An interworking service entity receives server registration requests including indications of service layer protocols used by each server, maintains a repository of server information, and uses the repository for interworking requests of devices to servers of different protocols based on a server type provided in discovery requests. Other matching information may include, for example, server security protocol, supported services, service territory, availability, capacity, or loading, as device information or preferences, such a supported service, supported interface type, or a supported device type.

Techniques for implementing rollback of infrastructure changes in an infrastructure orchestration service are described. In certain examples, an infrastructure orchestration service is disclosed that manages both provisioning and deploying of infrastructure assets within a cloud environment. The service receives a plan comprising a set of instructions associated with a set of infrastructure assets of an execution target and identifies a first state of the set of infrastructure assets. The service executes the set of instructions in the plan to achieve a second state for the set of infrastructure assets. Based in part on the executing, the service receives a trigger for rolling back the plan to restore the set of infrastructure assets in the plan to the first state and executes a rollback plan for the plan. The service then transmits a result associated with the execution of the rollback plan.

A method is disclosed that includes receiving a request to display a service-monitoring user interface that illustrates performance of one or more services that are each provided by one or more entities. Each service is associated with a stored service definition that identifies the one or more entities, and each entity is associated with stored entity definition information that identifies machine data produced by or about the entity from one or more sources. The method further includes causing display of the service-monitoring user interface illustrating performance of each service via an aggregate key performance indicator (KPI) that characterizes a respective service as a whole, and a plurality of aspect KPIs that each characterize an aspect of an associated service. Each KPI is defined by a search query that produces a value derived from the machine data identified by the entity definition information, the value indicative of a measure of the service at a point in time or during a period of time. The machine data is produced by one or more components within an information technology environment and reflects activity within the information technology environment.

The present application describes a method and apparatus for updating a service in a service layer function of a network. In particular, a method for adding a service is disclosed. Initially, a request is received at a service enabler function located in the service layer function to add the service. A service description of the requested service is reviewed to understand its capabilities. A verification request is sent to a service capability located in the service layer function. Further, another service layer function or application is notified that the requested service is enabled.

Embodiments of this application provide a service management method and apparatus, so as to cover service level indication information at interfaces between various management network elements in NFV MANO, and further perform differentiated resource allocation and fault recovery for services based on the service level indication information. The service management method includes: receiving, by a first management unit, a first message sent by a second management unit, where the first message includes first identification information, the first identification information is used to obtain first information, the first information includes information used to obtain first service level information, and the first information is a network service NS deployment flavor DF or a virtualized network function VNF deployment flavor DF; and determining, by the first management unit, the first service level information based on the first identification information and the first information.

Example methods and systems are provided a network device to perform tunnel-based service insertion in a public cloud environment. An example method may comprise establishing a tunnel between the network device and a service path. The method may also comprise: in response to receiving a first encapsulated packet, identifying the service path specified by a service insertion rule; generating and sending a second encapsulated packet over the tunnel to cause the service path to process an inner packet according to one or more services. The method may further comprise: in response to receiving, from the service path via the tunnel, a third encapsulated packet that includes the inner packet processed by the service path, sending the inner packet processed by the service path, or a fourth encapsulated packet, towards a destination address of the inner packet.

Methods, systems, and computer-readable storage media for receiving a record including a set of attributes, each attribute having an attribute value, the record representing automatic execution of an IT process within a managed system, retrieving a model representing historical executions of the IT process and including a set of distribution parameters associated with a first type of attribute and a set of probability distributions associated with a second type of attribute, determining, for a first attribute, a first score based on distribution parameters and a value, determining, for a second attribute, a second score based on a probability distribution and a value, the second attribute being of the second type of attribute, and selectively indicating that the IT process is anomalous based on an outlier score.

The disclosure is directed to providing virtual network functions to a customer node by a communication system with a provider node in an automatic, traceable, and auditable way. The provider node includes a retrieving module, a validation module, and a deployment module. The retrieving module is configured to retrieve a notification signal, wherein the notification signal is indicative of a selected one of a plurality of virtual network functions and the customer node. The validation module is configured to establish service level agreement data and to validate the agreement service level data, based on the notification signal. The deployment module is configured to selectively transmit a deployment signal to a communication node depending on the validation of the service level agreement data for providing the selected virtual network function to the customer node.
