This paper evaluates different architectures for multilayer IP transport networks. The evaluation is based on an exemplary network dimensioning of a reference IP backbone network topology, connecting 63 points of presence (PoPs) in Germany. The network dimensioning results are used for a techno-economic analysis of the different network architectures,(More)
Biomedical research on human subjects often requires a large amount of data to be collected by personal interviews, Internet based questionnaires, lab measurements or by extracting data from paper or electronic health records. This data needs to be stored, analyzed and interpreted in a comprehensive manner. There is a great need for user-friendly software(More)
Both the OIF and IETF inter-domain interfaces for control plane enabled networks are based on GMPLS protocols. OIF interfaces include ITU-T/ASON specic extensions, resulting in interoperability issues. Moreover, the connection services considered by the OIF are focused on SONET/SDH, OTN (i.e., G.709)and Ethernet, but do not consider lambda services for(More)

The paper analyzes future services in next generation optical transport networks. QoS and resilience requirements are derived for different services. Trends and evolutions in optical network architecture design are reviewed against the needs of incumbent providers. The paper proposes different network architectures for aggregation and core networks and(More)
