Site convergence agent and associated method

A system for instantiating a network service comprising:

• at least one processor;
• a memory storing instructions that, when executed by the at least one processor, causes the system to perform operations comprising:
• receiving a request for the network service;
• in response to the request, generating a list of required resources in a required order for instantiating the network service, the required resources comprising one or more of infrastructure resources, network function resources, or workload resources;
• identifying a sequence of the required resources based on the required order;
• executing a site convergence agent (SCA) convergence loop operable to, for each of the required resources, implement the required resource by calling for the required resource to be created, updated, or deleted;
• determining a convergence of the required resources to the sequence of the required resources by comparing the implemented required resources with the list of the required resources;
• and
• deploying the requested network service by instantiating the implemented required resources.

A computerized system for instantiating a network service, comprising:

• one or more processors;
• and
• computer storage memory having computer-executable instructions stored thereon which, when executed by the one or more processors, cause the computerized system to:
• receive a request for a required network service;
• determine a required network service (NS) design for the required network service;
• store a required NS state configured to create a list of required resources in a required order for instantiating the required network service;
• sequence through the list of required resources in the required order and identify a sequence of required resources based on the order;
• converge towards the sequence of required resources, via a SCA convergence loop, by:
• a. implementing the required resource by calling for the required resource to be created, updated or delete a resource;
• b. determining a next required resource to implement;
• c. repeating steps a and b to convergence;
• compare the implemented resources with the list of required resource to determine convergence;
• and
• instantiate, via a controller, the or each implemented resource.
