  • Publication number: 20180227395
    Abstract: Methods and systems for creating protocol header to allow network device to transfer and receive layer two packets through multiple network links. One or more layer three packets are used to encapsulate layer two packets. The protocol header includes a network link identification and a tunnel sequence number. The network link identification is used to identify the network link and the tunnel sequence number is used to identify the sequence of the one or more layer three packets in a network link. A layer two packet may be encrypted first before being embedded in the one or more layer three packets.

  • Patent number: 10044521
    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: 20180167987
    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.

  • Publication number: 20180131774
    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: 9960966
    Abstract: The present invention discloses methods and systems for managing VPN tunnels. A VPN concentrator establishes a first aggregated VPN connection and a second aggregated VPN connection with a first host and a first network device respectively. When the first aggregated VPN connection comprises a first plurality of VPN tunnels, the VPN concentrator applies uplink and downlink bandwidth limits to each of the plurality of VPN tunnels. Similarly, when the second aggregated VPN connection comprise a second plurality of VPN tunnels, the VPN concentrator applies uplink and downlink bandwidth limits to each of the plurality of VPN tunnels. The first host encapsulates a first data packet in a first encapsulating packet and transmits the first encapsulating packet to a VPN concentrator using a first aggregated VPN connection.

  • Publication number: 20180109357
    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.

  • Publication number: 20180034666
    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: 9876723
    Abstract: The present invention discloses a method carried out by a first communications device for determining performance of a plurality of connections and selecting at least one first connection from the plurality of connections substantially based on performance. Data packets are then transmitted through the at least one first connection. The plurality of connections are aggregated to form an aggregated connection. The determining of performance is performed by transmitting evaluation packets through the plurality of connections. The evaluation packets are based on data packets that are received by the first communication device but have not yet been transmitted through the aggregated connection. The data packets may be designated for a host or node reachable through the aggregated connection. Alternatively, the evaluation packets may be based on predefined information when there are no data packets to be transmitted through the aggregated connection. The performance may be determined periodically.
