It receives input from sensors as well as from the reaction level and the reflec-
tion level. Reflection, a meta-process where the mind deliberates about itself,
at the top level receives no sensory input and has no motor output; it receives
input from below. The levels relate to speed. For instance, reaction should be
immediate, whereas reflection is consideration over time. Other variations of
this three-tier architecture have been derived in other research domains (see
In the future communications-paradigms research domain, a new con-
struct, a knowledge plane, has been identified as necessary to act as a per-
vasive system element within the network to build and maintain high-level
models of the network. These indicate what the network is supposed to do
to provide communication services and advice to other elements in the net-
work [

]. It will also work in coordination with the management plane and
data planes. This addition of a knowledge plane to the existing data and
management/control planes would form a three-tier architecture with data,
management/control, and knowledge planes [
