Abstract:The FEDERICA project is to create a virtual network environment that is dedicated to investigate and trial novel network protocols and services, as well as Future Internet architectural concepts and emerging applications. With this purpose in mind, a technology agnostic network infrastructure that consists of transmission devices, gigabit connections, and computing resources has been created. The physical FEDERICA network footprint is mapped to the existing GÉANT network links and additional NREN connections and creates its own infrastructure on top that allows resource virtualisation. The project partners do research on novel resource virtualisation techniques as well as share their operational experiences on virtualisation capable infrastructures during the project lifetime. Within the framework of FEDERICA, close cooperation has been established with various standardization bodies such as IETF, ITU-T, OIF, and IPsphere. Although, the main objective of the project is to create a physical environment that allows obtaining dedicated virtual slices of the infrastructure configured by the users, the project also facilitates information exchange, initiates technical discussions among the experts and disseminates scientific results primarily to national research and education network community. The
SDN/OpenFlow solutions have shown their strengths in datacenter, cloud and experimental environments. Currently there is a number of activities employing SDN concepts to other use cases. The ADDONAS project (Active Distributed & Dynamic Optical NetworkAccess Systems) proposed to use SDN concept to support access to the services for the users and fair access to the resources for service providers. This paper presents the work done in the ADDONAS project, discusses architecture and describes development related to deployment of the SDN system to enable flexible service provisioning in combined metro and access architectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
