We have been developing a network visualization technique: a network architecture technology to overlay IP networks over an optical backbone network to improve flexibility and resiliency. Virtual network topology created in the optical backbone network is used as a substrate for a IP network. In order to improve flexibility and resiliency, we need to implement carrier-grade mechanisms for operation, administration, and maintenance. For the IP network, the following management and controls are addressed: traffic measurement, route trace, topology and route optimization, and failure analysis. For the optical backbone network, the impact of the GMPLS control plane is addressed. We also discuss the integrated operation and management of the IP and optical backbone networks.
