1. Worked with Professor Brigitte Jaumard and Ciena Inc on research for optimizing the optical networks.2. Heuristic algorithms design and implementation, including a reactive and proactive defragmentation algorithm, i.e., push-pull, a reactive defragmentation algorithm (make-before-break), and their combination usages.3. Dynamic network provisioning and defragmentation simulation, and test algorithms in real geographical topologies, e.g. USA, Germany, and Japan, more than 200 scenarios are simulated according to different provisioning and defragmentation algorithms.keywords: Research, Algorithm Design & Optimization, Networking Optimization, Routing Spectrum Allocation, Dynamic Requests Provisioning, Defragmentation, Maven, Sqlserver.
