Abstract
The techniques described herein enable the establishment of two simultaneous virtual private network (VPN) connections for a VPN client operating on a remote computing device. The VPN client can establish first VPN connection with a first VPN server instance of a VPN gateway and a second VPN connection with a second VPN server instance of the VPN gateway. To establish two simultaneous VPN connections, the VPN client is configured to create and/or use two Transmission Control Protocol (TCP) sockets. In one example, a first VPN connection can be a primary VPN connection and a second VPN connection can be a dormant VPN connection configured as a backup in case of a service interruption with the first VPN connection. In another example, a data flow can be split across the first and second VPN connections, or alternate between using the first and second VPN connections, based on performance parameters.
