6200networks.com: WAN Emulation Toolkit

Filed under: Cisco,Cisco Certification,Home Lab — cciepursuit @ 7:14 pm

How cool is this? (hat tip: Cisco IOS hints and tricks blog):

NIST Net is a network emulation package that runs on Linux. The NIST Net network emulator is a general-purpose tool for emulating performance dynamics in IP networks. The tool is designed to allow controlled, reproducible experiments with network performance-sensitive/adaptive applications and control protocols in a simple laboratory setting. By operating at the IP level, NIST Net can emulate the critical end-to-end performance characteristics imposed by various wide area network situations (e.g., congestion loss) or by various underlying subnet technologies (e.g., asymmetric bandwidth situations of xDSL and cable modems).

Once NIST Net has completed starting up, you see a menu from which you can launch the emulation tool with different network settings: Please select a preset from the following options:
————————————————–
1: 40ms round-trip delay, T1 bandwidth, 0.5% packet loss
2: 60ms round-trip delay, T1 bandwidth, 0.5% packet loss
3: 80ms round-trip delay, T1 bandwidth, 0.5% packet loss
4: 100ms round-trip delay, T1 bandwidth, 0.5% packet loss
5: 120ms round-trip delay, T1 bandwidth, 0.5% packet loss
6: 160ms round-trip delay, T1 bandwidth, 0.5% packet loss 
7: Custom Settings
8: Stop WAN Emulation
9: Exit 

BTW…if your wanting the NistNET .iso you can download it and other industry tools from CCO (login required) @ the following location:http://www.cisco.com/cgi-bin/tablebuild.pl/fe_util
