Predictive routing-based policy adjustments in software-defined networks

An apparatus, comprising:

• one or more network interfaces;
• a processor coupled to the one or more network interfaces and configured to execute one or more processes;
• and
• a memory configured to store a process that is executable by the processor, the process when executed configured to:
• obtain routing forecasts for a software defined network, at least one of the routing forecasts predicting a link failure or a service level agreement (SLA) violation in the software defined network;
• split a particular routing policy for the software defined network into two or more routing policies, based on the routing forecasts;
• make, based on an assessment of whether the predicted link failure or SLA violation actually occurred in the software defined network, an evaluation as to whether the two or more routing policies should be reverted back into the particular routing policy;
• and
• send, to a user interface, data indicative of the particular routing policy that was split into the two or more routing policies and the evaluation as to whether the two or more routing policies should be reverted back into the particular routing policy.

A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:

• obtaining, by the device, routing forecasts for a software defined network, at least one of the routing forecasts predicting a link failure or a service level agreement (SLA) violation in the software defined network;
• splitting, by the device, a particular routing policy for the software defined network into two or more routing policies, based on the routing forecasts;
• making, by the device and based on an assessment of whether the predicted link failure or SLA violation actually occurred in the software defined network, an evaluation as to whether the two or more routing policies should be reverted back into the particular routing policy;
• and
• sending, by the device and to a user interface, data indicative of the particular routing policy that was split into the two or more routing policies and the evaluation as to whether the two or more routing policies should be reverted back into the particular routing policy.
