Abstract: Embodiments provide techniques for providing return-link routing in a hybrid communications network that includes a number of different networks having different characteristics. User terminal routing systems (UTRSs) provide interfaces between local user networks and the multiple communications networks of the hybrid network. Each UTRS can include a routing table having stored mappings that are populated according to forward-link communications (implicitly or explicitly), each associating a respective one of a plurality of routing table entries with one of the communications networks. When a UTRS receives return-link data from its respective local user network, the received data indicates a destination node. The UTRS can determine which of the stored mappings corresponds to the destination node and can route the received return-link data over a selected one of the communications networks in accordance with the identified one of the mappings.
