Open Traffic Generator Models

Open Traffic Generator API defines a standard, model-driven and vendor-neutral interface for emulating layer 2-7 network devices and generating test traffic.

This repository is a collaborative effort and produces artifacts to offer a foundation for other tools and/or implementations that want to use a model first approach.

Ixia-c is a reference implementation of traffic generator described by these data models and API.

The focus of this repository is the following:

• a modeling guide outlining best practices
• a consistent set of OpenAPI vendor-neutral data and API models
• continuous build process that generates and validates artifacts
• a generated OpenAPI artifact

The models in this repo are under development and are subject to change, especially the models under the device node. All efforts will be made to keep them backwards compatible.

Setup

Please make sure that the client setup meets Python Prerequisites.

• Clone this project, cd inside it and make changes to spec following the modelling guide.

• Generate bundled spec called openapi.yaml inside artifacts/.

  python -m pip install -r requirements.txt
  python build.py
  

• To preview documentation and interact with schema, copy contents of openapi.yaml inside https://editor.swagger.io/.

• Upon pushing changes, artifacts/openapi.yaml and artifacts/otg.proto will be auto-generated and committed back to repository.

Python Prerequisites

• Please make sure you have python and pip installed on your system.

  You may have to use python3 or absolute path to python executable depending on Python Installation on system, instead of python.

  python -m pip --help
  

  Please see pip installation guide, if you don't see a help message.

• It is recommended that you use a python virtual environment for development.

  python -m pip install --upgrade virtualenv
  # create virtual environment inside `env/` and activate it.
  python -m virtualenv .env
  # on linux
  source .env/bin/activate
  # on windows
  .env\Scripts\activate on Windows
  

  NOTE: If you do not wish to activate virtual env, you use env/bin/python (or env\scripts\python on Windows) instead of python.
