Abstract:
A method for communicating on a wide area network between a first data processing system and a second data processing system, the method comprising the computer-implemented steps of:establishing a virtual private network (VPN) tunnel using a first network address for the first data processing system and a second network address for the second data processing system, wherein the first network address and the second network address are addresses used to route data over the wide area network; transmitting data packets on the wide area network from the first data processing system to the second data processing system using the VPN tunnel; and automatically selecting, during a same session between the first data processing system and the second data processing system, an alternate VPN tunnel for transmitting data packets on the wide area network from the first data processing system to the second data processing system by selecting alternate network addresses for the first data processing system and the second data processing system, wherein the alternate network addresses are addresses used to route data over the wide area network, and wherein the alternate network addresses are different from the first network address and the second network address.
