First Claim
1. A satellite communication system, comprising:
- a first core node of a ground segment network, the first core node comprising at least one switch, a first service processor, and an interface in communication with a second network that is external to the ground segment network;
a first gateway comprising a first satellite modem termination system and a first network interface coupled with the at least one switch of the first core node, the first gateway in communication with a satellite configured to relay first signals between the first gateway and a first plurality of user terminals within a first spot beam of the satellite, the first gateway utilizing at least one service provided by the first service processor of the first core node for providing communication services between the first plurality of user terminals and an entity within the second network; and
a second gateway coupled with the at least one switch of the first core node, the second gateway in communication with the satellite, the satellite configured to relay second signals between the second gateway and a second plurality of user terminals within a second spot beam of the satellite, the second gateway utilizing the at least one service provided by the at least one service processor of the first core node for providing communication services between the second plurality of user terminals and the entity within the second network.

Abstract
Methods, systems, and apparatuses for providing layer-2 connectivity through a non-routed ground segment network, are described. A system includes a non-autonomous gateway in communication with a satellite configured to relay data packets. The non-autonomous gateway is configured to receive the data packets from the satellite at layer-1 (L1) of the OSI-model, generate a plurality of virtual tagging tuples within the layer-2 packet headers of the plurality of data packets. The non-autonomous gateway is further configured to transmit, at layer-2 (L2) of the OSI-model, the virtually tagged data packets. Each of the packets may include a virtual tagging tuple and an entity destination. The system further includes a L2 switch in communication with the non-autonomous gateway. The L2 switch may be configured to receive the data packets and transmit the data packets to the entity based on the virtual tuples associated with each of the data packets.
