US Classification:

370392

Abstract:

Methods and systems for implementing acceleration through a packet encapsulation protocol tunnel, are described. The method includes establishing a packet encapsulation protocol tunnel between a first network endpoint and a second network endpoint, sending packets with a packet encapsulation protocol tunnel header from the first network endpoint to the second network endpoint, and removing the packet encapsulation protocol tunnel headers from the packets. The method further includes storing the packet encapsulation protocol tunnel headers in a storage memory, performing acceleration on the packets, and retrieving the packet encapsulation protocol tunnel headers from the storage memory. Further, the method includes replacing the packet encapsulation protocol tunnel headers on the packets, and sending the packets with the packet encapsulation protocol tunnel headers through the packet encapsulation protocol tunnel to the second endpoint.

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.

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.

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 (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 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.

Abstract:

Systems and methods for providing mobility across satellite beams, are described. The system includes a first core node, a second core node in communication with the first core node at layer-2 of the OSI model (L2), and a first gateway in communication, at L2, with the first core, the first gateway configured to provide access to a first spot beam at a first location. The system further includes a second gateway in communication, at L2, with the second core node, the second gateway configure to provide access to a second spot beam at a second location, and a mobile device, at the first location, in communication with the first gateway via the first spot beam, wherein the mobile device is assigned an IP address by the first core node. The mobile device moves from the first location to the second location. Further, the first gateway, in response to the mobile device moving from the first location to the second location, notifies the second gateway, through the first core node and the second core node, that the mobile device is moving to the second location, and transmits the session information to the second gateway, and the second gateway, in response to the notification, maintains connectivity with the mobile device using the IP address.
