Patent number: 10200114Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.Type: GrantFiled: September 26, 2017Date of Patent: February 5, 2019Assignee: VIASAT, INC.Inventors: Kenneth V.

Patent number: 10178033Abstract: Embodiments provide a virtual queue management system within the cluster of gateways. When a network message arrives at the gateway cluster, it is processed by one of the gateways within the cluster. The gateway that is processing the network message obtains identifying parameters. The identifying parameters can include, but are not limited to, an Internet Protocol (IP) address, a port number, and/or an HTTP command. The gateway creates a virtual queue identifier based on the obtained identifying parameters. The first gateway to receive a network message with a given virtual queue identifier assumes the role of virtual queue manager for that virtual queue. The virtual queue manager gateway informs other gateways within the cluster of the proper sequence for sending network messages to the server such that messages are transmitted to the server in the proper temporal order.Type: GrantFiled: April 11, 2017Date of Patent: January 8, 2019Assignee: International Business Machines CorporationInventors: John C.
