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 rust 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. When the VPN concentrator receives the first encapsulating packet, the VPN concentrator decapsulates the first data packet from the first encapsulating packet and encapsulates the first data packet in a second encapsulating packet. The VPN concentrator then transmits the second encapsulating packet to a first network device using a second aggregated VPN connection.

Claim (Index 21):
A method for transmitting and receiving data packets between a first network device and a second network device, comprising the steps of:\n (a) at the first network device, establishing a first aggregated tunnel with a third network device using a first protocol; (b) at the second network device, establishing a second tunnel with the third network device using a second protocol; (c) when the first network device transmitting first data packets to the second network device, the first data packets are first transmitted through the first aggregated tunnel from the first network device to the third network device, and then are transmitted through the second tunnel from the third network device to the second network device; (d) when the second network device transmitting second data packets to the first network device, the second data packets are first transmitted through the second tunnel from the second network device to the third network device and then are transmitted through the first aggregated tunnel from the third network device to the first network device; and wherein the first aggregated tunnel comprises a first plurality of tunnels.
