Abstract
A virtual private network (VPN) gateway selects a VPN connection, from multiple VPN connections established between a network VPN gateway and a remote VPN gateway, based on performance factors such as throughput. A system may measure throughput in megabytes per second (Mbps). More specifically, a VPN gateway (e.g., a remote VPN gateway or a network VPN gateway) can configure a routing preference that selects a VPN connection that is more performant based on a cryptographic algorithm that is used for the VPN connection. The VPN gateway can update the routing preference to select an alternative VPN connection when the performance of the VPN connection suffers.
