tools starting from simple tools for listing end nodes and conversations to=
the more sophisticated tools such as Flow and IO graphs.</p><p>In the next=

look at the simple tools that provide us with basic network statistics; th=
at is, who talks to whom over the network, which are the "chatty" devices, =
what packet sizes run over the network, while in the next chapter we'll get=
into tools such as IO and Stream graphs, which provide us with much more i=
nformation about the behavior of the network.</p><p>There are some tools th=
at we will not talk about; those that are quite obvious (for example, <span=
class=3D"strong"><strong>Packet sizes</strong></span>), and those that are=
less common (such as <span class=3D"strong"><strong>ANSP</strong></span>, =
<span class=3D"strong"><strong>BACnet</strong></span>, and others).</p><p>T=
