A network management apparatus according to an embodiment includes: a storage device configured to store information indicating a correspondence relationship between information objects related to a logical layer, information objects related to a physical layer in a network configuration, and information objects related to a facility layer which are objects in which the information objects related to the physical layer are housed; an acquisition unit configured to acquire an information object related to an occurrence path of a failure in the logical layer of the network configuration, from the storage device; and a search unit configured to search for, among the information objects related to the facility layer stored in the storage device, an information object related to the facility layer and the physical layer associated with the information object related to the occurrence path of the failure acquired from the acquisition unit, as a candidate for a facility that causes the failure.

In some aspects, the disclosure is directed to methods and systems for monitoring and isolating issues over physical layer (layer 1) paths using Flexible Ethernet (FlexE) protocols via client-based operations, administration, and maintenance (OAM) management. Each node within a FlexE communications path may dynamically insert, extract, and/or replace OAM messages from FlexE data streams as needed to ensure that the OAM messages may be provided unimpeded to a destination (e.g. monitoring server or other device), as well as inserting additional monitoring data (e.g. bit error rates, delay measurements, loss measurements, threshold crossing alerts, or other such monitoring notifications or data) for intermediary nodes.

A method for generating a topology view of an industrial parallel redundancy protocol (PRP) network includes: detecting, by one or more processors, a plurality of nodes on the PRP network; determining, by the one or more processors, a first set of the plurality of nodes that connects to a first local area network (LAN); determining, by the one or more processors, a second set of the plurality of nodes that connects to a second LAN; determining, by the one or more processors, connections between the plurality of nodes; and generating, by the one or more processors, the topology view of the PRP network comprising a topology view of the first LAN and the second LAN according to the determined connections.

Described are systems and methods for jointly optimizing Wide Area Network (WAN) and Local Area Network (LAN) network communications. In one embodiment, a management device communicatively interfaced with a WAN and a LAN includes a collection module to collect LAN information from the LAN and WAN information from the WAN; an analysis module to jointly analyze the collected WAN information and the collected LAN information to identify an operational condition; and an implementation nodule to initiate a management event responsive to the operational condition being identified. In one embodiment, the management event includes generating and transmitting a diagnostics report responsive to a fault being identified. The management device may further generate and execute instructions to remedy the diagnosed fault.

Using various functionalities of electronic devices such as applications that gather location information to provide a service to the user can come at the cost of significant power consumption, and consequently battery drainage. A data sharing system enables the creation of a network of participant devices where participant devices in the network can take turns in collecting and sharing data with the rest of the participant devices in the network. The one or more participant devices can share the obtained data through Bluetooth® low energy (BTLE) or other low consumption channel, so that the ensemble of participant devices could have better battery life, higher availability, and/or better accuracy, compared to each device having to individually obtain the data.

Systems, methods, and computer-readable storage devices for reducing the amount of management ports (and associated cabling) for a top-of-rack server environment. Whereas other server management configurations have cabling connecting each node in multiple multi-node chassis in a server rack to a top-of-rack, systems configured as described herein designate a single node as a point of communication for the multi-node chassis. The designated node forwards communications for all nodes in the chassis to a chassis management controller, which acts as a distribution point for all communications within the multi-node chassis, with the benefit of only a single connection being required between the multi-node chassis and the top of rack switch.

A system and method for mapping a network to facilitating configuration is disclosed. Address registration information is appended to an enhanced local management interface message sent between devices in a network of routers and switches. A network management system for an outside network can use that information to map out the network and configure the network as needed. The address registration information includes an Internet Protocol address and an interface index. The interface index includes both slot and port number.

Cloud based Wake-on-LAN (WoL) for thin clients can be performed to allow a cloud based management server to wake up a thin client prior to an update command (or other communication) being transmitted to the thin client to ensure that the thin client will receive the update command. Cloud based WoL can therefore facilitate the deployment of updates to thin clients by providing a way for the administrator to wake up the thin clients from the cloud.

Decoupling of a first machine from a plurality of machines in a network is disclosed. Each machine has a machine identifier. The plurality of machines are organized into a linearly ordered sequence in accordance with a predefined order of the machine identifiers. The first machine is configured to receive a query from a preceding machine and propagate the query to a succeeding machine in the linearly ordered sequence. Prior to decoupling from the network, the first machine informs respective presence of a first subset of machines to a second subset of machines that are not overlapping with the first subset of machines. The first subset of machines includes a machine having a lower machine identifier relative to the machine identifier of the first machine, and the second subset of machines includes a machine having a higher machine identifier relative to the machine identifier of the first machine.

In accordance with one example embodiment, there is provided a system configured for virtual local area network (VLAN) blocking on a virtual port channel (vPC) member link to handle discrepant virtual network instance (VNI) to VLAN mappings. In other embodiments, the system can be configured for providing Virtual Switch Interface Discovery Protocol (VDP) and virtual switch enhancements to accommodate discrepant VNI to VLAN mappings. In another example embodiment, an apparatus is provided that includes a processor, and a memory coupled to the processor, where the apparatus is configured such that if a server is connected through a virtual port channel, a VDP is used to notify the server of different VNI to VLAN mappings. In another embodiment, the apparatus can extend a VDP Filter Info Field to carry a set of VLANs mapped to a VNI, keyed by leaf MAC addresses that serve as bridge identifiers.
