Abstract

A satellite networking system is described. The system includes a first satellite, a second satellite, and a core network. The core node is configured to provide a plurality of services. The system further includes a first gateway in communication with the first satellite and the core network, and a second gateway in communication with the second satellite and the core network. The first satellite is configured to share the plurality of services with the second satellite through the first and second gateways.

Claims

1. A satellite networking system comprising:

a first satellite;

a second satellite;

a core network configured to provide a plurality of services;

a first gateway in communication with the first satellite and the core network; and

a second gateway in communication with the second satellite and the core network,

wherein the first satellite is configured to share the plurality of services with the second satellite through the first and second gateways.

2. A satellite networking system as in claim 1, wherein the plurality of services comprise one or more of the following:

shared resources, redundancy services, customer services, and mobility services.

3. A satellite networking system as in claim 2, wherein the shared resources comprise one or more of the following:

acceleration resources, provisioning resources, authentication resources, authorization resources, and certification resources.

4. A satellite networking system as in claim 2, wherein the customer services comprise one of more of the following:

2-way residential broadband service, enterprise services, and wholesale services.

5. A satellite networking system as in claim 1, wherein communication between the first gateway and the core network is at layer-2 of the OSI model (L2).

6. A satellite networking system as in claim 5, wherein communication between the second gateway and the core network is at L2.

7. A satellite networking system as in claim 6, wherein the networking system comprises L2 connectivity to the network system'"'"'s edge.

8. A satellite networking system as in claim 1, further comprising a client device in communication with the first satellite, wherein the client device is provided an IP address.

9. A satellite networking system as in claim 8, wherein the client device moves from coverage of the first satellite to coverage of the second satellite, wherein during the move the client device maintains the same IP address.

10. A satellite networking system as in claim 1, wherein the core network comprises one or more core nodes connected by a private network.

11. A satellite networking system as in claim 10, wherein the private network carries traffic for one or more subscribers.

17. A satellite networking system as in claim 1, wherein the plurality of services comprise one or more of the following:
