Abstract
A technique includes transmitting traffic to a destination via at least a first path of a plurality of paths to the destination, each path including one or more path segments, a plurality of ports being associated with each path segment, receiving port congestion information for each of the ports, determining whether each of the plurality of path segments is congested based on the port congestion information, making a first determination that the first path is congested and that one or more second paths are not congested, each of the paths is determined to be congested if one or more path segments of the path is congested, and re-routing at least some traffic directed to the destination from the congested first path to one or more of the uncongested second paths in response to the first determination.
