Hi All, I am not sure is it a right place to post here becuase I am newie to Java. But during to academic reason, i need to write a program which might already out of my knowledge. Just wonder some expert could provide some recommendation to me, Tks!!

The requirement is used Java to simulate a network with 3 nodes(2 machines and 1 router). What I need to do is to simulate a package flow from 1 node to the others. Do you have any idea what Java technique required(e.g. Link list, Node??) Sorry I really have no idea and still keep search around the internet, Tks so much!!!!!!
