Packetstorm WAN simulation units have the capability to capture and save actual network impairment characteristics. The PacketStorm 'network capture' WAN simulation feature launches test packets to a remote site and measure the characteristics of that link. These real world impairments are then stored as an impairment set that can be reused in a lab environment. These captured impairments are implemented by impairing traffic on a packet by packet basis so that any real network impairments that may vary due to time or event, are captured and replayed through WAN simulation. In addition, the PacketStorm can capture and replay live data to provide generation and impairments while not connected to the production network through WAN simulation.
