Method and system of template-based dynamic network slicing

A system for template-based dynamic network slicing, the system comprising:

• a processor;
• and
• a memory communicatively coupled to the processor, wherein the memory comprises processor instructions, which when executed by the processor, cause the processor to:
• create service requirement set associated with a service request based on the plurality of characteristics in the service request, wherein the service requirement set comprises service characteristics, service performance requirements, and service dimensions associated with the service request, and wherein a plurality of resource attributes and a plurality of requirement attributes are associated with the service requirement set;
• identify a network slice template hierarchy based on the service requirement set, wherein the network slice template hierarchy comprises information associated with at least one of suitable templates for end-to-end network slice, network slice subnets, and corresponding constituents;
• select one of reusing one of at least one of existing network slice instance and creating a new network slice instance, based on the identified network slice template hierarchy and the service requirement set;
• instantiate a service associated with the service request using one of the at least one of existing network slice instances and the new network slice instance;
• monitor the service and one of the at least one of existing network slice instances and the new network slice instance, in response to instantiating the service, wherein a result of the monitoring is used for detecting and fixing at least one issues identified during monitoring of instantiated service;
• and
• perform adaptation of at least one threshold and at least one factor used to perform network slicing, based on the at least one issues identified.

A non-transitory computer-readable storage medium having stored thereon, a set of computer-executable instructions causing a computer comprising one or more processors to perform steps comprising:

• creating service requirement set associated with a service request based on a plurality of characteristics in the service request, wherein the service requirement set comprises service characteristics, service performance requirements, and service dimensions associated with the service request, and wherein a plurality of resource attributes and a plurality of requirement attributes are associated with the service requirement set;
• identifying a network slice template hierarchy based on the service requirement set, wherein the network slice template hierarchy comprises information associated with at least one of suitable templates for end-to-end network slice, network slice subnets, and corresponding constituents;
• selecting one of reusing one of at least one of existing network slice instance and creating a new network slice instance, based on the identified network slice template hierarchy and the service requirement set;
• instantiating a service associated with the service request using one of the at least one of existing network slice instances and the new network slice instance;
• monitoring the service and one of the at least one of existing network slice instances and the new network slice instance, in response to instantiating the service, wherein a result of the monitoring is used for detecting and fixing at least one issues identified during monitoring of instantiated service;
• and
• performing adaptation of at least one threshold and at least one factor used to perform network slicing, based on the at least one issues identified.
