Techniques are described that increase the reliability and quality of data transmissions of computer networks. The techniques provide for the generation of at least two duplicate data flows for carrying data in a computer network. The duplicate data flows are transmitted to a receiving device along paths within one or more intermediate networks. In addition, network devices, such as routers or switches within the network, for example, may cooperate to select paths for the data flows that have reduced or minimal common network elements. The network devices may share “fate-sharing” information that relates groups of network elements according to common characteristics, attributes or shared resources, e.g., a shared power supply, close proximity, common physical interface, for the purposes of facilitating selection of independent paths.
