Fog Topologies

Fog topologies can exist in many forms, and the architect needs to consider several aspects when designing an end-to-end fog system. In particular, constraints such as cost, processing load, manufacturer interface, and east-west trafficking all come into play when designing the topology. A fog network can be as simple as a fog-enabled edge router connecting sensors to a cloud service. It can also grow in complexity to a multi-tier fog hierarchy with different degrees of processing ability and roles at each tier simultaneously distributing processing loads when and where necessary (east-west and north-south).  Determining factors of the models are based on:

• Data volume reduction: For example, is the system collecting unstructured ...
