- Aether 2.1 models have been developed by performing some restructuring on the 2.0 models. Each onos-config target now represents a separate target. The sdcore-adapter, API, GUI, and other components have been updated to use these new models.
- As part of a Project Pronto demo performed in May, a new edge-to-edge communication mechanism was developed. We demonstrated a camera application on an edge at Stanford being controlled by a controller on an edge at Princeton. In addition to control, screenshots from the cameras were transmitted between edges.
- Stanford and Princeton University research regarding drone flight was updated to use the latest Aether software stack, and demoed as part of the May Pronto demo.
- Aether-in-a-Box on Hardware Radios has undergone continued development and documentation and is available as a lightweight platform for people to quickly bring up a physical on-premise deployment. Aether-in-a-Box for Developrs also continues to be usable with simulated radios for those who do not have physical small cell hardware.
- Development continued on enodebd, a service responsible for configuring and monitoring small cells.
- Work continues on implementing a new API layer for Aether, as well as implementing a new analytics engine.
