CORE-BASED SATELLITE NETWORK ARCHITECTURE
First Claim
1. A satellite networking system comprising:
- a plurality of satellite gateways in communication with a plurality of subscribers over one or more satellite communication networks, the plurality of satellite gateways configured to send network communications to the plurality of subscribers and receive network communications from the plurality of subscribers;
a first core node in communication with at least one of the plurality of satellite gateways, the first core node configured to provide a plurality of networking services, at layer-2 of the OSI model (L2), to a first subset of the plurality of subscribers; and
a second core node in communication, at L2, with at least one of the plurality of satellite gateways and the first core node, the second core node configured to provide the plurality of networking services, at layer-2 of the OSI model, to a second subset of the plurality of subscribers,wherein in response to failure of at least one of the plurality of networking services in the first core node, the second core node providing the at least one of the plurality of services to the first subset of the plurality of subscribers.

Abstract
Systems and methods for implementing a satellite network, are described. The system includes satellite gateways in communication with subscribers over a satellite communication network. The satellite gateways send network communications to the subscribers and receive network communications from the subscribers. The system further includes a first core node in communication with at least one of the satellite gateways. The first core node provides networking services, at L2, to a first subset of subscribers. The system further includes a second core node in communication, at L2, with one of the satellite gateways and the first core node. The second core node provides the networking services, at layer-2 of the OSI model, to a second subset of the subscribers. In response to failure of at least one of the networking services in the first core node, the second core node providing the at least one of the services to the first subset of the subscribers.

9. A satellite networking system comprising:
-
a first core node in communication, at layer-2 of the OSI model (L2), with a first satellite gateway; a second core node in communication, at L2, with a second satellite gateway and the first core node; and a peering node in communication, at L2, with the first satellite gateway, wherein the peering node is configured to provide content or services at the first satellite gateway, and wherein the peering node is further configured to provide content or services at any one of the first code node, the second core node, and the second satellite gateway. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of implementing a redundant core node architecture in a satellite communication network, the method comprising:
-
providing, at a first core node, a plurality of services, at layer-2 of the OSI model (L2), to a first plurality of subscribers through a first satellite gateway; providing, at a second core node, the services, at L2, to a second plurality of subscribers through a second satellite gateway and the first core node; receiving, at the second core node, a failure notification of at least one of the plurality of services provided by the first core node; in response to the failure notification, providing, by the second core node, the at least one of the plurality of services to the first plurality of subscribers. - View Dependent Claims (16, 17, 18, 19)

20. A computer-readable medium having sets of instructions stored thereon which, when executed by one or more computers, cause the one or more computers to:
-
provide, at a first core node, a plurality of services, at layer-2 of the OSI model (L2), to a first plurality of subscribers through a first satellite gateway; provide, at a second core node, the services, at L2, to a second plurality of subscribers through a second satellite gateway and the first core node; receive, at the second core node, a failure notification of at least one of the plurality of services provided by the first core node; in response to the failure notification, provide, by the second core node, the at least one of the plurality of services to the first plurality of subscribers.
