DAVID IST project

David Data and voice integration over DWDM

July 2000 – October 2003
IST-1999-11742

Main objective is to propose a Packet-over-WDM network solution, including traffic properties and management, based on optical packets and asynchronous transmission over metro and backbone distances. The project will capitalise on both optics and electronics to find out the optimum combination to reach multi-Tb/s capacity. To cope with the on-going convergence in the transport of voice, data and multimedia applications, the project will also define several classes of service, adapted to optical layer specifics. On the metro side, the project will consider a buffer-less network using a medium access control protocol. The backbone will be based on 10 Tb/s multi-layer (wavelength and packet) opto-electronic medium access control protocol with opto-electronic packet routers, incorporating core and edge functions. Finally, the project will demonstrate highly integrated optical and electronic devices, included in a sub-equipped experimental platform.
