Network fabric describes a mesh network topology with virtual or physical network elements, forming a single fabric.

What is it?

This trivial metaphor does not do justice to the industry term, which describes the performance and functionality of mostly L2 & L3 network topologies. For nodes to be interconnected and reach equal connectivity between each other, the term network fabric ( NF) completely omits L1 (trivial) networks.

Primary performance goals include:

  • Abundancy — sufficient bandwidth should be present, so each node achieves equal speed when communicating in the topology
  • Redundancy — a topology has enough devices, to guarantee availability and failure coverage
  • Latency

Multus CNI (Container Network Interface) is a novel approach to managing multiple CNIs in your container network (Kubernetes). Based on its name, which means multiple in Latin, Multus is an open-source plug-in, which serves as an additional layer in a container network, to enable multi-interface support. For example, Virtual Network Functions (VNFs) often depend on connectivity towards multiple network interfaces.

The CNI project itself, backed by the Cloud Native Computing Foundation, defines a minimum specification on what a common interface should look like. The CNI project consists of three primary components:

  • Specification: an API that lies between the network plugins…


Microservice-Ready Application for Managing Network Elements in Software-Defined Networks

What if I told you, that there is an out-of-the-box pre-packaged microservice-ready application you can easily use for managing network elements in your SDN use case? And that it is open-sourced and you can try it for free? Yep, you heard it right.

The application consists of lighty.io modules packed together within various technologies — ready to be used right away.

Do you have a more complex deployment, and are using Helm to deploy into Kubernetes? Or you just need to use Docker images? Or you want to handle everything by yourself and the only thing you need is a…


PANTHEON.tech has made StoneWork available on the GNS 3 marketplace. This makes it easy for anybody to try out our all-in-one solution, which combines multiple cloud-native network functions from our CDNF.io portfolio, in a separate environment.

This tutorial will give you the basics on how to set-up StoneWork in an environment, where you can safely test out interaction and its positioning within your (simulated) network.

The goal of this tutorial is to have a basic setup, where we will:

  • Setup StoneWork interface IP address
  • Set the status of StoneWork to UP
  • Verify the connection by pinging the address

StoneWork | An IPSec Appliance

Our CDNF.io portfolio is steadily growing. Our latest addition to the CDNF.io family is StoneWork.

Here, StoneWork enables you to securely and remotely access your management plane.

StoneWork is a solution which, thanks to its modular architecture, enables you to combine multiple CNFs from the CDNF.io portfolio, using only one data-plane, to increase the overall throughput, while keeping rich functionality.

One of the many features of StoneWork is IPSec, which we will talk about in this post.

Stonework is part of our CDFN.io portfolio. It is an enhanced , which serves as an all-in-one switch/

PANTHEON.tech is an avid open-source supporter. As the largest contributor to the OpenDaylight source-code, as well as being active in many more open-source projects and creating our own, we believe that open software is a way of enriching collaboration and making better products overall.

Open-source is also a philosophy of freedom, meaningfulness, and the idea that wisdom should be shared.

Practical consequences of software being open are far-reaching and have great significance — much bigger than an uninvolved observer would guess at a first glance. To see the consequences, you need to take a look at a big enough project…


OpenDaylight ‘s distribution package remained the same for several years. But what if there is a different way to do this, making distribution more aligned with the latest containerization trends? This is where an OpenDaylight Static Distribution comes to the rescue.

Original Distribution & Containerized Deployments

Let’s take a quick look at the usual way.

A standard distribution is made up of:

  • a pre-configured Apache Karaf
  • a full set of OpenDaylight’s bundles (modules)

It’s an excellent strategy for when the user wants to choose modules and build his application dynamically from construction blocks. …


PANTHEON.tech has enabled OpenDaylight to migrate to the current version of AKKA, 2.6.x. Today, we will review recent changes to AKKA, which is the heart of OpenDaylight’s Clustering functionality.

As the largest committer to the OpenDaylight source-code, PANTHEON.tech will regularly keep you updated and posted about our efforts in projects surrounding OpenDaylight.

Released in November 2019, added many improvements, including better documentation, and introduced a lot of new features. In case you are new to AKKA, here is a description from the official website:

[It is] a set of open-source libraries for designing scalable, resilient systems that span processor cores…


The Linux Foundation Networking: 2020 Year in Review shows PANTHEON.tech leading open-source enrichment and customer innovation adoption in SDN Automation, Cloud-Native, 5G & O-RAN.

Leadership and Contribution

PANTHEON.tech is pleased to showcase the Linux Foundation Networking “2020 Year in Review”, which highlights our continued commitment to open-source enrichment and customer adoption.

This report reflects a series of metrics for last year and we are extremely proud to be highlighting our continued leading levels of participation and contribution in LFN’s technical communities. As an example, PANTHEON.tech provided over 60% of the commits to OpenDaylight in 2020.

This is an extraordinary achievement, given this is…


ONAP (Open Network Automation Platform) is quite a trend in the contemporary SDN world. It is a broad project, consisting of a variety of sub-projects (or components), which together form a network function orchestration and automation platform. Several enterprises are active in ONAP and its growth is accelerating rapidly. PANTHEON.tech is a proud contributor as well.

What is ONAP?

The platform itself emerged from the AT&T ECOMP (Enhanced Control, Orchestration, Management & Policy) and Open-O (Open Orchestrator) initiatives. ONAP is an open-source software platform, that offers a robust, real-time, policy-driven orchestration and automation framework, for physical and virtual network functions. …
