É basicamente um "load average" de uma determinada direção do fluxo
entre pares.


The main part of the display lists, for each pair of hosts, the rate at
which  data  has been sent and received over the preceding 2, 10 and 40
second intervals. The direction of data flow is indicated by arrows, <=
and =>. For instance,

foo.example.com  =>  bar.example.com      1Kb  500b   100b
                 <=                       2Mb    2Mb    2Mb

shows,  on  the  first  line, traffic from foo.example.com to bar.exam-
ple.com; in the preceding 2 seconds, this averaged 1Kbit/s, around half
that  amount over the preceding 10s, and a fifth of that over the whole
of the last 40s. During each of those intervals, the data sent  in  the
other  direction was about 2Mbit/s. On the actual display, part of each
line is inverted to give a visual indication  of  the  10s  average  of
traffic.  You might expect to see something like this where host foo is
making repeated HTTP requests to bar, which is sending data back  which
saturates a 2Mbit/s link.

By  default,  the  pairs  of hosts responsible for the most traffic (10
second average) are displayed at the top of the list.
