RE: Stress Testing LAN/WAN

["Stephens, Josh" <Josh.Stephens () solarwinds com>]

To generate round-trip traffic you have to enable echo services on the
target host and then send to that port.

On a Windows box I think it's called "Simple TCP Services" and then you
send the traffic to TCP Echo.

HTH,

I have used Solarwinds Wan Killer, but have yet to discover a method of
initiating round-trip traffic from a single generator, but Solarwinds
can stress a GiGE MAN link using a desktop PC with a GiGE card as the
generator.

You can download a copy of the SolarWinds toolset from our website (the
eval is free).

There's a traffic generator in there called "WAN Killer". Give it a try.
