Abstract: A network controller maintains network availability between a pair of endpoints. The controller detects a topology of a computer network connecting endpoints. The controller determines a metric of availability between a first endpoint and a second endpoint. The metric of availability is based on non-overlapping paths between the first endpoint and the second endpoint. Responsive to a determination that the metric of availability satisfies a predetermined criterion, the controller adjusts a path between the first endpoint and the second endpoint.
