Abstract
Systems and methods for communication. A network abstraction layer (NAL) is built on a public Internet, the NAL comprising an overlay network allowing a direct Internet Protocol (IP) communication between endpoints in a virtual private network (VPN) over the Internet. A network virtualization layer (NVL) is built on the NAL, the NVL comprising a VPN aggregator using DGOI protocol encryption, providing synchronization of session keys to encrypt a payload between all the endpoints over the NAL such that encrypted traffic is able to be decrypted by any endpoint for an entire session to allow instantly available communication between all the endpoints.
