(Don't quote me...... hehe) but I always believed that Token Ring was a logical ring, but a physical star. Check out (careful for wrap)

The other talks about how IBM's Token Ring requires a physical star (stations connected to MSAUs) while IEEE 802.5 doesn't specify a physical topology. Having said that, everything is subjective. Although stations may connect to a common MSAU, (from what I understand) the MSAU connects the endstations into a physical ring, so I could see the physical topology being labeled as a ring. Also, I could see how the logical ring could be referred to as a bus, never a star tho. So, I would say: physical star, logical ring. But if I had to choose between the 2 you mentioned, I'd pick: physical ring, logical bus. Mike W. Dave Luancing wrote: > > I have conflicting reports.
