RESUMO

A new system for the generation, switching and routing of optical packets is described, aimed for use in nodes of next-generation optical networks (NGON). The optical packets are composed of an in-band frequency tone header, and a high-capacity transparent digital payload (~Gb/s), occupying separate fields. The optical node switching action includes blocking, routing and drop functions, controlled by electronic logic circuits, performed on a packet-by-packet basis, with only the header information being processed. Total header processing and optical packet switching time is few micro seconds (~ms). This system is designed as a techno-economical solution for metro-access transport, having low latency and low packet loss, being fully compatible with WDM optical networks
