[ns] Mac protocol for duplex links

Mon Feb 8 14:43:12 PST 2010

Hello every body

If I want to use mac/802.3 in a circular topology between every two nodes,
I think I have to use duplex-link for wired Ethernet
but I'm not sure duplex-link function uses which mac type?
and how to add Mac/802.3 to this type of topology?

thanks
