Overlay Network

Simply put, an overlay network is a network layered on top of another network. For example, the Internet was originally built as an overlay upon the telephone network. Yet today, the telephone network is increasingly turning into an overlay network built on top of the Internet with the Voice Over Internet Protocol (VoIP).

Overlay networks provide the opportunity to build additional layers of security and connectivity for your network. Nodes of overlay network are connected by virtual links that are configured to traverse the underlying physical links.

VNS3 utilizes overlay networks to add full encryption, greater visibility and control of your cloud networks which are owned by a third party. As an aside, subscribes to a version of the computing future where the veil is lifted and users have secure and attestable control of their networks without the worry of third party telemetry gathering or third party services.
