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.
Claims15
A method in a network virtualization environment, the method comprising:
- instantiating a source virtualized network service (NS) instance and a target virtualized network service (NS) instance, wherein the source and target virtualized network service instances comprise respective combinations of virtualized network function instances configured to perform a service;
- transmitting or receiving a move virtualized network function (VNF) operation to move a virtualized network function (VNF) instance from the source virtualized network service (NS) instance to the target virtualized network service (NS) instance, wherein the operation includes a virtualized network service (NS) instance identifier of the target virtualized network service (NS) instance to which the virtualized network function (VNF) instance is to be moved and a virtualized network function (VNF) identifier to identify the virtualized network function (VNF) instance to be moved.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to
- instantiate a source virtualized network service (NS) instance and a target virtualized network service (NS) instance, wherein the source and target virtualized network service instances comprise respective combinations of virtualized network function instances configured to perform a service;
- transmit or receive a move virtualized network function (VNF) operation to move a virtualized network function (VNF) instance from the source virtualized network service (NS) instance to the target virtualized network service (NS) instance, wherein the operation includes a virtualized network service (NS) instance identifier of the target virtualized network service (NS) instance to which the virtualized network function (VNF) instance is to be moved and a virtualized network function (VNF) identifier to identify the virtualized network function (VNF) instance to be moved.
