Abstract: There are provided measures for resource placement control in network virtualization scenarios. Such measures exemplarily comprise, in a network virtualization scenario, determining, by a first network entity managing a virtualized network function, constraints related to said virtualized network function, transmitting, by said first network entity, information indicative of said constraints to a second network entity managing resource capacity in said network virtualization scenario, and deciding, by said second network entity, resources or resource capacity to be allocated for said virtualized network function, based on said information indicative of said constraints.

Abstract: Systems, methods, apparatuses, and computer program products for virtualized network function (VNF) decomposition are provided. An embodiment of the invention includes to first decompose the Network Function into smaller blocks: application, platform, and resources (i.e., compute, network, and storage), then manage the decomposed application and platform parts by separate entities (e.g., EM/VNFM). This decomposition may be applied to the Network Elements (i.e., the current building blocks of telecommunication networks) and to the VNFs.

Abstract: Systems, methods, apparatuses, and computer program products for moving VNF instances between network service instances are provided. One method includes, when a real network service is being instantiated, transmitting or receiving a move virtualized network function (VNF) operation to move at least one virtualized network function (VNF) instance from a source network service to a target network service.

Abstract: The Fault Management (FM) in the Network Function Virtualization (NFV) environment may benefit from various methods. For example methods for fault escalation or de-escalation may be beneficial. A method can include requesting a change in a severity of a virtualized resource alarm. The method can also include deciding to change a severity of a virtualized resource alarm. The requesting the change in the severity can be based on the identified reason.

Abstract: Systems, methods, apparatuses, and computer program products for a service model management request. The method may include receiving an end-to-end network service model for network services. The method may also includes determining a set of domain services that are required to be able to provide an end-to-end network service defined by the end-to-end network service model. The method may further include checking whether at least one management domain is capable of providing the required set of domain services. The method may also include requesting, when the at least one management domain is not capable of providing the required set of domain services, to prepare the at least one management domain to become able to provide the required set of domain services. In addition, the method may include receiving a notification from the at least one management domain indicating an availability to provide the required set of domain services.
