Reconfigurability issues in metro DWDM networks

With increasing packet-based traffic in metro networks, fast reconfigurability is becoming a requirement for optical networks. Since manual reconfiguration could take weeks, carriers are upgrading their SONET/SDH infrastructures with reconfigurable optical add-drop multiplexers (ROADMs) and tunable optical filters. This paper looks at the issue of the impact of reconfigurability on a network's performance.
