BISDN Linux 3.5.0 released
October 26th, 2020
This release adds the link aggregation feature. It is now possible to configure bonded interfaces on a switch while using the bonding modes ‘balance-rr’,’active-backup’ and ‘802.3ad’. This release only supports layer 2 forwarding and bridging for bonded interfaces, meaning it is not possible to add and/or use IP addresses or any routing features on top of these new bonded interfaces. These layer 3 features will be added in the following releases. Download the latest builds from our repo

The open source operating system for whitebox switches. Turns your switch into an SDN switch with an Open Flow interface, or – alternatively- you can have the SDN controller directly on the switch.BISDN Linux data sheet.pdf
All our solutions are built on and around our core product BISDN Linux.
Get in touch with our distributors for supply. They will deliver to your doorstep.
For a large Tier1 carrier BISDN developed and piloted a Wi-Fi network which extended home routers by a centrally operated wifi network.
We have built a virtual Broadband Remote Access Server (vBRAS) prototype, based on the CUPS approach (Control User Plane Separation).vBNG Whitepaper.pdf
In our capacity as Certified Integration Partner (CIP) for Tibit Communications, we have set up a lab in Berlin. Here we are showcasing the interoperability of the pluggable OLTs (Optical Line Terminals) with various switch platforms and with ONUs (Optical Network Units).
If you would like to learn more about pluggable OLTs on whiteboxes, please contact us. We provide remote access to the lab, and we are here to help.
BISDN projects and tools
We open source networks
Open platforms require open interfaces. OpenFlow was at the beginning of the era of whiteboxes, breaking the vendor-lock-in of network devices. A vast amount of new solutions have since emerged from the open source community and from commercial operators.
We combine the ease-of-use of Linux networking with SDN and state-of-the-art packet processing platforms. For this purpose we have open sourced three core elements:
We provide baseboxd, a deamon that offloads Linux kernel forwarding and routing to hardware switches. baseboxd is open source. It closes the gap between well-established Linux open source routing projects, such as FRR, and whitebox switches.
It’s essentially SDN without the difficult part. No need to program any interfaces, just configure the entire router like a Linux box. Hardware acceleration centuplicates the router performance. Only buy the hardware and download the rest. If you like we will support you – just get in touch to learn about our support schemes.
More details on the Router are available on the dedicated project website.
We address the challenges of enhanced packet processing on non-ASIC environments and generic compute platforms with our eXtensible DataPath Daemon (xdpd) – a datapath framework that supports various packet processing platforms.
Check out the Intel-DPDK-based soft switch on github.
For those working on solutions in OpenFlow, our Revised OpenFlow Library (rofl) facilitates the development of controllers and datapath elements. Roflcommon is a C++ library offering a generic OpenFlow endpoint. Rofl-datapath is an ASNI-C implementation of an OpenFlow pipeline.
It is easily portable to multiple compute and switching platforms, including ARM, MIPS and FPGA. Check out the code on github.
We are members of the following programs and projects
We are actively participating in research activities in SDN and NFV. We have been particularly active in the following research projects:
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.
