Objective
Expected Achievements
To define a managed single-layer transport platform based on the "switchless" optical network concept with characteristics of flexibility, upgradeabilty and economic viability for high capacity end-to-end networking. To develop and demonstrate key advanced components for wavelength-agile HD-WDM operation in "switchless" optical networks.
To demonstrate the main features of a "switchless" optical network in laboratory demonstrators including ATM traffic transmission tests and to prove the feasibility of the key aspects for network dimensioning on a national scale.
Expected Impact
The SONATA all-optical distributed switching network will allow network operators to realise a single-layer, "switchless" network as an alternative to today's multi-layer paradigm based on relatively large numbers of high-throughput switches and cross-connects. The "switchless" alternative would eliminate the need, within the transport network, for any ATM cross-connects, SDH or optical cross-connect nodes, as well as telephone network switches. As the SONATA network approach shows a strong potential for the distribution and transport of high volume traffic by providing flexible broadband access, the project results will be able to give a valid contribution to current research activities on new network techniques and infrastructures for transport and distribution of new broadband services to the customer, and will become a key factor in the strategies of network operators for the deployment of such network platforms.
