Distributed broadband network gateway stateful N+1 hot-redundancy

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a redundant disaggregated broadband network gateway (DBNG) user plane device, cause the redundant DBNG user plane device to:
• maintain respective subscriber states of a plurality of primary DBNG user plane devices,
• wherein the plurality of primary DBNG user plane devices communicate with a DBNG control plane device, that is associated with the redundant DBNG user plane device, to obtain update information associated with respective subscriber states of the plurality of primary DBNG user plane devices, and
• wherein the redundant DBNG user plane device communicates with the DBNG control plane device to obtain the update information from the DBNG control plane device;
• determine, based on maintaining the respective subscriber states of the plurality of primary DBNG user plane devices, that a particular primary DBNG user plane device is not active;
• and
• operate, using a subscriber state of the particular primary DBNG user plane device, as an active DBNG user plane device for traffic associated with the particular primary DBNG user plane device.
