Embodiments of the present invention disclose an alarm information processing method, including: acquiring, by an EMS, a first alarm information set reported by a VNFM, where the first alarm information set is generated after the VNFM performs correlation analysis on at least one piece of NFVI alarm information and at least one piece of VIM alarm information; acquiring, by the EMS, a second alarm information set reported by a VNF, where the second alarm information set includes at least one piece of VNF alarm information; and performing, by the EMS, correlation analysis on the first alarm information set and the second alarm information set, and dispatching a configured work order for alarm information that has a correlation relationship. By using the present invention, a cross-layer association between alarm information can be implemented to reduce a quantity of work orders.

In accordance with an embodiment, described herein is a system and method for automatic migration of poller proxy services in a service bus environment. A singleton service framework component keeps a poller singleton application running on any of the managed servers in the cluster. The poller singleton application is registered with a cluster change listener, which listens for any state change in the cluster. Each poller proxy service is homogeneously deployed on each managed server in the cluster, and is associated with a poller engine configured to run on a particular managed server. When a managed server fails, the poller singleton application can migrate each poller engine configured to run on the failed managed server, to a running managed server, based on a preferred server list of the poller proxy service associated with that poller engine.

An arbitration method, apparatus, and system, relates to the field of computer technologies, where the arbitration method, executed by a first data center, includes viewing a preset arbitration policy when determining that communication between the first data center and a second data center is interrupted, and an arbitration device cannot perform arbitration, and continuing providing a service when determining, according to the arbitration policy, that the first data center is a preferred data center, or stopping providing the service when determining, according to the preset arbitration policy, that the first data center is not the preferred data center, where the first data center and the second data center are active-active data centers. Hence, the arbitration method, apparatus, and system solve a problem of a service interruption caused by a fault of the arbitration device, therefore an uninterrupted service is provided for a user.

Various exemplary embodiments relate to a method of offline traffic matrix aware segment routing. The method may include receiving a traffic matrix based upon all the traffic between nodes i and j that is routed in the network; and determining the amount of traffic between nodes i and j will be routed through node k, based on minimizing a maximum link utilization for the traffic matrix by determining that the total amount of flow on a link e in the network is less than the link's capacity.

A method for resolving split conditions in a port-extended network comprises receiving first information indicative of a first MAC address of a first controller on a first fabric link and second information indicative of a second MAC address of a second controller on a second fabric link. The method may also include determining that the first MAC address differs from the second MAC address and responsively determining that one of the first MAC address or the second MAC address was previously associated with a primary controller of the port-extended network. One of the first controller or the second controller is designated as the primary controller of the port-extended network based on the determination that one of the first MAC address or the second MAC address was previously associated with the primary controller.

A system (100) for dynamic orchestration is provided, the system configured to be used for embedding a virtual network into a physical infrastructure, the system comprising: a decision component (DC) which is configured to evaluate a performance of at least one orchestrator (O.sub.1, O.sub.2, . . . , O.sub.n) based on at least one parameter (P.sub.1, P.sub.2, . . . , P.sub.n), and which is configured to settle on a recomposing of the orchestrator (O.sub.1, O.sub.2, . . . , O.sub.n) based on the evaluated performance and, which is configured to provide a recomposing signal (RS.sub.1, RS.sub.2, . . . , RS.sub.n) when the recomposing is settled; and a recomposing component (RC) which is configured to execute the recomposing of the orchestrator (O.sub.1, O.sub.2, . . . , O.sub.n) when the recomposing signal (RS.sub.1, RS.sub.2, . . . , RS.sub.n) is received.

Provided is a method for managing a virtualized network function, comprising: an NFVO initializes a VNFM pool according to configuration information of the VNFM pool, wherein the configuration information includes an initial number of VNFMs managed by the VNFM pool, a maximum number of VNFMs managed by the VNFM pool, and a maximum number of VNFs managed by each VNFM in the VNFM pool; and the NFVO monitors a status of each VNFM in the VNFM pool, and, when an invalid VNFM is monitored, the NFVO ascribes one or more VNFs managed by the invalid VNFM to one or more valid VNFMs in the VNFM pool.

A system, computer-implemented method and computer program performs heartbeat messaging for managing connections for data communications. In one example method, an indication of a problem associated with a connection for data communication in a computing system or network is received. In response to receiving the indication, a heartbeat message is sent over the connection. The method monitors for a heartbeat response to the heartbeat message within a predefined heartbeat time interval. If a heartbeat response is received within the predefined heartbeat time interval, the method determines that the indication of a problem associated with the connection is invalid. If a heartbeat response is not received within the predefined heartbeat time interval, the method determines that the indication of a problem associated with the connection is valid.

An automatic service monitor in an information-technology environment performs regular search queries against generated machine data to derive performance measurements. The information technology environment is defined in terms of services provided by entities, and the performance measurements are defined as key performance indicators (KPIs) of the services. Generated machine data used by the search queries pertain to the entities performing the service. Definitional information for the services, entities, and KPIs is administered by a user to control the operation of the service monitor. Various aspects of such definitional information as well as related performance measurement information may be presented in a unified console display tailored to, and organized around, a particular service. The console display may serve as a central launch point by supporting user interaction to navigate to other specialized monitoring interfaces.
