**The open network tester for the IP networking community.**
The **BNG Blaster** is an open-source network tester for **access** and **routing** protocols.
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.
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.
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.
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.
