Abstract
With the Internet Protocol (IP) being the dominant protocol for new
network services, there is increasing pressure to optimize the network
infrastructure and protocols for IP traffic. We have designed a network
architecture where each node integrates a router and an optical layer cross
connect to create a router optimized for the optical Internet. IP is
responsible for all networking functions including network optimality and
packet and optical resource management, but delegates transmission work to the
optical layer,exploiting the capacity of the optical layer cross-connects.
While all control and signaling uses IP, the optical lightpaths may carry
arbitrary traffic,and so the control applies as well to non-IP
traffic.
