Batfish is a network configuration analysis tool that can find bugs and guarantee the correctness of (planned or current) network configurations. It enables network engineers to rapidly and safely evolve the network, without fear of outages or security breaches.
Batfish was originally developed jointly by researchers at Microsoft Research, the University of California, Los Angeles, and the University of Southern California. Many others have since contributed to it.
Batfish is currently maintained by and also offered as a supported service by Intentionet.
