Abstract: Approaches are disclosed for providing path diversity in a data transmission network. A primary transmission path can be selected through a network, such as a backbone network, based on factors such as cost of transmission. At least one waypoint can be selected that is to be included in a secondary transmission path. The waypoint(s) can be selected such that the secondary transmission path will have few, if any, network components in common with the primary transmission path, providing significant path diversity. The waypoint(s) can be selected based on a cost ratio or other such factor. In the event of a failure of transmission of a data packet over one of the transmission paths, a second transmission attempt can be performed using the same path or the other transmission path, or both.
