WANem (Wide Area Network Emulation) is an awesome tool for emulating a WAN in your test/dev environment or even a demo lab. I use it in my demo lab to show customers how the technologies might behave in their environment.
WANem is a piece of software running on Knoppix, a well-known Linux distribution based on Debian. It comes in two forms:
- As an ISO that is launched through a LiveCD at computer startup.
- As a VMware Virtual Appliance that can be launched from a VMware platform.
