Cloud-managed fiber access networks

Cloud-managed fiber access networks

Ranging from ONU to BNG, we provide network access components which can be deployed individually or in any combination.

Based on long-standing experience in the areas of telecommunication and data center networking, BISDN focuses on high-performance whitebox switching and open network software solutions.


Our Offer

Cloud-hosted PON controller – we do IT for you

We integrate hardware underneath a common access controller. This includes our whitebox OS as well as a vBNG, a PON controller and LI functionality.

BISDN develops software for cloud-based network access. Our end customers are small and medium sized carriers, whom we serve directly or in cooperation with system integrators.

For system integrators, we license and brand our software as well as offer adaptation of existing control interfaces to our controller.

The integration of disaggregated network components requires technical knowledge that carriers may not have. We therefore host our solutions in public or private clouds to make deployment easier. Thus, our customers do not need to deploy their own infrastructure to manage their networks.

In addition to our software products, we offer both, industry-leading consultancy services for a smooth integration into existing networks and professional software maintenance. Hence, network operators will be in a position to increase their network capacity while reducing cost and improving efficiency.

Open Source and Memberships

Open Source is at the core of everything we do! 

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 our whitebox operating system BISDN Linux, our Intel-DPDK-based soft switch, and our Revised OpenFlow Library (rofl), which facilitates the development of controllers and datapath elements. Roflcommon is a C++ library offering a generic OpenFlow endpoint, while Rofl-datapath is an ANSI-C implementation of an OpenFlow pipeline. 
It is easily portable to multiple compute and switching platforms, including ARM, MIPS and FPGA.
