In the last decade, techniques of Software-Defined Networking (SDN) have grown up and brought about a new situation to computer network. It allows greater flexibility and adjustment in building network, bringing more benefits to information and network service-oriented systems. Nevertheless, the concept of Software-Defined eXchanges (SDX) also started taking shape recently. The principle of SDX aims to provide better adaptation, reliability, and performance by defining detail policies regarding to where, when, and how to process the data in advance. For network architecture, SDX may provide possibility that makes legacy network devices to achieve innovative operation scenarios with SDN designs. It is an applicable option to build an integrated, coexisted network system with both SDN and legacy infrastructure, especially for Hybrid SDN scenario. This research focuses on the study of SDX-based Internet eXchange Point (IXP), investigating the issues in network management and security. In addition, the research also tries using SDX concepts to design and develop multi-domain exchange mechanism in large-scale network. The expected approach includes the secure protection for routing exchanges in control plane, the mechanisms for proofing advertised route can be trusted, and monitoring and management capabilities in SDX scenario. The corresponding practice is planned to deploy on an emulated environment conducted by mesh VPLS/VPN nodes in TWAREN 100G backbone, and stitch it with other NREN testbeds for processing proof-of-concept evaluation collaboratively.
