September 1st is traditionally the day that kicks off the new “apprenticeship season” in Germany. It is the time when people, who are eager to learn a trade, are starting their new path.

This year we are happy to be able to provide this path to two new faces in our STORDIS Team:

Yeliz Yalbirdak and Anthony Omegbolu are joining us as apprentices (or “Azubis” as we say in Germany) training to become “Merchants in wholesale and foreign trade”. Both of them will be going through all of our departments and get to know the ins and outs of the different departments and get some real hands-on experience by doing so.

We are proud to be able to call you a part of the STORDIS Team and are looking forward to seeing your progress!

How are you feeling after the first month and have you settled in already?
Are you already looking forward to working in a certain department?

I am feeling really well. The team and the atmosphere are great. I am especially curious to see the management department, as well as the sales department.

Yeliz Yalbirdak

I’ve settled in really well. There is always something to do and the team is great. Every department has its ups and downs and I am looking forward to go through all of the departments.

We are pleased to announce that we have signed a distribution agreement with BISDN.

This step allows us to extend our Network Operating System (NOS) portfolio with the free and open source BISDN Linux. The NOS itself is developed in Berlin by BISDN, a company focussing on whitebox switching and open networking solutions.

The latest BISDN Linux release 4.0 is based on the open embedded Yocto Dunfell Linux distribution and runs a mainline 5.10 kernel. Utilizing the Linux network stack, it can be configured with all the standard and well-known Linux tools. Therefore, it integrates seamlessly in any existing datacentre environment and plays well with all the network automation routines usually utilised just for servers.

STORDIS now offers #Open2Support SLA Program – an advanced HW (hardware) exchange for complete peace of mind to support your business whatever your requirement is.

STORDIS also offers an environmentally friendly approach by installing BISDN’s Linux Distribution software to disaggregated Networking Bare Metal Switches already in place, reducing your capital outlay by re-using existing hardware and also reducing your waste.


BISDN was founded in 2012 in Berlin, Germany, and set out to develop the software needed in the rapidly changing world of software defined networking. Based on long-standing experience in the area of telecommunication as well as datacenter networking, BISDN focusses on high-performance whitebox switching and open network software solutions. With BISDN Linux as the core of most of their products, BISDN aims to build the free and open SDN solutions needed for the future world of networking. For more information, visit https://www.bisdn.de

Having followed the development of BISDN for many years, I am proud that we have become the first Value Added Distributor of the first fully open-source Switch Operating System. If you like Linux and you want your network switch to be provisioned, configured and monitored the same way as a Linux Server then you will love this operating system. When paired with the option for an enterprise-grade support service, all the requirements to use this platform in a modern datacentre environment will have been fulfilled.

Waldemar Scheck, STORDIS

We were not the first to have the idea of using the Linux networking for whitebox switches, as this dates back to the early days of SDN. I believe, however, that we are the first to fully open source the controller and the OS underneath. This is the next logical step towards open networking.

Dr. Hagen Woesner, BISDN

We are glad to see BISDN contribute its Linux-based platform to the open-source community. Open Network Operating Systems are gaining in popularity and provide customers with flexibility and choice and will further accelerate the open network movement.

We are happy to be able to introduce to you our #Back2Open Program for stranded Cumulus Linux users! Make the switch back to an actively supported and maintained Open Network Operating System (NOS) now – with a free NOS software license*.

Some background information: You have probably heard the news by now that Cumulus Linux and Broadcom are parting ways, after NVIDIA acquired Cumulus Linux.

This development has a major impact on anyone that is using a combination of Cumulus Linux with a network switch that is powered by a Broadcom ASIC and will require some form of action to avoid that negative impact.

Our #Back2Open Program was initiated for exactly that reason: We will help you switch from Cumulus Linux back to an actively maintained and supported Open Networking OS (NOS) – with a free NOS license*.
*Only the software support would need to be acquired.

While these three are closely linked to networking, they differ technically and practically. Many people find it challenging to distinguish between them because of the interrelation. A Software-Defined Network can be both open networking and open source. However, something can be open source but not open networking since they aren’t the same thing. With this in mind, figuring out what each of these does is essential to understand its benefit in the networking industry. 

