A software defined network controller can be provided by a computing system that includes a processor. A service model that represents a service can be obtained. A network model that represents network resources that support the service can be obtained. Resources that support the service can be determined. Templates can be accessed to identify templates that relate to the resources. The templates identified can be assembled to obtain a template-based representation of the service. The template-based representation can be executed to determine if the service is ready for deployment. ## Claims ### Claim 1 A method comprising: compiling, at a computer system comprising a processor, a service model that represents a service; compiling, at the processor, a network model that represents network resources that support the service; determining, by the processor, resources that support the service; accessing, by the processor, templates to identify templates that relate to the resources; assembling, by the processor, the templates identified to obtain a template-based representation of the service; executing, by the processor, the template-based representation to determine if the service is ready for deployment; determining, by the processor, that the service is ready for deployment; determining, by the processor, that the resources are ready to support the service; issuing, by the processor, a first command to allocate the resources; and issuing, by the processor, a second command to load a function to the resources. ### Claim 2 (depends on 1) The method of claim 1, further comprising receiving an event at a service logic control, the event being received from an autonomous algorithm running at a network resource autonomous control, wherein the autonomous algorithm runs against data in a data collection analysis engine. ### Claim 3 (depends on 1) The method of claim 1, wherein the service model comprises a file in a modelling language. ### Claim 4 (depends on 1) The method of claim 1, further comprising: determining, by the processor, a process flow that supports the service;
