Context-aware virtualized control decision support system for providing quality of experience assurance for internet protocol streaming video services

A method comprising:

• determining, by a quality of experience assurance analyzer of a quality of experience assurance decision support system, whether quality of experience assurance analytics indicate that a quality of experience associated with a service provided by a virtual machine has been degraded;
• in response to determining that the quality of experience associated with the service provided by the virtual machine has been degraded, constructing, via the quality of experience assurance analyzer, a fault correlation information model to be utilized for root cause analysis to determine a root cause of the quality of experience associated with the service provided by the virtual machine being degraded;
• determining, by the quality of experience assurance analyzer, based upon the fault correlation information model, whether the root cause of the quality of experience associated with the service provided by the virtual machine being degraded is due to a capacity reduction, wherein determining, based upon the fault correlation information model, whether the root cause of the quality of experience associated with the service provided by the virtual machine being degraded is due to a capacity reduction comprises determining whether a number of suspend events associated with the virtual machine entering into a suspend state equals a number of threshold-crossing alarm events associated with a throughput of the service provided by the virtual machine being lower than a playback rate;
• and
• in response to determining that the root cause of the quality of experience associated with the service provided by the virtual machine being degraded is due to a capacity reduction, identifying, by the quality of experience assurance analyzer, a new network resource for capacity reallocation to accommodate a virtual machine migration.

A quality of experience assurance decision support system comprising:

• a processor;
• and
• a memory that stores a plurality of modules comprising instructions that, when executed by the processor, cause the quality of experience assurance decision support system to perform operations comprising
• determining, by a quality of experience assurance analyzer module of the plurality of modules, whether quality of experience assurance analytics indicate that a quality of experience associated with a service provided by a virtual machine has been degraded,
• in response to determining that the quality of experience associated with the service provided by the virtual machine has been degraded, constructing, via the quality of experience assurance analyzer module, a fault correlation information model to be utilized for root cause analysis to determine a root cause of the quality of experience associated with the service provided by the virtual machine being degraded,
• determining, by the quality of experience assurance analyzer module, based upon the fault correlation information model, whether the root cause of the quality of experience associated with the service provided by the virtual machine being degraded is due to a capacity reduction, wherein determining, based upon the fault correlation information model, whether the root cause of the quality of experience associated with the service provided by the virtual machine being degraded is due to a capacity reduction comprises determining whether a number of suspend events associated with the virtual machine entering into a suspend state equals a number of threshold-crossing alarm events associated with a throughput of the service provided by the virtual machine being lower than a playback rate, and
