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.
