Disclosed herein is a network management apparatus, comprising: a correlating information storage unit configured to store correlating information that correlates an error that may occur when executing a workflow to a way of resolving the error, the workflow defining a series of network construction processes consisting of a plurality of processes; a log collection unit configured to collect logs related to executing the workflow; a workflow stop unit configured to stop executing the workflow when an error occurs during the workflow being executed; an error handling unit configured to, during the workflow being stopped, refer to the correlating information based on the logs and determine a handling dealing with the error to perform the handling; and a workflow resuming unit configured to resume, when the error is resolved by the handling, the workflow from a process corresponding to the handling among the plurality of processes.

Network management apparatus, network management method and network management system

A network management apparatus includes at least one memory configured to store program code; and electric circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code, the electronic circuitry configured to: store configuration information on devices or functions that constitute a virtualized environment of a network; acquire, as property information of the workaround, information associated with one or more devices or one or more functions to which a workaround for a specific hardware or software problem is to be applied; extract the one or more devices or the one or more functions serving as an application target of the workaround by referring to the configuration information based on the property information; and request to execute the workaround with respect to the application target.

Disclosed herein is a network management apparatus, comprising: a correlating information storage unit configured to store correlating information, about a failure that occurs, that correlates a notification notified when the failure occurs to a workaround for the failure; a notification acquisition unit configured to acquire, a plurality of notifications notified in relation to a plurality of components related to a device in which the failure has occurred, respectively; a failure determination unit configured to determine whether the failure is a known failure in which the notification is correlated to the workaround or an unknown failure, by referring to the correlating information based on the plurality of notifications; and a workaround determination unit configured to determine, when the failure is determined to be the known failure, the workaround that is correlated to a notification determined according to a predetermined ordering of the components, as the workaround to be applied.

A network management device executes acquisition processing, determination processing, and implementation processing. The acquisition processing is for acquiring notification information that is issued in response to a failure occurring in a physical server or a virtual machine constructed in the physical server in a network virtual environment. The determination processing is for determining, in a case where the notification information is acquired, whether or not healing processing for recreating the virtual machine in which the failure has occurred needs to be implemented, based on information related to the failure. The implementation processing is for automatically implementing the healing processing in a case where it is determined that the healing processing needs to be implemented.

Network management for automatic recovery in the event of a failure

The present disclosure aims to provide a core node capable of appropriately allocating a radio resource of a RAN Slice allocated for a specific service to a radio terminal that uses this specific service. A core node according to the present disclosure includes: a determination unit configured to determine a radio resource to be allocated in accordance with a service provided for a radio terminal; and a communication unit configured to transmit resource identification information indicating the radio resource determined in the determination unit to a base station that manages a plurality of radio resources for each RAN Slice associated with a service.

A VIM is a VIM for managing each virtualized resource that is included in an NFV environment including virtualized resources including a physical machine in which a virtual machine having a VNF being a virtualized communication function is implemented, and the VIM includes a switching unit for switching a network flow from a virtual machine of a migration source to a virtual machine of a migration destination, or switching a system between an Active (ACT) system virtual machine of a migration source and a Standby (SBY) system virtual machine of a migration destination.

Virtualized resource management node and virtual migration method for seamless virtual machine integration

At least one general-purpose server is connected to a PE module via Ethernet (trademark). A control unit of the PE module controls a PE circuit and multiple fail memory in a real-time manner, temporarily stores fail information stored in the multiple fail memory, performs data processing on the fail information, and transfers the fail information thus processed to the general-purpose server. Each general-purpose server is controlled according to a computer program so as to perform redundancy analysis for a DUT based on the data received from the PE module.
