Confirmed errors:



{38}  Second Formula;
Trying to follow the calculations on the page, i came to the conclusion that the
resulting formula is slightly incorrect.

The formula in the book is (latex)
$_k p _n = \frac{n! \cdot (2m-1)^{n-k}}{k! \cdot (n-k)! \cdot (2m)}$
but should be
$_k p _n = \frac{n! \cdot (2m-1)^{n-k}}{k! \cdot (n-k)! \cdot (2m)^n}$



{134}  Second paragraph;
This page discusses the use of the type/length field, and points out that the 802.3
standard uses it as a length field, so it's still necessary to identify the type.
Using SNAP this is possible.  The last sentence of the second paragraph says "The
presence of a type rather than a length value in the 'length/type' field
automatically tells the receiving station to look for LLC information later in the
packet."  This is backwards.
It should say "The presence of a length rather than a type value..."
because that's the reason SNAP is used; to overcome the fact there is no type
mentioned.
