How does PrEstoCloud support ad-hoc overlay network?
Inter-site Network Virtualization offered by PrEstoCloud allows the computing application to employ a Virtual Private Network (VPN) across a specific set of components deployed on different network infrastructures. While deploying the application, the Inter-site Network Virtualization assigns the Internal OpenVPN IP addresses used by all servers in each distinct cloud, and hence it configures the inter-cloud networks in each site. Moreover, in the context of the PrEstoCloud project, there are situations where an ad-hoc overlay network may be used in order to allow the edge nodes to communicate directly with each other and exchange data. Therefore, the requirements for overlay networks such as high-level routing and forwarding or on-demand network configuration tasks should be addressed by edge devices.
