Abstract
An adaptive router anticipates possible future congestion and enables selection of an alternative route before the congestion occurs, thereby avoiding the congestion. The adaptive router may use a primary route until it predicts congestion will occur. The adaptive router measures packet traffic volume, such as flit volume, on a primary network interface to anticipate the congestion. The adaptive router maintains a trailing sum of the number of flits handled by the primary network interface over a trailing time period. If the sum exceeds a threshold value, the adaptive router assumes the route will become congested, and the adaptive router enables considering routing future packets, or at least the current packet, over possible secondary routes.
