<h1>BNG Blaster<a class="headerlink" href="#bng-blaster" title="Link to this heading"></a></h1>
|
||
<p><strong>The open network tester for the IP networking community.</strong></p>
|
||
<p>The <strong>BNG Blaster</strong> is an open-source network tester for <strong>access</strong> and <strong>routing</strong> protocols.</p>
|
||
<p>Originally developed as an access protocol tester, the BNG Blaster has undergone a
|
||
significant evolution, transforming into a comprehensive network testing tool that
|
||
now encompasses both access and routing functionalities. Its scope has expanded beyond
|
||
the assessment of access protocols and now encompasses a broader spectrum, involving
|
||
the evaluation of network functionalities at large. Contrary to its nomenclature,
|
||
the BNG Blaster isn’t restricted only to BNG (Broadband Network Gateway) testing.</p>
|
||
<p>It simulates a massive number of PPPoE and IPoE (DHCP) subscribers, encompassing
|
||
IPTV and L2TP (LNS). Additionally, it supports all common routing protocols such
|
||
as IS-IS, OSPF, LDP and BGP. This allows for comprehensive testing of both BNG
|
||
and non-BNG routers, enabling end-to-end evaluations.</p>
|
||
<p>The included traffic generator serves various functions. It can be used to verify
|
||
forwarding, conduct QoS tests, and measure convergence times. With the capacity to
|
||
handle millions of separate tracked flows, it allows for thorough verification of
|
||
every forwarding state within a complete internet routing table. Furthermore, it
|
||
enables the transmission of traffic to each specific QoS queue present in
|
||
service edge routers 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 introduction from <a class="reference external" href="https://youtu.be/4rmwf6livyI">DENOG15</a>
|
||
can be found on YouTube. There are even more videos and articles
|
||
listed below.</p>

|
||
<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>
|
||

|
||
<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>
