The Design And Implementation Of Optical Switching Platform Architecture And Management Mechanism

With the rapid development of Internet digital services, cloud computing, network traffic shows an exponential increase. All these have led to high energy consumption. Under the guidance of low carbon and energy saving concepts, developing new large capacity, low energy consumption network switching equipments become more and more imperative. Compared to electrical switching fabric, optical switching structure has become a shinning star in industry because of its obvious advantages in bandwidth and energy consumption.Currently network equipments widely exist huge power consumption and high waste problems. The reason is that all those switching equipments are lack of energy efficient management. Scientific energy-based management mechanism not only offers a good guarantee on performance and reliability, but also ensures energy efficient. It’s a significant research topic and may be the trend of future.The work in this thesis is part of national “12th Five-Year Plan” special project / national high-tech program “Novel High Capacity All-optical Switching Network Structure and Key Techniques, Protocols and Performance Evaluation Method”. The author does some research, design and implementation work on the optical switching node architecture and platform management system below energy saving target in the project. The thesis’ s main contributions include:1. Make a comprehensive analysis of switching fabric on optical & electrical technology, energy consumption, etc. Choose the “electrical card + optical backplane" as the final form of our switching structure. And then design some key modules of the large capacity, low energy consumption optical switching structure.2. Implement electrical / optical structure in Advanced Telecom Computing Architecture, which comprises verification of backplane transmission with high speed data, specific implementation form of modular structure and design of dividing the structure into data plane, control plane and management plane.3. Design the switch node architecture management mechanism with the Advanced Telecom Computing Architecture management mechanism and related research.4. Complete implementation of the platform management controller’s hardware and software system. Apply the designed management mechanism into management controller system. And finally test some correlation functions of the platform management controller.
