1. A system for providing end-to-end layer-2 connectivity throughout a non-routed ground segment network connected to one or more satellites, the system comprising: a first non-autonomous gateway configured for processing primarily below layer-3 of the OSI-model (L3), the first non-autonomous gateway in communication with a bent pipe satellite that receives signals from one or more user terminals and relays the signals to the first non-autonomous gateway at layer-1 of the OSI-model (L1), the first non -autonomous gateway comprising: a satellite modem termination system (SMTS) that demodulates the signals relayed from the bent pipe satellite and generates from the demodulated signals, a plurality of data packets having packet headers for layer-2 of the OSI-model (L2); and a switch coupled with the SMTS that receives the plurality of data packets from the SMTS and adds virtual tagging tuples to the packet headers for each data packet of a subset of the plurality of data packets; wherein the switch of the first non-autonomous gateway sends, via a ground-based L2 switch in communication with the first non-autonomous gateway, the subset of the plurality of data packets to a second non-autonomous gateway for transmission to an entity based on the virtual tagging tuples associated with each of the subset of the plurality of data packets.
