Overview

goSDN is also an application that will allow you to manage your multi-vendor network using one unified controller.

goSDN provides:

• Model driven device representation
• Native multi vendor support
• Multi controller environments

Concepts

The goSDN core - also called nucleus - is a lightweight library that manages principal network domains and provides southbound interface operations for orchestrated networking devices.

Principal Networking Domain (PND)

The PND is the single source of truth within a network. Its state is held and maintained by the controller. Any configuration of an OND has to be applied by the PND.

Orchestrated Networking Device (OND)

Any device directly configured by goSDN

Installing

You can install the latest release of goSDN locally using the go get command. Since the repository and some dependencies are not publicly available you have to modify your git config first:

> git config --global url."git@code.fbi.h-da.de:".insteadOf "https://code.fbi.h-da.de"
> go env -w GOPRIVATE=code.fbi.h-da.de/cocsn/*
> go get code.fbi.h-da.de/cocsn/gosdn/cmd/gosdn

To install the development version you need to clone the repo and use go install to build and install the binary:

# If you haven't cloned the repo yet
> git config --global url."git@code.fbi.h-da.de:".insteadOf "https://code.fbi.h-da.de"
> go env -w GOPRIVATE=code.fbi.h-da.de/cocsn/*
> cd $GOPATH/src
> git clone git@code.fbi.h-da.de:cocsn/gosdn.git

# checkout the develop branch (or any other branch)
> cd $GOPATH/src/code.fbi.h-da.de/cocsn/gosdn
> git checkout develop
> go install ./cmd/gosdn

Now you can start goSDN locally using the gosdn command or use the CLI to interact with a running goSDN instance.

Getting Started

k8s

We have an instance of goSDN for each the latest master and current develop branch running on the department's k8s cluster. These endpoints can be accessed using the gosdn cli command. If anything breaks please file an issue.

Using the CLI

The gosdn cli command allows you to interact with a running goSDN controller. Use gosdn help cli to print the available commands and flags.
