NETWORK ORCHESTRATION
First Claim
1. A method of network orchestration, the method comprising, by an orchestrator:
- obtaining a model of a physical resources part of a network, the physical resources part of the network comprising a plurality of physical resources, the model of the physical resources part of the network representing dependencies between different physical resources in the physical resources part of the network;
obtaining a model of a virtualised resources part of the network, the virtualised resources part of the network comprising at least one virtualised network function, the model of the virtualised resources part of the network representing dependencies between different virtualised resources in the virtualised resources part of the network;
performing at least one optimisation operation using the model of the physical resources part of the network and the model of the virtualised resources part of the network to identify an optimised mapping of the at least one virtualised network function onto at least one of the plurality of physical resources; and
instantiating the at least one virtualised network function on the at least one of the plurality of physical resources based on the identified optimised mapping.

Abstract
Measures, including methods, apparatuses and non-transitory computer-readable storage media, associated with network orchestration. A model of a physical resources part of a network and a model of a virtualised resources part of the network are obtained. The physical/virtualised resources part of the network includes a plurality of physical resources/at least one virtualised network function and represents dependencies between different physical/virtualised resources in the physical/virtualised resources part of the network. At least one optimisation operation is performed using the models of the physical and virtualised resources parts of the network to identify an optimised mapping of the at least one virtualised network function onto at least one of the plurality of physical resources. The at least one virtualised network function is instantiated on the at least one of the plurality of physical resources based on the identified optimised mapping.
