A method is provided for selecting a transmit link in a bonding group. Traffic is distributed to the links based on a selection method. Typical selection methods for bonded links of the same type include round robin or weighted round robin. A method is disclosed including selecting from among bonded links of different types based on link priority or link-to-group backpressure, sometimes both, and in some cases also based on traffic class. Link priority is based on the reliability, or quality, of the link. Adding link priority, and optionally traffic class, into the selection method allows high priority traffic to be always transported over high quality links. Also, considering the link-to-group backpressure, such as based on congestion status of operational links, or active links, will help avoid link congestion. The method is relevant to Quality of Service (QoS) implementation in transportation systems used for mobile backhaul or carrier access networks.
