A novel automated SDN architecture and orchestration framework for resilient large-scale networks

Software-Defined Networking (SDN) is a new technology paradigm that decouples the data and control planes and allows operators to manage networks via an abstraction model. SDN offers dynamism, scalability and flexibility for modern networking environments. However operators still have to design SDN solutions to deploy flow rules in an efficient and automated manner. Hence effective path computation, definition and deployment are some of the key challenges facing SDN operation. Along these lines, this work introduces a novel SDN management and orchestration framework that implements a resilient Next-Generation Path Computation Element (NG-PCE) to compute and deploy resilient protection paths. A testbed setup is also built and three simple testcase scenarios evaluated to verify overall system performance and accuracy.
