Abstract: A device may receive an indication of a multi-cluster switchover from a first cluster to a second cluster associated with the device, and may generate, based on the multi-cluster switchover, a heartbeat request that includes an information element to be utilized by a user plane device to associate with the device. The user plane device may be associated with the first cluster prior to the multi-cluster switchover. The device may provide the heartbeat request and the information element to the user plane device, and may receive, from the user plane device, a heartbeat response based on the heartbeat request and the information element. The device may establish a secure session with the user plane device based on the heartbeat response.

Abstract: A network device, with a user plane and a control plane, may establish a resiliency timeout and an association timeout for a packet forwarding control protocol utilized by the network device, and may detect expiration of the resiliency timeout. The network device may signal control plane or user plane applications based on the expiration of the resiliency timeout, and may cause the user plane to trigger a connected-pause state transition based on the expiration of the resiliency timeout.

Abstract: In some implementations, a network device may receive an indication of a switchover for a subscriber group that contains subsets of subscriber sessions. The network device may transition each subset of the subscriber sessions to a state associated with traffic forwarding. The network device may selectively transition each subset of the subscriber sessions from the state associated with the traffic forwarding to a state associated with traffic services.

Abstract: In some implementations, a network device may receive an indication that a user plane subscriber access device has rebooted. The network device may transmit based on the indication that the user plane subscriber access device has rebooted, an indication to refrain from notifying an access network that a logical port corresponding to a subscriber group created in a track-logical-port mode is associated with an active state.

Abstract: In some implementations, a redundant DBNG user plane device may maintain respective subscriber states of a plurality of primary DBNG user plane devices. The redundant DBNG user plane device may 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, of the plurality of primary DBNG user plane devices, is not active. The redundant DBNG user plane device may identify, based on determining that the particular primary DBNG user plane device is not active, a subscriber state of the particular primary DBNG user plane device. The redundant DBNG user plane device may operate, using the 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.

Abstract: A disaggregated broadband network gateway (DBNG) control plane system may be configured to receive a first initialization packet associated with a user device via a first user plane and a second initialization packet associated with the user device via a second user plane. The DBNG control plane system may be configured to determine, based on at least one of the first initialization packet or the second initialization packet, one or more load balancing parameters. The DBNG control plane system may be configured to cause, based on at least one of the one or more load balancing parameters, a communication session for the user device to be established via the first user plane and not via the second user plane.

Abstract: A network device may assign subscriber groups to logical ports of the network device, and may generate a load balanced group that includes the logical ports assigned to the subscriber groups. The network device may provide a backup logical port for the load balanced group, and may maintain the backup logical port in an oversubscribed state or a full state. The network device may identify a subscriber group failure for one of the subscriber groups, and may switch the one of the subscriber groups to the backup logical port based on the subscriber group failure.

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.

Abstract: In some implementations, a network device may identify a triggering event associated with a logical port. The logical port may be associated with a subscriber group that is associated with a user plane subscriber access device. The network device may assign, based at least in part on the triggering event, a logical port administrative state to the logical port.

Abstract: In some implementations, a disaggregated broadband network gateway (DBNG) control plane device may send, to a first DBNG user plane device that is an active DBNG user plane device for a subscriber group (SGRP), a first message indicating that the first DBNG user plane device is to be a backup DBNG user plane device for the SGRP. The DBNG may send, to a second DBNG user plane device that is the backup DBNG user plane device for the SGRP, a second message indicating that the second DBNG user plane device is to be the active DBNG user plane device for the SGRP.

Abstract: In some implementations, a network device may obtain a switchover indication associated with a switchover of a group of subscriber sessions from a first user plane subscriber access device to a second user plane subscriber access device.

Abstract: Time-varying conditions in a wireless network are simulated using an architecture that includes an enclosure for shielding a wireless device under test (“DUT”) from electro-magnetic interference, including other wireless devices; and at least one of: (1) a communications traffic generating device operable to generate communications traffic having selected characteristics; and (2) at least one dynamically adjustable attenuator in communication with the wireless device and the traffic generator. Embodiments of the architecture include wireless test equipment for testing operating range, roaming and capacity. The attenuator is used to adjustably attenuate signals between the device and the traffic generator over time during a test, whereby motion of the device is simulated. By connecting multiple access points, each associated with a dynamically adjustable attenuator, it is possible to force the DUT to roam between access points.

Abstract: Test equipment operable to evaluate handoff in wireless networks can be configured as an infrastructure test system or a client mobility test system. The infrastructure test system includes a plurality of client emulating devices and a client motion emulator for testing real access points. Each client emulating device is operable to emulate multiple individual virtual mobile devices (“virtual mobile devices”). The client motion emulator computes a mathematical representation of the modeled network and motion of virtual mobile devices in that network. The client motion emulator employs the mathematical representation to calculate path loss between virtual mobile devices and the real access points in the modeled network. The calculated path loss information is transmitted to the virtual mobile devices. Path loss of communications from a virtual mobile device to an access point is implemented via a programmable attenuator.
