Hierarchical-Context Area Network as a Virtual Private Network Infrastructure System

A virtual private network infrastructure (VPNI) system operating a hierarchical-context area network as a VPNI network, the VPNI system comprising:

• a first virtual private network (VPN) server;
• a second VPN server;
• and
• a third VPN server, wherein the first VPN server:
• maintains a VPN tunnel between the first VPN server and an end user device;
• receives, from the end user device, via the VPN tunnel, a first protocol data unit addressed to an external device;
• identifies the second VPN server as a current point of egress for transmitting the first protocol data unit to the external device;
• receives, from the end user device, via the VPN tunnel, a second protocol data unit addressed to the external device;
• identifies the third VPN server as the current point of egress for transmitting the second protocol data unit to the external device, such that the current point of egress changes from the second VPN server to the third VPN server without reconnection of the VPN tunnel;
• receives, via the hierarchical-context area network, a return protocol data unit originating from the external device;
• and
• transmits, to the end user device, via the VPN tunnel, the return protocol data unit.

A non-transitory computer-readable storage medium, comprising processor-executable instructions for operating, in response to the instructions, a hierarchical-context area network as a virtual private network infrastructure (VPNI) network, wherein operating the hierarchical-context area network includes:

• maintaining, by a first VPN server in the hierarchical-context area network, a VPN tunnel between the first VPN server and an end user device;
• receiving, by the first VPN server, from the end user device, via the VPN tunnel, a first protocol data unit addressed to an external device;
• identifying, by the first VPN server, a second VPN server in the hierarchical-context area network as a current point of egress for transmitting the first protocol data unit to the external device;
• receiving, by the first VPN server, from the end user device, via the VPN tunnel, a second protocol data unit addressed to the external device;
• identifying, by the first VPN server, a third VPN server in the hierarchical-context area network as the current point of egress for transmitting the second protocol data unit to the external device, such that the current point of egress changes from the second VPN server to the third VPN server without reconnection of the VPN tunnel;
• receiving, by the first VPN server, via the hierarchical-context area network, a return protocol data unit originating from the external device;
• and
• transmitting, by the first VPN server, to the end user device, via the VPN tunnel, the return protocol data unit.
