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: 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: A computer network system containing a concentrator with a backplane that has a plurality of lines. The backplane contains data lines and control lines for managing and organizing the transfer of data between modules in the concentrator. The system contains an intelligent bus arbiter system that allow the selection of transmitting modules to occur at the same time as actual data transfer is going on between other modules. The bus arbitration system is provided for determining a sequence of bus access. A memory is provided for building a table comprising entries. Each of the entries represents a module slot identification number. Each entry also has an entry link portion which links a given entry to another entry. The system also includes arbiter logic cycling through or sequencing through and reading the table from one entry to another entry based on the entry link portion.
