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 (LI) 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： Methods, apparatuses, and systems for providing layer-2 extension services through a non-routed ground segment network, are described. The method includes providing a Layer-2 (L2) interface between a node of the non-routed ground segment network and a service provider, assigning a virtual tagging tuple to the service provider and receiving service provider traffic at a node of the non-routed ground segment network. The method further includes tagging the service provider traffic with the virtual tagging tuple, and switching the tagged service provider traffic through the non-routed ground segment network according to the virtual tagging tuple.

摘要： Methods, systems, and devices for communications are described. One or more flows between a node and one or more other nodes in a communication network may be monitored over a time period. During the monitoring, it may be identified that, during a subset of the time period, communications over at least one of the flows were restricted by the communication network based on receiving at least one indicator of congestion for the at least one flow. A quantity of traffic communicated over the one or more flows during the subset of the time period may then be determined, and respective flow rates of the one or more flows may be obtained. The obtained flow rates may be used to calculate a data rate of one or more connections between the node and the one or more other nodes.
