doFSR - Optical high-speed packet switched networking

Exponentially Increasing Internet protocol (P) traffic and new quality of service sensitive applications require cost efficient solutions throughout the network. WDM technology has provided solutions for transport networks at the backbone level, and similar solutions are emerging for metropolitan area networks (MAN). One Important issue is how the network is controlled and how its resources are shared. A network system that is scalable from local switching networks to wide area networks (WAN) has been developed at VTT Information Technology, based on their proven frame synchronized ring (IFSR) concept. It does not depend on a particular transport network, but it is adaptable from parallel optical links to dense WDM systems.
