Access node/gateway to access node/gateway layer-2 connectivity (end-to-end)
First Claim
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 bent pipe satellite configured to receive signals from one or more user terminals and to relay the signals at layer-1 of the OSI-model (L1) to a first non-autonomous gateway configured for processing primarily below layer-3 of the OSI-model (L3);
wherein the first non-autonomous gateway is configured to demodulate the signals relayed from the bent pipe satellite and to generate from the demodulated signals data packets having packet headers for layer-2 of the OSI-model (L2), wherein the packet headers contain virtual tagging tuples, each data packet including a virtual tagging tuple;
a ground-based L2 switch in communication with the first non-autonomous gateway, the ground-based L2 switch configured to receive the data packets and to transmit the data packets; and
a second non-autonomous gateway in communication with the ground-based L2 switch, the second non-autonomous gateway configured to receive the data packets from the ground-based L2 switch and to transmit the data packets to an entity based on each of the virtual tagging tuples associated with each of the data packets.

Abstract
Systems, methods, and apparatus for providing end-to-end L2 connectivity, are described. The system includes satellites configured to transmit data packets. The system further includes a first non-autonomous gateway in communication with the satellites. The first non-autonomous gateway is configured to receive the data packets from the satellites at L1, generate virtual tagging tuples within L2 packet headers of the data packets, and transmit the data packets each including a virtual tagging tuple. The system further includes a L2 switch in communication with the first non-autonomous gateway. The L2 switch is configured to receive the virtually tagged data packets and transmit the virtually tagged data packets. Further, the system includes a second non-autonomous gateway in communication with the L2 switch. The second non-autonomous gateway configured to receive the virtually tagged data packets and transmit the virtually tagged data packets to an entity based on the virtual tagging tuple associated with each of the virtually tagged packets.

10. A method of providing end-to-end layer-2 connectivity throughout a non-routed ground segment network connected to one or more satellites, the method comprising:
-
receiving, by a bent pipe satellite, signals from one or more user terminals; relaying, by the bent pipe satellite at layer-1 of the OSI-model (L1), the signals to a first non-autonomous gateway configured for processing primarily below layer-3 of the OSI-model (L3); demodulating, by the first non-autonomous gateway, the signals relayed from the bent pipe satellite; generating, by the first non-autonomous gateway, from the demodulated signals data packets having packet headers for layer-2 of the OSI-model (L2), wherein the packet headers contain virtual tagging tuples, wherein each data packet includes a virtual tagging tuple; receiving, at a ground-based L2 switch in communication with the first non-autonomous gateway, the data packets; transmitting, by the ground-based L2 switch, the data packets; receiving, by a second non-autonomous gateway in communication with the ground-based L2 switch, the data packets; and transmitting, by the second non-autonomous gateway, the data packets to an entity based on each of the virtual tagging tuples associated with each of the data packets. - View Dependent Claims (11, 12, 13, 14, 15)
