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.
