About Facebook NetNORAD UdpPinger
NetNORAD is a system to treat the network like a “black box” and troubleshoot network problems independently of device polling.
UdpPinger is an open-source part of NetNORAD. It is our high performance UDP packet generation, reflection and collection library. It is used internally as the basis for very wide ECMP loss and latency profiling. This release provides two simple binaries, uping and upong, which provide a trivial wrapper to the libraries.
