Abstract: In general, techniques are described herein for implementing priority channels by prioritizing and communicating control packets on an interface between a disaggregated Broadband Network Gateway control plane and the disaggregated Broadband Network Gateway user plane. In some examples, a method includes assigning, by a disaggregated broadband network gateway (DBNG) user plane device, a control packet for a control protocol to an assigned priority channel of a plurality of priority channels within a common tunnel for a shared interface with a DBNG control plane system, the DBNG user plane device physically separate from the DBNG control plane system; and sending the control packet to the DBNG control plane system using the assigned priority channel.

Abstract: In some implementations, a user plane (UP) device may receive a control packet indicating a logout associated with a subscriber session. The UP device may store an indication of the logout associated with the subscriber session. The UP device may determine, after storing the indication, that the logout associated with the subscriber session has not been completed within a subscriber logout period. The UP device may transmit an error indication indicating that the logout has not been completed within the subscriber logout period. In some implementations, a control plane (CP) device may receive the error indication indicating that the logout associated with the subscriber session has not been completed. The CP device may process the logout based at least in part on receiving the error indication. The CP device may transmit, based on processing the logout, a logout notification associated with the logout.

Abstract: A disaggregated broadband network gateway (DBNG) control plane system may receive an association setup request message from a DBNG user plane device, wherein the association setup request message is received via a state control interface between the DBNG control plane system and the DBNG user plane device. The DBNG control plane system may determine, based on the association setup request message, one or more capabilities of the DBNG user plane device and may thereby cause one or more additional state control interfaces to be established between the DBNG control plane system and the DBNG user plane device. The DBNG control plane system and the DBNG control plane system may communicate messages associated with a first message type via the state control interface and may communicate messages associated with a second message type via at least one of the one or more additional state control interfaces.
