Concepts

This is a brief overview of the main concepts and terms needed to follow Cosmos Overview/Workflow

Resources

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

Domains

Resources are grouped under Domains. Each domain won't interfere with any others, and they are reserved completely separately.

The hardware in a domain may span several sites.

Sites

Physical locations where hardware is installed.

A site consists of one or more nodes.

Nodes

  • Nodes refer to a set of radio, compute, and other resources meant to be used as a unit.
  • The resources in a node will share infrastructure such as power, networking, or RF frontends.
  • Therefore, the use of resources within a node must be coordinated to avoid interference.
  • It is possible to use a subset of the resources within a node

Reservations

Images

Images refer to a full disk image, that can be loaded onto, or saved from the testbed machines.

For instructions on how to work with images, refer to User Guide/Omf Quick Start

For details on the available images, Refer to User Guide/Image Versions
