Fibre networks are built.
Let's make them run.
Fibre is on the doorstep, but many households stay on cable and DSL because the upgrade seems high-effort for low reward. Fibre isn't cheaper than the legacy copper network, so it must improve other areas: speed, latency, energy & operational efficiency.
BISDN supplies ready-made OLTs and a software BNG that runs on commodity servers. Developed in Berlin with support in English or German, with the option of operational support.
The OLT is a standard switch with PON modules
Our software assembles commodity hardware switches and pluggable PON (GPON/XGS-PON) modules into an OLT that behaves like a chassis with line cards and ports, managed according to Broadband Forum TR-383 and TR-385.
You only buy ports once connections are activated, not in advance.
Software BNG on the server of your choice
BNGbox separates control from the data path: the control plane manages sessions and communicates with your RADIUS server, while the user plane forwards traffic using DPDK and hierarchical QoS.
As the load grows, an additional user plane is added on another server. For the servers running daily in our lab, we give you throughput and latency.
You don't have to do this alone
Your OLTs, your optics, your RADIUS, your OSS: before anything goes into your network, we test it against the stack in the BISDN Lab.
We then support you with the rollout, preparations for the EU Cyber Resilience Act and, if you wish, operations. Our team in Berlin does this directly, in German or English.
How to measure sovereignty
The European Commission sets it out in the Cloud Sovereignty Framework: code you can read and build yourself, a supply chain you know, and a provider you can replace. We measure all three products against these criteria.
BISDN Linux is a free operating system for whitebox switches with Broadcom ASICs, built on the open source SDK.
BNGbox and PONbox are proprietary software built on open components and open interfaces that allow you to change vendors. The OLT switches use ASICs from Microchip, with an open SDK, or from Marvell, whose SDK is accessible under contract.
