Re: Token Ring defined [7:24643]
The term Token-Ring describes the original IBM specification and the subsequent IEEE 802.5. However 802.5 does not specify a physical topology. Original IBM's TokenRing specifies a star topology with all workstations connected to a Multistation access unit (MAU)ie Physical star logical ring. h1 | | h2-(Mau)-h4 | | h3 Token flows from h1 to h2 to h3 to h4 then back to h1.

RE: Token Ring defined [7:24643]
(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) http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/tokenrng.htm http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/introlan.htm The above links, one classifies Token Ring as a logical ring, which makes sense. 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.

Re: Token Ring defined [7:24643]
Both are wrong. Physically, it is a star all connected to a token ring MAU. Logically, it a ring with token passing.

I have conflicting reports. I see in one of my books that token ring is a physical ring - logical star. The next book claims a physical ring - logical bus. Which is correct? -D.L. __ Do You Yahoo!?
