is a variable length INTEGER number.
* In the present version, the length of Its-AID will be less than or equal to 2 bytes.
*
* @field fileId: the id of the file to be distributed. It shall be set to the output of the SHA-256 hash function calculated on the transmitted CTL file content.
*
* @field fileDescription: optionally, the file description or metadata of the segmented file.
* For instance, metadata could contain parameters required when coding scheme using a FEC encoding is used (cf. IETF RFC 6726)
*
* @field messageSegmentTotalNumber: the total number of segments/fragments constituting the complete file.
*
* @field thisMessageSegmentNumber: the number that indicates the rank or position of this segment in the ordered sequence of segments constituting the complete CTL.
* The fields messageSegmentTotalNumber and thisMessageSegmentNumber may be present or absent depending on the use of a network/transport
* coding technique. If network/transport coding is used, these fields are unused and shall be absent.
* Note that coding technique is not specified in the current version of the standard.
*
* @field data: this field represents the file segment/fragment payload.
* MAX value is equal to the maximum size of the payload contained in the Segment PDU, i.e. the MTU-GN - control fields size. MTU value depends
* on the network access technology and on the network layer. For instance, if ITS-G5 access layer
* and GeoNetworking SHB protocol is used, MTU-GN - GN-Header - BTP-Header = 1428 bytes and MAX value is calculated as:
* 1428 - control fields size (30 bytes restricting the ITS-AID size to a maximum of 2 bytes).
*
* All segments of the original full CTL, except the last one, shall have the same size equal to MAX value.
* The Segmented CTL Responsemessage (SCRM) is a specific Segment PDU: it uses the parametrized data type SegmentedData where the psid parameter value is set to
* the ITS-AID value of the CTL service as specified in ETSI TS 102 965 (i.e. value 624)

# Editing this README
When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
## Suggestions for a good README
Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
## Name
Choose a self-explaining name for your project.
## Description
Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
## Badges
On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
## Visuals
Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
## Installation
Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
## Usage
Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
## Support
Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
## Roadmap
If you have ideas for releases in the future, it is a good idea to list them in the README.
## Contributing
State if you are open to contributions and what your requirements are for accepting them.
For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
The content of this repository and the files contained are released under the BSD-3-Clause license.
See the attached LICENSE file or visit https://forge.etsi.org/legal-matters.
You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
## Dependencies
## Authors and acknowledgment
Show your appreciation to those who have contributed to the project.
To compile the module, the following dependencies are required:
## License
For open source projects, say how it is licensed.
* The **[Ieee1609Dot2BaseTypes](https://forge.etsi.org/rep/ITS/asn1/ieee1609.2/)** module from the **IEEE Std 1609.2** - WAVE - Security Services for Applications and Management Messages
## Project status
If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.
