I have been reading the large number of messages that make
statements about HOW MANY REPEATERS CAN YOU HAVE in an Ethernet
(802.3) network.  Most comments seem to range around the picture
in chapter 8 of 802.3 or some vendors literature.

It seems to me the first question to ask is, what determines the
number of repeaters a network can have.  The second question is
WHY?  Anyone that is not on the 802 committee know?

Hint, it is obscure enough that you probably wont get the answer
from the 802.3 book, but I suggest you look in the supplement
with the full chapter 9.

802.3 is allegedly working on a document, that will not be part
of the standard, that will explain all the various topology
considerations as they understand them today.  This will also
contain the reason for limits and possibly the harm done if a
limit is exceeded. This sub-committee has been working for about
2 years.  You may want to let the 802 committee know that it is
important.

Post your answers and comments to the conf. so all can see the
importance of the topology information.  Are you watching Pat?

PS: One major problem the sub-committee has is the definition of a NETWORK.