Open flow or open source works in the same way as an API by configuring network switches. On the other hand, open networking provides for a breakdown of the complex nature of software and hardware to offer a more programmable and scalable network. This way, it can be configured to meet a variety of requirements. Open-source and open networking follow a common ground in that they are both open but differ in application.

SDN (Software-Defined Network) is a close-knit of programmable interfaces used in a network infrastructure to improve automation while providing network services. However, the term SDN has been used to define a variety of technologies. But, it can be specified explicitly in its application.

How to distinguish between Open Source, SDN and Open Networking?

It is excusable that many people fail to distinguish between the three because of their relation. However, they cannot be used interchangeably. This article provides insights to understand each of them and distinguish it from the other.

What is Open Source?

Simply put, open source is easily accessible, and the source code can be manipulated, reprogrammed, and scaled to meet requirements. This includes software and programs accessible to the public and can be shared almost by anybody. When the source code is available to anyone on the internet, the need to rework is increasingly possible. Anybody can view, modify, share, and even learn how to im[prove the software.

An Open Source is convenient for creating communication paths, technical communities and also helps construct networking equipment such as Ethernet switches. This networking model is highly favored by developers, vendors, engineers, and service providers. It draws great attention to anyone who appreciates developing a specific type of software and programs. While it sounds pretty simple, there is more than meets the eye! An open-source application or program requires one to comply with licenses. These may include General Public License (GNU) or Apache license. The license will define the terms, agreement, and conditions of the source code’s use and distribution. However, a second user may need to preserve or agree to the terms before redistributing or altering the code. This way, the name of the developer and/or authors is maintained and preserved.

What is Open Networking?

Open Networking is a unique combination of using bare-metal switch hardware (coming from such as ODM companies like Accton / Edgecore, Delta / Agema, UfiSpace) with a different NOS (Networks Operation Software) which could be a commercial one (ex. Pica8, IP Infusion, RTBrick, Pluribus Networks, Capgemini /Altran etc.) or open source (like SONiC or DENT) as long as you have compatibility with the CPU, U-boot and ASICs – other words saying so-called porting need to be done first. As those all mentioned NOS options are base on Linux, you are getting a chance to use a wide range of commercial or again open source tools for management, configuration, and automation such as Chef, Puppet, Ansible, or Grafana, Prometheus, and more.

Network engineers and administrators have found much success with this kind of system because they don’t have to rely on one specific software or hardware but instead choose from many options to create a solution that benefits their needs.

What is Software-Defined Network (SDN)?

SDN is essentially meant to decouple data packets within a network. It provides centralized management and configuration of the network instead of using several switches and servers throughout the network. This is crucial since an enterprise or network provider can respond efficiently to changing trends in the business environment.

SDN provides for programmable interfaces within a network, making it easier to apply them together with other networking technologies. There are 3 types of SDN architectural layers including;

  • Physical Network – This is the lowest layer in the network infrastructure. It includes devices such as ethernet switches forming the IT infrastructure of the network. Virtual switches can also be classified into a physical network.
  • SDN Application – This is the visible layer in an SDN design similar to modern-day applications and software. They run on dedicated programs and hardware, but the innovation comes from SDN applications.
  • SDN Controller – It is the linchpin to the entire infrastructure, linking both the virtual and physical network. It provides an avenue for integration and usability of the whole infrastructure.

In a modern application of a Software-Defined Network, a vendor will provide both the application and the SDN controller as a unit. However, the controller takes center stage as a crucial element for the entire network infrastructure.

Are they one and the same thing?

Well, there is a complete difference between Open Source, Software-Defined Network, and Open Networking. Both SDN and open source play a combined role in offering open networking. However, they are not equally the same. On the same note, both Open Networking and Open Source work under the same principle and concept of being open. But they are quite different.
From the definitions above, you will notice how they differ from the others in concept and application

Free Software vs Open Source Software

Many people tend to confuse Open Source software as free. The fact that it is accessible to the public for modification, sharing, and manipulation is not necessarily free. Some vendors opt to charge a one-time fee while others charge for installation, troubleshooting, and helping customers manipulate the software. In the former, a vendor may lose their licenses and will have to release the source code to the customer.
Before deciding on the perfect choice, choose the software that relates to you according to your actual needs.
