Has anyone experience with a tool to simulate delays in packet forwarding - Especially to simulate high delays as they occur in satellite networks? Have anyone already used a free tool based on linux, freebsd, (windows).
check out nist net [1]. it's running on linux as a kernel module. in it's original version it has some limitations. it can only generate constant delays or delays of a small random table in the kernel. if that's not enough and you need to model correct statistical properties of network traffic such as long-range dependence, then you should take my extendend version of nist net which works with pregenerated trace data. i did my master's thesis on "Trace-based network emulation".
if you need further information, please contact me offlist.
