In a source-based subnetwork, where does the flow direction go?

In a source-based subnetwork, the flow direction is designed to move away from the subnetwork controller. This is because the subnetwork controller serves as the source of flow within that specific subnetwork, managing and directing the distribution of resources, data, or utilities. Once a flow is initiated at the source, it is intended to propagate outward through the components of the subnetwork, ensuring that resources reach the necessary endpoints or users.

This design allows for efficient management of the network resources, as the controller dictates the flow's starting point and intended pathway. By directing the flow away from the controller, it creates a system where resources can be effectively allocated and utilized throughout the subnetwork, ensuring optimal performance and resource distribution while minimizing redundancy and confusion.
