The Shadow Simulator

Shadow is a unique discrete-event network simulator that runs real applications like Tor and Bitcoin, and distributed systems of thousands of nodes on a single machine. Shadow combines the accuracy of emulation with the efficiency and control of simulation, achieving the best of both approaches.

Also included are simple Internet topologies and a core plug-in for generating traffic between nodes and through SOCKS proxies.

Quick Setup (installs everything in ~/.shadow):

$ ./setup build --clean --debug
$ ./setup install
