Goal
The OVNET is a joint effort among academics, research laboratories, major companies (e.g., Microsoft, Facebook, and Verisign) and operators (e.g., Level3) to provide a worldwide experimental facility. The experimental network has around 200 nodes in 27 countries and has its own IP address space (one /16 IPv4 and one /32 IPv6 prefix). The network uses Open Overlay Router (http://openoverlayrouter.org) technology which is controlled by a NIB and it is integrated with OpenDayLight. Such overlay technologies are key drivers of Over-the-Top overlay services.
