Title: LAYER-2 CONNECTIVITY FROM SWITCH TO ACCESS NODE/GATEWAY
Abstract:
Methods, systems, and apparatuses for providing layer-2 connectivity through a non-routed ground segment network, are described. A system includes a satellite configured to transmit data packets. The system further includes a non-autonomous gateway in communication with the satellite. The non-autonomous gateway is configured to receive the data packets from the satellite at layer-1 (Ll) 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 including 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 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. The virtual tagging tuple may be implemented as a VLAN tag according to the 802. IQ standard.
