Abstract: A computer network device (such as an access point, a switch or a router) that has multiple user interfaces is described. During operation, the computer network device may execute program instructions for the user interfaces and a shared messaging module, where a given user interface includes an agent corresponding to an application. When a message associated with the application is received via a user interface in the user interfaces, the corresponding agent in the user interface may extract a command or operation from the message. Then, the shared messaging module may translate the command or operation into a common format of the application. Moreover, the shared messaging module may provide (or route) the translated command or operation addressed to the application via a single communication path associated with the application and the agents for the application in the user interfaces.

Abstract: Segmenting personal area networks (PAN) in a computer network using regions, which may include: associating a first client device to a first PAN, where the first PAN is assigned to a first region from a plurality of regions; receiving an indication that the first client device is in communication with a first computer networking device; identifying whether the first computer networking device is a member of a plurality of computer networking devices that service the first region; selecting one of a first identifier or a second identifier based on whether the first computer networking device is or is not a member of the plurality of computer networking devices; and communicating the selected one of the first identifier and the second identifier to the first computer networking device. The first computer networking device may be configured to tag PAN network traffic from the first client device using the provided identifier.

Abstract: Computer networking devices and controllers thereof may communicate via a secure tunnel. Aspects of the present disclosure provide methods, systems, and devices that facilitate establishment of such tunnels. For example, a method may include: generating, by a computer networking device, a tunneling capabilities message indicating a plurality of different tunnel types supported by the computer networking device; transmitting the tunneling capabilities message to a controller; receiving, from the controller, a tunneling selection response message indicating one of the plurality of different tunnel types; requesting, by the computer networking device, establishment of a tunnel of the one tunnel type indicated by the tunneling selection response message; and establishing the tunnel of the one tunnel type between the computer networking device and the controller.

Abstract: Devices, methods, and systems that provide transmitting of messages between different units of a multi-unit system in response to instantiated multi-unit transactions. For example, a method may include: identifying, by a first unit of a multi-unit system of computing devices, an event has occurred that triggers initiation of a transaction; generating, by the first unit, a transaction identifier associated with the transaction, the transaction identifier comprising a unit identifier of the first unit and an application identifier of an application associated with the event; and transmitting, from the first unit and to a second unit of the multi-unit system, the transaction identifier as part of an inter-unit message.

Abstract: During operation, an electronic device may store, in memory, information associated with operation of the electronic device, such as during communication and processing of one or more packets or frames. Furthermore, an error-event monitor in the electronic device may, during a time interval, analyze at least a portion of the stored information to detect an occurrence of an error event in one or more types of error events in the electronic device. When the error event occurs during the time interval, the electronic device may perform a remedial action and may persist, in the memory, at least a second portion of the stored information associated with the error event. Otherwise, when the error event does not occur during the time interval, the electronic device may overwrite, in the memory, the stored information with additional information associated with operation of the electronic device during subsequent communicating and processing.

Abstract: An electronic device is described. The electronic device includes a stack of computer network devices, such as a stack of switches and/or routers. This stack of computer network devices includes data planes and ports for directing packets or frames in a wireless network based at least in part on destinations of the packets or frames. Moreover, the electronic device may include multiple controllers (such as processors) that operate as master nodes and that perform network functions for the stack of computer network devices using a database. This database may include a common database that is accessible by the multiple controllers or multiple instances of the database in the multiple controllers, where the multiple instances of the database are synchronized.
