Recently network virtualization has been pushed forward by its proponents as a long-term solution to the gradual ossification problem faced by the existing Internet and proposed to be an integral part of the next-generation networking paradigm. By allowing multiple heterogeneous network architectures to cohabit on a shared physical substrate, network virtualization provides flexibility, promotes diversity,...
This paper deals with principles, architecture and solution to problems of virtual automation networks for purposes of automation. Virtual automation networks represent recent trend of communication in heterogeneous networks in industrial automation. Heterogeneous networks consist of industrial automation systems such as fieldbuses, office LANs, and public networks (Internet and telecommunication...
Many researchers have considered security policy management, including how to configure policies manually and even how to automatically generate security policies based on security requirements. Both can be error prone, especially when properties of the network topology change, because security requirements are usually not bound to any particular route path. Our DETER lab emulation results show that...
