Patent number: 12289238Abstract: 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.Type: GrantFiled: February 3, 2021Date of Patent: April 29, 2025Assignee: Viasat, Inc.Inventors: Jae Won Chung, Ankitkumar N. Patel, Girish Chandran, Anil K. Agarwal

Patent number: 12250152Abstract: Disclosed are systems and methods for steering network traffic over different access networks based on a classification of the network traffic. A first access network provides a first network path between a client device and a destination network and a second access network provides a second network path between the client device and the destination network. The access networks have different characteristics, such as latency or available bandwidth. A traffic classifier receives network messages and assigns classifications to the received network messages. A policy enforcer determines routes for individual network messages. The determined route is based at least in part on the classification assigned by the traffic classifier.Type: GrantFiled: June 16, 2023Date of Patent: March 11, 2025Assignee: VIASAT, INC.Inventor: Girish Chandran

Publication number: 20240421896Abstract: 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.Type: ApplicationFiled: March 22, 2024Publication date: December 19, 2024Inventors: Michael Foxworthy, Girish Chandran, Jason Lau

Patent number: 12114397Abstract: 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.Type: GrantFiled: June 8, 2023Date of Patent: October 8, 2024Assignee: VIASAT, INC.Inventors: James N. Esserman, Daniel M. Newman, Girish Chandran, Mark D. Dankberg, Jae Won Chung
