Should be of interest to any of you interested in net neutrality.
JS: in summary (as i understand things), deep packet
inspection has to do with network devices that are
installed on the primary backbone centers and that
are designed to inspect ,for all data traffic that
passes through them, not just the outer packet
information but each of the internal packets as well
as the payload information to determine the
application for which the payload is bound.
the issue regarding net neutrality is whether
such devices can (i.e should) be configured to
throttle individual packets based on their payloads.
if so, what would be the criteria? the primary
worry is prioritization based on fees: those entities
that pay for prioritization have the effect that
those that don't suffer slower pass-through.
a point i haven't seen mentioned (yet) is that of
security: if backbone data centers have the ability
to throttle packet flow, this could inhibit the
effects of denial of services, possibly spam, and
destructive attempts such as those that could cripple
the nation's electrical grid or emergency services.
this seems a worthy consideration, but throws the
entire decision area into the murky realm of policy.
