摘要： Methods and systems for individual forward-link and return-link policies for network communication are disclosed. In some aspects, the individual forward-link and return-link policies define how data is routed over a plurality of access networks between a client-side enforcement unit and a provider-side enforcement unit. In some aspects, the individual policies may be based on metrics collected by the client-side and provider-side enforcement units, which may be positioned on each end of one or more access networks.

摘要： Methods, systems, and apparatuses for providing layer-2 connectivity through a non-routed ground segment network, are described. A system includes a non-autonomous gateway in communication with a satellite configured to relay data packets. 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 may include 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 may be 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.

摘要： 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 transmit 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.

摘要： Described herein are systems and methods that dynamically manage network traffic for individual subscribers based on past and current data usage rates. The disclosed systems and methods operate to control data traffic for a group of subscribers that share a common access network or that share a common access link to an access network. Prior to an individual subscriber reaching their data plan limit, the disclosed systems and methods track individual subscribers' past and current data rates and manage individual subscribers' current usage rates so that each subscriber's continually or periodically updating past usage rate stays within a provisioning rate for the group. This can improve user experience because rather than waiting until a subscriber has reached their plan data limit to impose strict data usage restrictions, the disclosed systems and methods use modest restrictions continuously or intermittently during the plan period.
