Method and apparatus for dynamically adapting a software defined network

A software defined network manager, comprising:

• a processing system including a processor;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
• receiving a first service request via a network;
• transmitting a query to service layer equipment according to the first service request that is received;
• receiving, from the service layer equipment, a first plurality of service requirements to fulfill the first service request responsive to the query;
• transmitting, responsive to receiving the first plurality of service requirements, a request for network resource capacity information to a plurality of instantiated software defined network controllers, previously instantiated into the network;
• and
• receiving network capacity information from the plurality of instantiated software defined network controllers;
• determining an insufficiency of software defined network controllers according to the first plurality of service requirements and the network capacity information of the plurality of instantiated software defined network controllers, to obtain a determined insufficiency;
• and
• instantiating into the network, another software defined network controller, responsive to the determined insufficiency, to fulfill the first service request, wherein the first plurality of service requirements are met, in part, by the plurality of instantiated software defined network controllers that are instantiated and, in part, by the another software defined network controller.

A method, comprising:

• receiving, by a processing system including a processor, a first service request via a network;
• providing, by the processing system, a query to service layer equipment according to the first service request that is received;
• obtaining, by the processing system and from the service layer equipment, a first plurality of service requirements to fulfill the first service request responsive to the query;
• providing, by the processing system and responsive to receiving the first plurality of service requirements, a request for network resource capacity information to a plurality of instantiated software defined network controllers, previously instantiated into the network;
• and
• obtaining, by the processing system, network capacity information from the plurality of instantiated software defined network controllers;
• determining, by the processing system, an insufficiency of software defined network controllers according to the first plurality of service requirements and the network capacity information of the plurality of instantiated software defined network controllers, to obtain a determined insufficiency;
• and
• instantiating, by the processing system, into the network, another software defined network controller, responsive to the determined insufficiency, to fulfill the first service request, wherein the first plurality of service requirements are met, in part, by the plurality of instantiated software defined network controllers that are instantiated and, in part, by the another software defined network controller.
