Triple play convergence is now one of the important national strategies in China. Stimulated by the need of building a network that is capable of both Telecom and broadcasting services, an optical transport network (OTN) testbed is planed and deployed in Eastern China from 2009 to 2011. This testbed demonstrates the state of the art technologies in optical transport network design. It also features functions like role based network/resource management and network virtualization. In this paper, we will introduce the background of this effort and detailed design in network control, management and virtualization. We will also present our measurement experiences and results in this testbed regarding dynamic service provisioning, along with our recent efforts in standardizing performance metrics and measurement methodologies.
