Networks
- A network model is any real-world network applications model.
Common network models include electric power grid, communications
networks, highways, petroleum distribution pipelines, and water
distribution pipes and channels, and the virtual networks of actual
traffic and resource flows over those physical networks. These are
commonly called the critical infrastructure (CI) networks.
- A graph may represent a single layer of a system's infrastructure,
such as power distribution, communications, transportation,
financial distribution, or physical structure elements. The graph
links represent the available distribution channels or dependencies
of the modeled network.
- Multiple graphs are commonly used to represent the multiple
layers of critical infrastructures as a single multi-network model,
each graph representing a completely different network (such as
electric power versus transportation), with
completely different network elements, property fields, and
associated dynamics agent models.
- Given a set of graphs, each with its own set of nodes and
links, their properties, and element behavior models, links may be
used to represent relationships between the elements of the separate
networks. These can indicate power used to keep communications
nodes up, fuel transportation to keep power generators running,
and communications message traffic running over a communications
physical network infrastructure. Ignoring the internal links in
each network's graph representations allows the collection of
graphs to be seen as a semantic graph representation of the
networks and their interconnects.
