# Requisites
|
|
|
|
The guides and walkthroughs below make some reasonable assumptions to simplify the deployment of the TFS controller, the execution of experiments and tests, and the development of new contributions.
|
|
|
|
In particular, we assume:
|
|
|
|
|
|
|
|
- A physical server or virtual machine for running the TFS controller with the following minimum specifications (check section [Configure your Machine](./1.-Deployment-Guide/1.1.-Configure-your-Machine) for additional details):
|
|
|
|
- 4 cores / vCPUs
|
|
|
|
- 8 GB of RAM (10 GB of RAM if you want to develop)
|
|
|
|
- 60 GB of disk (100 GB of disk if you want to develop)
|
|
|
|
- 1 NIC card
|
|
|
|
- [VSCode](https://code.visualstudio.com/) with the [Remote SSH](https://code.visualstudio.com/docs/remote/ssh) extension
|
|
|
|
- Working machine software:
|
|
|
|
- [Ubuntu Server 22.04.4 LTS](https://releases.ubuntu.com/22.04/) or [Ubuntu Server 20.04.6 LTS](https://releases.ubuntu.com/20.04/)
|
|
|
|
- [MicroK8s v1.24.17](https://microk8s.io/)

# Versions
|
|
|
|
|
|
|
|
New versions of TeraFlowSDN are periodically released.
|
|
|
|
Each release is properly tagged and a branch is kept for its future bug fixing, if needed.
|
|
|
|
|
|
|
|
- The branch *master*, points always to the latest stable version of the TeraFlowSDN controller.
|
|
|
|
- The branches *release/X.Y.Z*, point to the code for the different release versions indicated in branch name.
|
|
|
|
- Code in these branches can be considered stable, and no new features are planned.
|
|
|
|
- In case of bugs, point releases increasing revision number (Z) might be created.
|
|
|
|
- The main development branch is named as *develop*.
|
|
|
|
- **Use with care! Might not be stable.**
|
|
|
|
- The latest developments and contributions are added to this branch for testing and validation before reaching a release.
|
|
|
|
|
|
|
|
To choose the appropriate branch, follow the steps described in [1.3. Deploy TeraFlowSDN > Checkout the Appropriate Git Branch](/1.-Deployment-Guide/1.3.-Deploy-TeraFlowSDN#checkout-the-appropriate-git-branch)
