In this paper, we demonstrate the integration of a SiP switching platform to improve real-world Distributed Denial of Service (DDoS) defense systems. We demonstrate how DDoS mitigation in the optical domain can be transparent to network and application layers, allowing for reconfiguration and tuning. Additionally, we show how optical domain DoS mitigation provides significant cost reduction-with a 1/3 cost reduction-compared to traditional mitigation using electronic counterparts. Our approach is ideal for data-center deployments, and our testbed topology mirrors a standard data center set up.
This paper presents the integration of multiple silicon photonic (SiP) switches within a high-performance computing environment to enable network reconfigurability in order to achieve optimized bandwidth utilization. We demonstrate a physical testbed implementation that incorporates two fabricated SiP switches capable of switching traffic under real HPC benchmark workloads. The system uses dynamic optical bandwidth steering to match its physical network topology to the traffic characteristics of the application, and achieves up to approximately 40% reduction in application execution time of the high-performance computing benchmark. We present the detailed design of the network architecture and control plane of the system, and discuss the system performance improvements that arises from bandwidth-steering with silicon photonic-based circuit switching.
