Multi-layer Virtual Transport Network management

Our approach offers a generalized and structured framework to realize the full potential of SDN using recursive scoped management, and our VTN-based approach provides communication service with explicit Quality-of-Service (QoS) support for applications via transport flows. Each VTN involves all mechanisms (e.g., addressing, routing, error and flow control, resource allocation) needed to support such transport flows. Based on this approach, we design and implement a management architecture, which recurses the same VTN-based management mechanism for enterprise network management. Our experimental results show that our management architecture achieves better performance demonstrated through unicast and multicast video applications.
