netsniff-ng is is a free, performant Linux network analyzer and networking toolkit. The gain of performance is reached by zero-copy mechanisms, so that the kernel does not need to copy packets from kernelspace to userspace and vice versa. netsniff-ng consists of much more than only a network ... [More] analyzer. Next to the zero-copy sniffer itself, further tools like trafgen, a powerful zero-copy network packet generator, or ifpps, a tool that provides top-like kernel networking statistics, and curvetun, a lightweight curve25519-based multiuser IP tunnel, are being shipped.

In short: a demand model/simulator for highway tolls on regional road networks Vijka is a simulator for analyzing and estimating the number of vehicles that will use a highway, that is, its traffic volume. Given a road network and and a weighted list of origin/destination trip desires, Vijka ... [More] can perform the necessary demand assignments and output the traffic volume estimates and other interesting information. Vijka is also **fast**, and has been used to run, in only a couple of minutes, multiple scenarios (10+) of a large number of trips (each with its own cost perception) on detailed networks (~100k nodes, ~200k links).
