Lonny Kruger posted about how to build a sample standalone network emulator source code for Visual Studio 2010 Beta 1 in those days. The good news is that driver portion of NEWT was transfered to Visual Studio 2010 Team to support the new load testing features, so then it became possible to develop NEWT-like tool. Unfortunately for lots of IT professionals out there, these SDKs are not generally available, so they have to engage with networking guys, their knowledge and their devices and networks to perform tests related to how well or bad their infrastructures work under different network conditions. This tool is now part of Games for Windows LIVE SDK and XBOX XDK. NEWT (Network Emulation for Windows Toolkit) is a fabulous network emulator tool that allows you to simulate different network conditions, and include ports, protocols and interface filters. NEWT also provides flexibility in filtering network packets based on IP addresses or protocols such as TCP, UDP, and ICMP. A variety of network attributes are incorporated into the NEWT emulation model, including round-trip time across the network ( latency), the amount of available bandwidth, queuing behavior, packet loss, reordering of packets, and error propagations. NEWT ( Network Emulator for Windows Toolkit) is a software-based emulator which can emulate the behavior of both wired and wireless networks using a reliable physical link, such as an Ethernet. All credits go for Lonny Kruger and Ivan Neganov.
