... Use the optical layer to provide recovery. Our routing is well suited to packet-switched traffic, but does not rely on a specific protocol such as IP or ATM. Instead, our access scheme operates below such protocols. Recovery is performed at the optical layer, in a manner which is robust, simple and ...
