Cross-cutting, representing the loci of functional computations and states, and
concern interactions representing the flow of information and state communication.
Guided by the first view CellNet abstracts the core network concerns into applicationoriented,
communication-oriented and resource-oriented functions and allows for
concern federation thus addressing the cross cutting functional aspects among the
previously identified core concerns. Figure 2 (left) models the CellNet component and
for better understanding we present it superimposed on the TCP/IP model in figure 2
(right). Yet we emphasize, as indicated in the figures, that the CellNet framework
does not impose layering among its defined abstractions allowing for diverse interfunctional
communication
The NCs accompanied by the network configuration template framework present a new paradigm for
building networks. However, to be realized within the present legacy network we
propose attaching specialized NCs to existing protocols according to network
functional decomposition as dictated by the CellNet framework. For example, the
reliable transport service provided by TCP can be encapsulated into an AOC while
socket management will be controlled by a COC.
