Resources, Services and APIs
Everything that Experimenters can interact with is referred to as a Resource
To run an experiment, you will configure the resources that you need.
This includes:
- Compute
- capable of having disk images loaded and saved
- users can log into them with ssh after provisioning
- Software Defined Radios
- FPGA images loaded with UHD
- Radio paramaters controlled with UHD or other API
- RF Frontends
- api to control switches, filters, and gain
- Network switches
- connectivity defined with API
- Optical Devices
- space switch, roadms, and other devices controlled with optical config service
Note, some resources will fall into more than one of the above categories, such as a compute machine with integrated SDR, like the USRP 2974
RF Control
A number of services is availabe for experimenters to manage various aspects of domains and resources. These include:
- RF Switch management service: service for management of RF switches in various sandbox nodes.
- Node RF control service: management of the RF front-end in large and medium outdoor nodes.
