All Implemented Interfaces:

java.lang.Runnable

public class ThreadedTrace

extends java.lang.Thread

ThreadedTrace.java runs 50 traceroutes at a time (in 50 different threads) putting the results into files named "tracesN" where N=1,50. Each thread does 500 traceroutes from random servers to random destinations. USAGE: java ThreadedTrace destsFile tracesPerThread numThreads

• destsFile (default IPDestination.txt) is IP addresses to trace to.
• tracesPerThread (default 500).
• numThreads (default 50).
