$\Textit{Bifr ost}$ is a programming model for implementing networking based on physical space. It addresses the challenges of existing cloud-based architectures by using bigraphs to represent spatial containment relationships and connectivity. This allows for policy scopes based on physical boundaries, location-based device naming, instantiation of spatial services, and spatial organization while maintaining local autonomy. $\textit{Bifr ost}$ enables direct communication between adjacent devices, the need for explicit gateways due to physical barriers, and spatially aware applications that bridge local control with global coordination.
