How many people learn about networks from certification courses or
in school, anyway? It was always my impression that people learnt
mainly by listening to other people.
I think there is often a directed graph of information flow for
particular subjects. There will be nodes in the graph which correspond
to people who have done research, and who speak with some accuracy.
There are other nodes which listen selectively to the interpretations
of others, derive rules of thumb and pass their filtered wisdom onto
other nodes, but do no research from sources that might be considered
Actually, I would assume it to be the other way around: if you only
If networking on the front lines is an informal oral tradition more

terminology to continue to be "taught" long after it stopped having

The effectiveness of this information-sharing network is hampered by
the unreliability of individual nodes to filter information they
receive, the inconsistent manner in which the information is processed,
the near-complete absense of filters on information passed to other
nodes, and the ad-hoc summarisation that happens throughout the network
regardless of the intentions of the origin nodes. Sounds almost eerily
Many ISPs provide a fertile learning environment for people who are
able and willing to learn, regardless (in spite of!) of initial
training and qualification.
However, I seem to think that there are lots of people in organisations
that run IP networks who don't have the opportunity to learn how to do
lots of different things, and many of them don't have the time, ability
or inclination to go research questions from the bottom up. Rules of
thumb and networking myths abound in that environment. The people who
are most able to appreciate finer technical points are also those who
are most likely to get bored and go find a more interesting job
somewhere else, etc, etc.
