2nd equation

Pnet = 0.0006% + 0.000000015% + ( 0.0060% )^2 + 2 x ( 0.0080% ) = 0.000166%
The result (0.000166%) is wrong, should be: 0.01664%

Ring topology section, 2nd para

You say that a device wants to send a packet to
another on the same ring, the packet is sent downstream
"until it reaches the destination". Later, in the
same section, you say that the sender eventually
receives the packet it sent, with a marking showing
that the packet was received by the destination.
These are contradictory statements.

Also, you mix the usage of "frame" and "packet"
in this section

Figure 3-16

The paragraph spanning pp 90-91 refers to segment 1 on Figure 3-16 (p 89), but the
segments on Figure 3-16 aren't labelled. I figured it out from context, but at the
expense of time and clarity.

In the same paragraph, I don't understand how router Core B still has a valid
connection to the segment if the fiber has been cut.

second paragraph

The 27 bit mask should be 255.255.255.224
The 30 bit mask should be 255.255.255.252

I think you have a made a typo in printing 255.255.224.0 and 255.255.252.0 - but a
misleading typo.
