= Resources, Services and APIs

Everything that Experimenters can interact with is referred to as a [wiki:Resources 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 [wiki:Hardware/sdr/usrp2974 USRP 2974]

== RF Control ==

A number of services is availabe for experimenters to manage various aspects of domains and resources. These include:

 * [wiki:Resources/Services/RFSwitch RF Switch] management service: service for management of RF switches in various sandbox nodes.
 * Node [wiki:Resources/Services/RFControl RF control] service: management of the RF front-end in large and medium outdoor nodes.

== SDR Control ==
* [wiki:Resources/Notes/KryptonUsage USRP 2974 Driver Installation and Access]
* [wiki:Resources/Notes/N310Usage USRP N310 Configuration and Access]
* [wiki:Resources/Notes/SerialConsole Node Serial Console]

== Compute Control ==
* [wiki:Resources/Images Disk Images]
* [wiki:Resources/Notes/LatencyTuning OS Latency Tuning]
