BNG Blaster
|
|
===========
|
|
|
|
The **BNG Blaster** 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.
|
|
|
|
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.
|
|
|
|
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.

from `DENOG13 <https://youtu.be/LVg6rlVEfNU>`_ can be found on YouTube. There is
|
|
also an article in the

`APNIC blog <https://blog.apnic.net/2022/05/26/bng-blaster-the-open-network-tester-for-the-ip-networking-community/>`_
|
|
where we explained our motivation for this project.

|
The BNG Blaster has been completely built from scratch in **C**. 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 (*O(1)*) library. The
|
|
`timer library <https://github.com/rtbrick/bngblaster/blob/main/code/common/src/timer.h>`_
|
|
was built to start, restart and delete the protocol session FSM timers quickly and at scale.

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.
|
|
|
|
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.
|
|
|
|
Our mission is to build better networks with open test suites.
