| Current 10Mbps Ethernet insist that packets have a minimum size of 64
bytes. If typical transmission media operate at propagation speeds of
200 x 106ms-1
a. Compute the theoretical maximum end-to-end length of the
network, if CSMA/CD is to
operate reliably, but all other factors are to be ignored.
b. Why must the end-to-end length be somewhat shorter than
this for reliable operation?
c. If the speed of Ethernet is increased to 1Gbps, what would the
theoretical maximum length be?
d. Can you suggest any techniques that would allow longer lengths to be
used, without losing CSMA/CD?
