Hello,
During my search about Graduation Project Ideas I found an idea about Virtual Router
I know that there exist a virtual router in windows7 and it works well but when searching about virtual router
in Linux i found the following:

"In Linux there is a Kernel level router but on configuring in kernel level will cause some curious problems so we can do software router in user level"


I've no experience in Linux so, i want to understand the nature of these problems???
and what is the different between kernel level and user level ???
and is it a beneficial idea to develop a virtual router working in Linux in a user level??
