Smart routers - Simple optics: An architecture for the optical internet

With the Internet Protocol (IP) being the dominant protocol for new network services, there is increasing pressure to optimize the network infrastruct ure and protocols for IP traffic, We have designed a network architecture w here each node integrates a router and an optical layer cross connect to cr eate a router optimized for the optical Internet. IP is responsible for all networking functions including network optimality and packet and optical r esource management, but delegates transmission work to the optical layer ex ploiting the capacity of the optical layer cross-connects, While all contro l and signaling uses IP, the optical lightpaths may carry arbitrary traffic , and so the control applies as well to non-IP traffic.
