The project investigated scientific, technical and technological concepts and solutions for future communication networks. The research work was focused on novel architectures and solutions for a safe and secure next generation telecommunication infrastructure. Security, safety, and reliability aspects were addressed by applying innovative coding approaches to achieve safe and reliable transmission. Efficient packet coding schemes were investigated for a safe end-to-end packet transport and error correction coding schemes for higher order modulation formats to combat impairments. Safe and reliable networking based on efficient multi-layer protection, restoration and disaster recovery schemes were investigated to cope with hardware and software failures in transport infrastructure and control. Moreover, scalable, reliable and energy-efficient network and node architectures were targeted, taking benefit from low energy optical transport networking techniques. Centralized versus decentralized node architectures and related layer depended functionalities were studied. In the frame of the work towards a safe, efficient and reliable network architecture a scalable approach applying distributed network nodes with novel, basically modular hardware and software architectures was chosen. The work was focused mainly on the architecture of such network nodes and the improvement of the required components and subsystems (optical and electronic switching matrices, DWDM transport systems). Special focus was on availability and scalability. Investigation of security issues of a reliable physical transport infrastructure consisting of optical layer, transport layer and Internet Protocol layer by taking benefit of process encapsulation, virtualization, modular control and adaptive, flexible and reliable optics. Network virtualization was investigated in order to enhance network safety due to network slicing, since errors can be isolated more easily. The main focus of the work on physical layer technologies was placed on investigation of energy efficient and reliable adaptive optical systems based on software defined coherent transponder and advanced error correction coding schemes for adaptive, safe and reliable transport operated close to physical limits and adapt to the quality of the transmission links. For this work higher-order modulation formats were utilized targeting for realization of compact and reliable optical systems The close collaboration with horizontal projects targeted to accelerate and foster the technology development
