A method for delivering operations, administration and maintenance (OAM) configuration information includes obtaining, by a control node in a communication network and from at least two of a plurality of first nodes in the communication network, advertisement packets, wherein each of the advertisement packets comprises indication information indicating a corresponding path detection mode supported by a sender of each of the advertisement packets; determining, by the control node based on a path detection mode to be used and the advertisement packets, a detection path; and delivering OAM configuration information to a head node in the detection path and a tail node in the detection path.

Disclosed by the present application are a system and method for multi-device media data management, and a robot device. A detection module detects a device located within a detection range, and determines according to a detection result whether to add the device to a device management list. A storage module obtains media data generated by each device in the device management list and stores the media data in a backup system in association with a corresponding tag. An instruction module receives an instruction of a user and analyzes the content of the instruction, the content comprising a tag and management type corresponding to the media data. A management module performs a management operation on corresponding media data according to the analyzed content. Thus, a plurality of devices may be actively detected and discovered, media data in corresponding devices may be obtained according to an instruction of the user, and be safely and reliably stored; in addition, intelligent searching for a plurality of tags may be conducted. Therefore, media data of a plurality of devices of a user may be integrally managed safely.

A computer implemented method of adapting a software defined network (SDN), the SDN operating with a set of network appliances in communication via network connections and the SDN comprising a control component operable in communication with at least a subset of the network appliances to control communication via the SDN, the method including receiving a representation of the logical arrangement of the SDN including a definition of appliances configured to provide communication for the SDN and network connections therebetween; receiving a measure of a performance metric for the SDN; receiving a forecast demand for the SDN; using a heuristic search to search a library of possible adaptations to the logical arrangement to identify a sequence of adaptations of the SDN that, when implemented, satisfy the forecast demand for the SDN and provide an improved measure of the performance metric of the SDN; applying the identified sequence of adaptations to the SDN by modifying the logical arrangement for use by the control component in subsequent communication via the SDN.

An access profile includes configuration characteristics that are defined using device and operating system agnostic attributes. Thus, the access profiles are not necessarily dependent or otherwise tied to any particular vendor or network OS. When a system administrator configures one or more service access points, the system administrator need only specify the vendor and network OS agnostic characteristics that are to be associated with the service access point. A configuration generator can generate vendor specific and/or network specific configuration commands and data from the vendor and network OS agnostic access profile attributes. The generated configuration commands and data can be provided to a network device hosting the service access point using a vendor specific and/or network OS specific configuration application program interface.

A method for managing a network device that includes a network operating system (NOS) and a third-party network operating system (3PNOS) includes detecting a 3PNOS state change in a 3PNOS database managed by the 3PNOS, translating the 3PNOS state change into a network device state change, storing the network device state change in a state database managed by the NOS, in response to the storing: detecting a change in the state database by a NOS agent executing in the NOS, initiating, in response to detecting the change in the state database, an update to hardware on the network device by the NOS, wherein the 3PNOS does not directly manage the hardware.

A protective wiring device disposed in an electrical distribution system, the device comprising: a plurality of line terminals comprising a line-side phase terminal and a line-side neutral terminal; a plurality of load terminals comprising a load-side phase terminal and a load-side neutral terminal; a line conductor electrically coupling the line-side phase terminal to the load-side phase terminal; a neutral conductor electrically coupling the line-side neutral terminal to the load-side neutral terminal; a controller configured to transmit wirelessly data derived from signals present on at least one of the line conductor or the neutral conductor and to receive wirelessly receive at least one command.

Implementations are described herein for commissioning a distributed control node (DCN) to a process automation network. In various implementations, one or more messages transmitted on the process automation network by the DCN announcing that the DCN has joined the process automation network may be detected. Based on the one or more messages, one or more operational technology (OT) capabilities of the DCN may be determined. Based on the one or more OT capabilities, the DCN may be commissioned to the process automation network, e.g., by configuring the DCN to cooperate with one or more other process automation nodes on the process automation network to implement an at least partially automated process.

This disclosure describes techniques for providing a network diagnostic system with on-premise node processing and cloud node processing to optimize bandwidth usage and decrease memory footprint. The on-premise node may receive streaming telemetry from connected network devices and encode to the telemetry data into filtered data objects. The on-premise node may determine whether the state of a network device has changed to determine to push the filtered data object to a cloud node for further diagnostic analysis. The cloud node may include a gateway and a pool of proxy servers, wherein each proxy server is designated to perform diagnostic analysis on a single product type.
