METHODS AND SYSTEMS FOR REDUCING NETWORK CONGESTION

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.

1. A method carried out at a network device for reducing network congestion comprising the steps of:
(a) establishing an aggregated connection, wherein the aggregated connection comprising a plurality of virtual private network (VPN) tunnels; (b) assigning default weights to the plurality of VPN tunnels; (c) transmitting and receiving data packets of a data session through the aggregated connection; (d) when there is at least one missing data packets in the received data packets: recreating the at least one missing data packets based on at least one previous or at least one next data packet; (e) determining whether at least one VPN tunnel of the plurality of VPN tunnels is experiencing an unacceptable packet drop rate; (f) if the at least one VPN tunnel is experiencing an unacceptable packet drop rate: decreasing an effective weight of the at least one VPN tunnel.
