ETNA Project Outline The objective of ETNA is to analyze, design, and validate future metro and core networks based on Ethernet technology. The goal is to propose the architecture of a low cost pan-European Ethernet network capable of serving millions of subscribers, providing common, reliable and secure transport architecture for different current and future network services. The successful development of such networks will shape future developments of information and communication technologies and will deliver significant benefits for European citizens and business. Low cost, scalable and efficient Ethernet transport networks will enable the development of a wide range of innovative applications and will create new opportunities for high value products and services. The ETNA consortium will perform analysis and identification of the requirements for new and innovative nation-wide Ethernet networks, research and develop architectures necessary to operate these networks in a cost-effective manner, design the network capabilities to deliver services to residential, business and mobile subscribers and investigate techno-economic models of such architectures.
