Other products do this too (Score 1)

There are a number of products that do network impairments in the market. Our company, PacketStorm Communications (www.packetstorm.com), sells a network emulator that not only delays, drops and reorders packets but provides traffic conditions and packet modifiers. These allow network designers to do "what if" experiment to determine if their network can support the quality of service they are promising.The major users of our product are telecommunincations equipment manufacturers and service providers. And our product doesn't require Windows. These things aren't cheap -- packet-over-SONET, DS3 and ATM interfaces aren't exactly priced like jelly beans. But for the specialized testing required for voice over IP, streaming video and similar applications they are what you need. People interested in trying out network impairments should check the NISTnet web site at the National Institute of Standards and Technology. NISTnet is a linux kernel module that can do basic network impairments. It's available for download from their web site.
