Major Features

  • USC Agent provides proxy and agent functionality on top of all standard protocols supported by the device. It initiates call-home with the controller, maintains live connections with the controller, provides demux/mux for packets with the USC header, and authenticates the controller.
  • USC Plugin is responsible for communication between the controller and the USC agent . It responds to call-home with the controller, maintains live connections with the devices, acts as muxer/demuxer for packets with the USC header, and provides support for TLS/DTLS.
  • USC Manager handles configurations, high availability, security, monitoring, and clustering support for USC.
  • USC UI is responsible for displaying a graphical user interface representing the state of USC in the OpenDaylight DLUX UI.

Target Environment

For Agent

For Execution

  • Requires Java 7 compliant runtime environment.
  • Follow the OpenDaylight Lithium installation and user guide documentation to install OpenDaylight Lithium including USC features.

For Development

  • Requires Java 7 compliant runtime environment, Maven version 3.1.1.
  • Follow the OpenDaylight Lithium installation and user guide documentation to install OpenDaylight Lithium including USC features.
  • USC UI development requires DLUX set up in developer mode: DLUX Developer Mode

Known Issues and Limitations

  • 3402: Cast failure on exception branch in view channel rpc request. Workaround: A null shard service throws this exceptions, so wait until shard service is available before using the view channel API.
  • 3291: Remote channel request should use same controller for same session. Workaround: Use same controller for all sessions.
  • 3290: Remote session id conflicts with the local session id using same channel. Workaround: Suggest to restart usc if this edge case occurs due to session id conflicts.

Testing methodology

  • Code is covered by unit and integration tests
  • External System Tests are performed manually in Lithium (will automate in Beryllium).
