  • Patent number: 11398975
    Abstract: Described in example embodiments herein are methods and systems for implementing sending packets from a first network node to a second network node. Packets belonging to the same session may be sent through the same or different tunnels. The second network node processes packets belonging to the same session using the same core. In accordance with an example embodiment, the first network node informs the second network code the core to process the packets. Optionally, selection of core at the second network node is assisted by a core identity created by the first network based on the session. The core identity may be stored in the header or payload of the packets. In an example embodiment, the second network determines the core for processing packet belonging to the same session.

  • Publication number: 20220224779
    Abstract: The present disclosure provides systems and methods which increase the throughput of a TCP-based communication between a first network node and a second network node. First, the first network node sent a first plurality of TCP segments to the second network node. Second, when the second network node receives a second plurality of TCP segments, which is all or part of the first plurality of the TCP segments, the second network node responds by sending one or more TCP acknowledgements to the first network node with the last sequence number of a last segment among all TCP segment within the second plurality of TCP segments. The present disclosure are able to increase the throughput of a TCP connection while decreasing its reliability.

  • Publication number: 20220103306
    Abstract: The present invention discloses methods and systems for managing an error correction mode at a first communications router. The first communication router transmits data packets to a second communications router and stores the first data packet in a local storage medium. When a delay inquiry message is received from the second communications router, the first communications router activates the error correction mode. When the error correction mode is activated, the first data packet is retransmitted to the second communications router and an error correction packet corresponding to the first data packet is also transmitted. When a back-to-normal message is received from the second communications router, the first communications router deactivates the error correction mode. The back-to-normal message indicates that the first communications router no longer needs to be in error correction mode.

  • Patent number: 11245546
    Abstract: The present invention relates to methods and systems for transmitting and receiving data packets between a first network node and a second network node through a bonded connection. At the first network node, a data packet, a session identification of the data packet and a time value of the data packet are encapsulated in an encapsulating packet. The first network node sends the encapsulating packet from the first network node to the second network node through the bonded connection. The second network node then stores the encapsulating packet after receiving it and determines an expiration time of the encapsulating packet. When the expiration time of the encapsulating packet expired, the second network node dequeues the encapsulating packet and forwards the data packet according to destination of the data packet.

  • Patent number: 11076000
    Abstract: The present invention discloses methods and systems for transmitting a received packet at a first network node through an aggregated connection. The first network node determines session information of the received packet and determines whether a new tunnel needs to be selected for transmitting the received packet. When a new tunnel needs to be selected, a hash result is determined. The hash result is substantially based on the session information and the number of available tunnels. A first tunnel is determined for transmitting the received packet according to the hash result. The session information and tunnel ID of the first tunnel is then stored in a first database. The received packet is transmitted through the first tunnel. When a new tunnel need not be selected, a lookup is performed to determine a tunnel ID substantially based on the session information. The received packet is transmitted through the determined tunnel.

  • Patent number: 11005685
    Abstract: A method and a first communications router for transmitting data packets to a second communications router by establishing an aggregated end-to-end connection with the second communications router. The aggregated end-to-end connection comprises a plurality of established end-to-end connections. Data packets are transmitted through a first established end-to-end connection when a first condition is satisfied, and through a second established end-to-end connection when a second condition is satisfied. The first and second established end-to-end connections belong to the aggregated end-to-end connection. The first communications router comprises a plurality of network interfaces.

  • Patent number: 10958469
    Abstract: The present disclosure provides for devices, systems, and methods which optimize throughput of bonded connections over multiple variable bandwidth logical paths by adjusting a tunnel bandwidth weighting schema during a data transfer session in response to a change in bandwidth capabilities of one or more tunnels. By making such adjustments, embodiments of the present invention are able to optimize the bandwidth potential of multiple connections being used in a session, while minimizing the adverse consequences of reduced bandwidth issues which may occur during the data transfer session.

  • Publication number: 20210058271
    Abstract: The present invention discloses methods and systems for sending information packets from a first network node to a second network node. An aggregated tunnel is established between the first network node and the second network node. An information packet is determined whether to be sent according to profile condition(s) of the aggregated tunnel and then according to a selected policy. When a selected policy is selected and the information packet is sent through a tunnel according to the selected policy. When no policy is selected, the information packet is sent through one of a first group of tunnels. When no profile is selected, the information packet is sent through a network interface of the first network node.

  • Patent number: 10873477
    Abstract: The present invention discloses methods and systems for sending information packets through a plurality of aggregated tunnels established between a first network node and a second network node. Each aggregated tunnel is comprised of at least one tunnel and at least one of the two network nodes has at least two network interfaces. In order to send an information packet, it is first determined whether the information packet satisfies at least one policy. If at least one policy is satisfied, the information packet is sent using an aggregated tunnel corresponding to the satisfied policy. If no policy is satisfied, the information packet is sent using a network interface of the first node without using an aggregated tunnel.

  • Publication number: 20200351961
    Abstract: A method and system for a first node to transmit packets to a second none, comprising receiving a packet from a local area network (LAN) interface, inspecting the packet; determining whether the packet satisfies at least one packet condition; transmitting the packet through a predefined tunnel if the packet satisfies the at least one packet condition; transmitting the packet through a second tunnel if the packet does not satisfy the at least one packet condition. The predefined tunnel is a first tunnel and is established before the packet is received by the first node. The second tunnel belongs to a first tunnel group or a second tunnel group. The first tunnel, the second tunnel and other tunnels may together form an aggregated connection. Further, the use of predefined tunnel may be based on whether the packets satisfy a session condition.

  • Patent number: 10805219
    Abstract: Methods and systems for transmitting data packets through a selected connection that the first data packet of a data session satisfies a match condition. The match condition is received through a user interface. When data packets of the data session are received, the data packets will then be transmitted through a selected connection. The selected connection is selected from connections based on a connection selection criteria. Further differentiated services code point (DSCP) of first data packet is changed when sent by a computing device. After a network node receives the first data packet, then resets the DSCP value before sending the first data packet.
