[clug] Network Simulator Software

[Aaron Smith]

Can anyone recommend some good network simulator software?

I need to change network latency and bandwidth for testing of network 
software. e.g. Simulate a fat pipe to the other side of the planet or a 
thin pipe to the other side of the building.

I was about to use The REAL Network Simulator on a linux based router 
(http://minnie.tuhs.org/REAL/) to customise network performance between 
two local networks but thought someone might be able to suggest a better 
tool.

The need features:
- ability to configure network latency
- ability to configure network bandwidth
- easy to configure and reconfigure (technical people other than me will 
me to use is in the future).


Thanks,

Aaron
