Project Name

Unified Secure Channel


  • 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 with the controller, acts as a demuxer/muxer 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 a 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.

Bugzilla (summary of bug situation)

  • Bug List
  • 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.
