entry point into enterprise or service provider core networks. Examples include routers, switches,
integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN)
and wide area network (WAN) access devices.

Unlike the Fog and the Cloud, the primary goal of the ROOF computing layer is to provide real-
time computing needs for building the contexts and required actions along with efficient and
flexible connectivity to the Fog and Cloud providers. As the ROOF will be the first contact points
for heterogeneous physical things, it must be equipped with technologies that can handle
interoperability, mobility and importantly smart decision-making abilities to fulfil the goals of three-
layer architecture presented here.

The distributed AI based architecture will not only improve the fluidness of traffic flow and
promptness of decision-making but also will save ample amount of resources at the Cloud layer,
which can be used by future applications like cross-border interactions. This will open a new
paradigm for new business models, like inter-regional collaboration for law and order, international
travelling and global research activities. However, ensuring business uptake and regulatory
compliance in such an environment is critical and manual intervention is almost impossible
without an autonomous and more secure intermediate agent called, trust manager. The trust
manager essentially ensures trust across different domains. It allows free flow of data or services
while maintaining trust as it passes across different domains (each domain might have different
governance, regulations, administration, etc.). In this context, the main responsibilities of the
trust manager will be to regulate federated AI platform and ensure reliable and trustworthy data
aggregation and decision-making.
