"Why should we go through all of the intermediate mappings?" asks Paul Zalloua, director of product marketing for LuxN, a maker of optical access platforms designed to extend optical services from the MAN point of presence to enterprise customer premises at 2.5G bit/sec. "Our goal is to map everything in light. Why not take T-1 into optics?"
Zalloua says another issue to be worked out in the convergence of IP and optics is network monitoring. Some of the same constructs used to monitor traffic in the packet world will not be suitable in the wavelength world, he says. "Counting packets dropped and received is not going to scale up," he says.
