METHOD AND SYSTEM FOR ALGORITHM-BASED ADDRESS-EV ADING NETWORK SNOOP AVOIDER

摘要

A method and system for an algorithm-based network snoop avoider is provided . A first data processing system and a second data processing system communicate on a physical network by transmitting data packets on the network using a virtual private network (VPN). Data packets are transmitted through a first VPN tunnel between the first data processing system with a first network address terminating a first end of the VPN tunnel and the second dat a processing system with a second network address terminating a second end of the first VPN tunnel. The VPN is automatically reconfigured to use alternate addresses on the network for the tunnel endpoints by automatically determining, in accordance with a predetermined algorithm, a third network address and a fourth network address and by automatically assigning the thir d network address to the first data processing system and the fourth network address to the secon d data processing system. Data packets may then be transmitted through a second VPN tunnel in which a first end of the second VPN tunnel is terminated by the first data processing system using the third network address and a second end of the second VPN tunnel is terminated by t he second data processing system using the fourth network address. The data packets may be transmitted using Internet Protocol (IP), and a portion of the network may include the Interne t.
