Metropolitan optical network

The project develops an optical wavelength division multiplexing (WDM)-based transport layer to support an asynchronous transmission mode/synchronous digital hierarchy (ATM/SDH) network in providing, in a cost-effective manner, a significant number of subscribers with a multi-service network. Network requirements and dimensioning are identified by analysing a future multi-service metropolitan network. A demonstration is being staged in the Stockholm Gigabit Network that will display various services/applications over an ATM switched network. An optical layer will be developed together with a management system to serve as a reconfigurable infrastructure for ATM/SDH networks. Critical optical components for such a WDM network will also be developed. So far the following results are available: a strategy in exploiting WDM networking within a metropolitan network; a demonstration showing interoperation of an optical WDM transport layer, an ATM switched network layer, and a multi-service layer; a management system that demonstrates operation of a WDM network layer; guidelines for management system architecture, information models and design strategies; pushing the technology to enable a cost effective and robust implementation of optical network elements; contribution to the standardization activity on optical networks; development of a cost/dimensioning tool, DIAMOND (Dimensioning Application for Multi-wavelength Optical Network Design), for evaluation of different WDM network designs; operation of the first optical add/drop multiplexer (OADM) node with CORBA management interface within SGN; generation of a benchmark table that compares characteristics of different component technologies.
