Quality of service manager for network slices of a network

A device, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• receive information identifying a network slice template associated with a network slice of a network,
• wherein the network slice template indicates how to instantiate the network slice, and
• wherein the network slice is instantiated according to the network slice template;
• determine, and from the network slice template, a quality of service (QoS) profile for the network slice, wherein the QoS profile includes a set of performance metrics for providing a service;
• monitor performance of the network slice in association with the QoS profile;
• store, based on monitoring the performance of the network slice and in a real-time slice information table stored by the device, a set of performance indicates and the network slice template;
• identify, based on monitoring the performance of the network slice and in an expected QoS data table stored by the device, the network slice template a set of QoS parameters assigned to the set of performance metrics;
• determine, based on comparing a performance indicator, of the set of performance indicators, to a corresponding performance metric of the set of corresponding performance metrics, that the performance indicator is outside of a threshold range of the corresponding performance metric;
• determine, based on determining that the performance indicator is outside of the threshold range, a slice modification to the network slice;
• and
• provide the slice modification to a network slice orchestrator to cause the network slice orchestrator to configure a resource, of the network, according to the slice modification and the network slice template.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
• receive information identifying a network slice template associated with a network slice of a network,
• the network slice template indicates how to instantiate the network slice, and
• wherein the network slice is instantiated according to the network slice template;
• determine, from the network slice template, a quality of service (QoS) profile for the network slice, wherein the QoS profile includes a set of performance metrics for providing a service;
• monitor performance of the network slice in association with the QoS Profile;
• store, based on monitoring the performance of the network slice and in a real-time slice information table stored by the device, the network slice template and a set of performance indicators;
• identify, based on monitoring the performance of the network slice and in an expected QoS data table stored by the device, the network slice template and a set of QoS parameters assigned to the set of performance metrics;
• determine, based on comparing a performance indicator, of the set of performance indicators, to a corresponding performance metric of the set of corresponding performance metrics, that the performance indicator is outside of a threshold range of the corresponding performance metric;
• determine, based on the performance indicator being outside of a threshold range of the performance metric, a slice modification to the instantiation;
• and
• cause a network slice orchestrator to configure a resource of the instantiation according to the slice modification.
