Abstract

Methods and systems consistent with the present invention establish a virtual network on top of current IP network naming schemes. The virtual network uses a separate layer to create a modification to the IP packet format that is used to separate network behavior from addressing. As a result of the modification to the packet format, any type of delivery method may be assigned to any address or group of addresses. The virtual network also maintains secure communications between nodes, while providing the flexibility of assigning delivery methods independent of the delivery addresses.
