thrulay

Network capacity tester

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it. Special features of thrulay include: * For TCP, ability to measure round-trip delay along with throughput * For UDP, ability to measure - one-way delay, with quantiles - packet loss - packet duplication - reordering * For UDP, the ability to send precisely positioned true Poisson streams (microsecond errors in sending times) * Human- and machine-readable output (ready to be fed to gnuplot)
