Abstract
Methods and systems allowing a plurality of computer nodes to communicate using weighted transmission paths are provided. A load balancer distributes packets across weighted transmission paths according to transmission path quality, which is monitored and updated from time to time. As transmission quality on a specific transmission path decreases, the weight assigned to that transmission path is reduced. Similarly, weights may be increased if transmission quality improves. The weights assigned to various transmission paths may correspond to a relative number of packets to be transmitted on each respective transmission path. The transmission path for each packet can be selected based on the weights of the various transmission paths. Using weights based on transmission quality, transmission paths with higher transmission quality are used more often than transmission paths with lower transmission quality, resulting in more efficient communications.
