Patent number: 11824747Abstract: Systems, methods, and apparatus, including computer-readable media, for enhanced network communication using multiple network connections. In some implementations, a networking apparatus concurrently maintains connectivity to a network through each of multiple network transports. The networking apparatus receives one or more packets to be transmitted over the network and classifies the one or more packets to determine a class of service. The networking apparatus selects one of the multiple network transports to transmit the one or more packets based on (i) the class of service for the one or more packets and (ii) measures of expected latency for transmission of the one or more packets over the respective multiple network transports. The networking apparatus transmits the one or more packets using the selected network transport.Type: GrantFiled: June 10, 2022Date of Patent: November 21, 2023Assignee: Hughes Network Systems, LLCInventor: Douglas Dillon

Patent number: 10644978Abstract: The technology described herein is directed to configuring the rate limiters of network devices based on latency measurements. The rate limiters are configured based on latency measurements such that the network traffic is transmitted and/or received at a maximum possible rate while minimizing/preventing the loss of traffic prioritization. To this end, a latency increase, estimated rate decrease algorithm may be implemented whereby the percentage rate reduction of a rate limiter is based on the rate of increase in inbound latency or outbound latency measured over a predetermined period of time (e.g., over a predetermined number of latency measurements). Depending on the change of inbound latency or outbound latency of traffic on the network, a receive rate limiter or a transmit rate limiter of an edge device may be dynamically adjusted.Type: GrantFiled: November 22, 2017Date of Patent: May 5, 2020Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Douglas Dillon, Arun Athrey Chandrasekaran

Patent number: 10637782Abstract: An approach is provided whereby multiple broadband connections operate together to provide a highly available secure private networking solution. Data packets of a communications flow are received by a networking device, for transmission to a remote destination node, over a wide area data communications network. A service classification is determined for the data flow. A sequence number is generated for each data packet, where the sequence numbers indicate an order by which the data packets are received. An indication of the service classification and the sequence number is added to each data packet. For each data packet, a transport policy is determined that indicates one or more VPN tunnels through which the data packet is to be transmitted, where the determination of the VPN tunnels is based on the service classification, and wherein each VPN tunnel is carried over a respective WAN transport of the wide area data network.Type: GrantFiled: February 10, 2017Date of Patent: April 28, 2020Assignee: Hughes Network Systems, LLCInventors: Douglas Dillon, Gaurav Sabharwal

Patent number: 10277716Abstract: An approach for multi-stream data compression comprises receiving packets of a data stream, wherein the packets comprise respective packets of source data streams compressed on an aggregate basis and in a successive order. A one of the packets is decompressed, and a determination is made whether the packet has been received in a proper order of succession compared to the successive order of compression. When it is determined that the packet has been received in the proper order, the packet is stored at a next location in a decompressor cache. When it is determined that the packet has not been received in the proper order, the packet is stored at a location in the decompressor cache, allowing for subsequent storage of one or more further packets in the proper order of succession, wherein the further packets were processed via the compression process before, but were received after, the one packet.Type: GrantFiled: October 25, 2016Date of Patent: April 30, 2019Assignee: Hughes Network Systems, LLCInventors: Udaya Bhaskar, Douglas Dillon

Patent number: 10178035Abstract: Systems and methods are provided for quality of service over broadband networks. A network device performs a probe transaction over a tunnel of a broadband network. Based on the probe transaction, parameters are determined reflecting tunnel performance, and, based on the parameters, target transmit and receive rates are determined for data communications over the tunnel. Based on the target transmit and receive rates, data communications to and from a first node of the network are regulated. When the tunnel comprises a peered tunnel, the regulation of received data communications comprises performing a set rate transaction with a peer second node of the network (the set rate transaction establishes a rate for data transmitted over the tunnel by the peer second node to the first node). When the tunnel comprises a peerless tunnel, the regulation of received data communications comprises shaping data traffic received by the first node over the tunnel.Type: GrantFiled: July 20, 2017Date of Patent: January 8, 2019Assignee: Hughes Network Systems, LLCInventor: Douglas Dillon

Patent number: 9832169Abstract: An approach for providing secure communication services is disclosed. A secure data tunnel from a source node to a destination node is established via a plurality of secure segments across a data communications network. A data path is established via the secure data tunnel, where the data path supports a performance enhancing mechanism that improves performance of data communications over the data path. The performance enhancing mechanism multiplexes data packet flows from the source node for transmission over the data path, and performs one or more of connection startup latency reduction, acknowledgment message spoofing, window sizing adjustment, compression and selective retransmission.Type: GrantFiled: January 26, 2015Date of Patent: November 28, 2017Assignee: Hughes Network Systems, LLCInventors: John Border, Douglas Dillon, Peter Pardee

Patent number: 9832131Abstract: Approaches for managing characteristics for inbound data communications between a first network site and a remote network site of a WAN are provided. The inbound communications are received by the first network site via a series of links of the WAN. Protocol overhead factors are determined based on overhead associated with network protocols applied to the data communications over the links. Link throughput limits are determined for the inbound data communications, wherein the throughput limits are determined based on the protocol overhead factors. The throughput limits are transmitted to the second network site for transmission of the inbound data communications from the second network site. The inbound data communications are received by a first device of the first network site via the first link, wherein the first link is between the first device and a second device serving as an exit point from a public portion of the WAN.Type: GrantFiled: January 19, 2016Date of Patent: November 28, 2017Assignee: Hughes Network Systems, LLCInventors: Shanti Swarup Vedula, Douglas Dillon, Jeffrey Biber
