Virtualized network device failure detection

A computer implemented method, comprising:

• identifying a statistical model using historical data and at least one processor, the historical data being for network traffic handled by a primary virtualized device during a time frame and the statistical model containing a functional state baseline representing a functional state of the primary virtualized device handling the network traffic during the time frame;
• and
• monitoring the functional state of the primary virtualized device using a hypervisor configured for:
• calculating a network traffic metric for current network traffic transmitted through a network layer of the hypervisor and handled by the primary virtualized device, using the at least one processor;
• comparing the network traffic metric for current network traffic handled by the primary virtualized device with a data point in the statistical model corresponding to the network traffic metric and the time frame for the network traffic metric in order to monitor the functional state of the primary virtualized device using the hypervisor and the at least one processor;
• and
• determining, based on a result of the comparing, that the primary virtualized device is in a non-functional state, using the at least one processor.

A system comprising:

• at least one processor;
• a memory device including instructions that, when executed by the at least one processor, cause the system to:
• generate a statistical model using historical data and the at least one processor, the statistical model containing a functional state baseline representing a functional state of a primary virtualized network device and the historical data being for previous network traffic that has been handled by the primary virtualized network device included in a virtual network during a time frame;
• add a deviation to the functional state baseline resulting in increasing a tolerance of the functional state baseline;
• monitor the functional state of the primary virtualized network device using a hypervisor configured to (i) calculate network traffic metrics for current network traffic transmitted through a network layer of the hypervisor and handled by the primary virtualized network device, and (ii) compare the network traffic metrics for the current network traffic handled by the primary virtualized network device with data points in the statistical model corresponding to the network traffic metrics;
• determine that the primary virtualized network device is in a non-functional state;
• and
• reassign a virtual network interface from the primary virtualized network device to a secondary virtualized network device as a result of having detected that the primary virtualized network device is in the non-functional state.
