<h1>BNG Blaster<a class="headerlink" href="#bng-blaster" title="Permalink to this headline"></a></h1>
|
|
<p>The <strong>BNG Blaster</strong> is an open-source network tester
|
|
for access and routing protocols. It can emulate a huge amount of
|
|
PPPoE and IPoE (DHCP) subscribers including IPTV, and L2TP (LNS).
|
|
There are various routing protocols supported like ISIS and BGP.
|
|
So you can use it for end-to-end BNG and non-BNG router testing.</p>
|
|
<p>You can use the included traffic generator for forwarding verification,
|
|
QoS testing or to measure convergence times. The traffic generator supports
|
|
millions of separate tracked flows. This allows you to verify every single
|
|
forwarding state of a full-feed internet routing table. You can also send
|
|
traffic to every single QoS queue of your service edge router with detailed
|
|
per-flow statistics like receive rate, loss or latency.</p>
|
|
<p>The BNG Blaster is used by leading network operators like Deutsche Telekom AG
|
|
with their famous Access 4.0 project, network hard- and software vendors like
|
|
RtBrick and many more.</p>

<p>A short <a class="reference external" href="https://youtu.be/EHJ70p0_Sw0">introduction</a> and a good presentation
|
|
from <a class="reference external" href="https://youtu.be/LVg6rlVEfNU">DENOG13</a> can be found on YouTube. There is
|
|
also an article in the
|
|
<a class="reference external" href="https://blog.apnic.net/2022/05/26/bng-blaster-the-open-network-tester-for-the-ip-networking-community/">APNIC blog</a>
|
|
where we explained our motivation for this project.</p>
|
|
<img alt="BNG Blaster Interactive" src="_images/bbl_interactive.png" />
|
|
<p>The BNG Blaster has been completely built from scratch in <strong>C</strong>. This includes user-space implementations
|
|
of the entire protocol stack. The core is based on a very simple event loop that serves timers and
|
|
signals. The timers have been built using a lightweight constant time (<em>O(1)</em>) library. The
|
|
<a class="reference external" href="https://github.com/rtbrick/bngblaster/blob/main/code/common/src/timer.h">timer library</a>
|
|
was built to start, restart and delete the protocol session FSM timers quickly and at scale.</p>
|
|
<img alt="BNG Blaster Architecture" src="_images/bbl_arch.png" />
|
|
<p>This project will be actively maintained and further evolved by RtBrick. We are fully committed to building
|
|
a project for the community and take issue and enhancement requests seriously. We are looking forward to any
|
|
kind of contributions, new features, bug fixes, or tools. Even contributions to the documentation are more
|
|
than welcome.</p>
|
|
<p>If you are interested in the BNG Blaster, or simply looking to find out more about it, we recommend going through
|
|
the examples in the quick start guide.</p>
|
|
<p>Our mission is to build better networks with open test suites.</p>
