Embodiments of a device and method are disclosed. In an embodiment, a method of communications involves from a wireless sensor deployed at a customer site, connecting to a wireless access point (AP) deployed at the customer site and based on a private key stored in the wireless sensor, performing mutual authentication between the wireless sensor and an authentication server connected to the wireless AP.

Embodiments of a device and method are disclosed. In an embodiment, a method of network diagnostic of a network deployed at a customer site involves at a cloud server connected to the network deployed at the customer site, collecting connectivity state information of the network deployed at the customer site and at the cloud server, performing a network diagnostic operation based on the connectivity state information.

Embodiments of methods and a system to validate a change in a computer networking system are disclosed. In an embodiment, a method to validate a change in a computer networking system includes identifying, at a network management system, at least one candidate device, where a candidate device has a network connection to a device that is a target of the change in the computer networking system, collecting, at the network management system, metrics related to the at least one candidate device, triggering, by the network management system, the change at a target device, and validating, at the network management system, the change in the computer networking system using the metrics of the at least one candidate device.

A telemetry manager receives, from a network server, global data collection information about network components in an optical network device. The global data collection information includes identifiers for network nodes in the network components from which telemetry data are to be collected, and reporting frequency and encoding format for sending collected telemetry data to the network server. The telemetry manager identifies, from the global data collection information, local data collection information specified for a network component, and sends this information to a telemetry agent in the network component. The telemetry manager receives telemetry data generated by a network node of the network component, where the data is provided according to instructions in the local data collection information. The telemetry manager converts the telemetry data from its native format to an encoding format specified by the global data collection information, and sends the encoded telemetry data to the network server.

Nodes and methods are disclosed for protection and restoration to protect against multiple failures for multiple paths involved for the same service in mesh networks, including, determining, by circuitry of a first node in a mesh network, a failure of a working path between the first node and a second node, wherein the second node, when triggered by the failure of the working path, switches to a protection path. Methods further include establishing through transmission of at least one signal by circuitry of the first node at least one recovery path, for example, a restored-working path, after determining the failure of the at least one working path, wherein the at least one restored-working path carries a duplicate of the data traffic transmitted on the protection path in case of failure of the protection path.

Multi-level recovery in transport networks

A line card in a network node having a local memory coupled to a local controller and local logic circuit. The local memory in the line card stores state information for signals processed by the line card itself, as well as state information for signals processed by other line cards. The logic circuit and controller implement a same fault detection and signal processing algorithms as all other line cards in the group, to essentially effectuate a distributed and local hardware based control of automatic protection switching (APS) without interrupting a central processor. The line card also performs error checking and supervisory functions to ensure consistency of state among the line cards.

Each node in the network broadcasts its unique identifier to the other nodes. Each node assigns a different network address to each of the nodes based on the unique identifier received from the node. However, each node assigns the network addresses in a common predetermined manner. Thus, each node arrives at the same assignment of network addresses. In a preferred embodiment, the assignment of network addresses is maintained as an address table at each node.
