  • Patent number: 10721783
    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: 10693600
    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: 20200195609
    Abstract: A method and a system of restricting data packet transmission of an apparatus at a network node. The network node, during a first time period, updates a whitelist and does not restrict data packet transmission according to the whitelist. After the first time period, the network node determines corresponding destination address of each of the data packets and allows the data packets to be sent to the corresponding destination address if a criteria is satisfactory. The network node does not allow the data packets to be sent to the corresponding destination address if the criteria is not satisfactory. The whitelist is comprised of at least one destination address. The criteria is based on the at least one destination address. The whitelist list is stored in non-transitory computer readable storage medium in the network node.

  • Publication number: 20200068027
    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.

  • Publication number: 20200052926
    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.

  • Publication number: 20200021671
    Abstract: A method and a system for updating a first whitelist at a network node. The network node receives data packets from an Internet of Things (IoT) device and determines a predetermined identifier for the IoT device. The network node then determines whether the predetermined identifier is in the first whitelist. When the predetermined identifier is not in the first whitelist, the network node starts a first time period. When the predetermined identified is on the first whitelist, the network node determines whether the data packets are received within the first time period. When the data packets are received within the first time period, the network node identifies destination addresses of the data packets and updates the first whitelist based on the destination addresses and the predetermined identifier. The updated first whitelist is stored in non-transitory computer readable storage medium in the network node.

  • Patent number: 10511522
    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.

  • Publication number: 20190268181
    Abstract: Methods and systems for transmitting and receiving data between a first node and a second node through a first tunnel group and a second tunnel group respectively. The first node transmits data to the second node mainly through a first tunnel group and receives data from the second node mainly through a second tunnel group. In some embodiments, the first node receives first IP packets from one of its LAN interfaces and then transmits encapsulated first IP packets and then are transmitted mainly through a first one or more WAN interfaces to the second node. The first node receives encapsulated second IP packets mainly from the second node through a second one or more of its WAN interfaces. Second IP packets are then decapsulated and transmitted through one of the LAN interfaces of the first node.

  • Publication number: 20190190834
    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.
