Hello all, I need to simulate a redundant topology using ns2 but I could not figure out how. The topology is like this:
NODE ----------------------- NODE A ----------------------- B It's basically two nodes with two links in between (one duplex and other simplex - then for ns2 is 3 links) -- and then I must be able to specify which link should be used for data to be transmitted from A to B. I thought that I could use routes -- but If I do so, I cannot tell which link should be used -- just the next hop (and there are two ways to reach B -- so how to specify a single link?). The code below shows where I'm having problem. #Create two nodes set nA [$ns node] set nB [$ns node] #Create two links between the nodes $ns duplex-link $nA $nB 1Mb 400ms DropTail blue $ns simplex-link $nA $nB 1Mb 40ms DropTail red #create manual routing (ref: pg 257 of ns-manual) $ns rtproto Manual #specify route #how to specify which link should be use? In this cause, which of the two links would be used by ns2? $nA add-route-to-adj-node -default $nB #In fact, I think that I have to specify only which link should be used.. and not even to deal with routing #end of script Thank you for your attention, Giovane
