Does someone implement fcoe (fibre channel over Ethernet)with NS3(network simulator)?
 

I have to implement fcoe using ns3(it is a network simulator),and I wonder if there is anyone who has achieved before or is doing now.Please,I have no idea at all.

Read the "Question Guidelines" link in my posting signature. We are happy to help you with specific problems and questions, but please don't ask us to look things up or write your scripts for you. There is ample documentation on NS3 and writing scripts, from their own website...did you start there?

There are also references to the FCOE algorithms, and some sample TCL scripts you can find with a brief Google search.
