摘要： 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.

摘要： A method carried out by 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 which are classified into a first group and at least one non-first group of established end-to-end connection(s). The first group of established end-to-end connection(s) satisfy all of one or more conditions and the at least one non-first group of established end-to-end connection(s) do not satisfy all of the one or more conditions. Data packets are transmitted through the first group of established end-to-end connection(s) and the at least one non-first group of established end-to-end connection(s), although, it is preferred to transmit data packets through the first group of established end-to-end connection(s). The present invention further comprises a method and system for determining whether each of the established end-to-end connections of an aggregated end-to-end connection belongs to a first group of established end-to-end connection(s) or at least one non-first group of established end-to-end connection(s) and determining whether data packets are first type data packets. The first type data packets are transmitted through the first group of established end-to-end connection(s).

摘要： The present invention discloses methods and systems carried out at a network device for reducing network congestion by establishing an aggregated connection, wherein the aggregated connection comprise a plurality of virtual private network (VPN) tunnels. The system further comprises assigning default weights to the plurality of VPN tunnels along with transmitting and receiving data packets of a data session through the aggregated connection. When there is a missing data packet in the received data packets, the missing data packet is recreated based on a previous or a next data packet. Furthermore the present invention discloses methods and systems for determining whether a VPN tunnel from the plurality of VPN tunnels is experiencing an unacceptable packet drop rate. If it is seen that a VPN tunnel is experiencing an unacceptable packet drop rate, an effective weight of the at least one VPN tunnel is decreased in order to overcome the setback.

摘要： The present invention discloses methods and systems for processing data packets received at a first network node and for processing encapsulating packets received at a second network node. The first network node receives data packets from its network interface. It then selects a first tunnel and selects none or at least one second tunnel according to a selection policy. Original encapsulating packets (OEPs) are transmitted to a second network node through the first tunnel and at least one duplicate encapsulating packet (DEP) is transmitted through the at least one second tunnel. The second network node receives an encapsulating packet with a global sequence number (GSN) through an aggregated connection. The second network node determines whether one or more data packets corresponding to the encapsulating packet have been received earlier. The second network node may then determine whether or not to forward the one or more data packets.

摘要： 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.

摘要： A method carried out by a first communication gateway for transmitting broadcast data. Broadcast data is first received through a first network interface. The first communication gateway determines whether the broadcast data satisfies at least one condition, and forwards the broadcast data through at least one tunnel and through a second network interface to a second communication gateway if the broadcast data satisfies the at least one condition. The broadcast data is encapsulated in at least one encapsulating packet and the at least one encapsulating packet is decapsulated by the second communication gateway in order to retrieve the broadcast data. The broadcast data is then distributed by the second communication gateway to a second network.
