Attend this technical seminar exploring innovative optical networking solutions for next-generation datacenter infrastructure. Learn about the challenges facing traditional CMOS-based electrical packet-switch ASICs in the post-Moore's law era and discover how optical circuit-switching (OCS) technologies offer sustainable alternatives with data rate agnosticism, negligible power consumption, and minimal forwarding latency. Explore the novel OSSV architecture that combines OCS-based core connectivity between Top-of-Rack switches with reconfigurable OCS-based edge connections between servers and ToR switches. Understand the Skewness and Volume (SV) minimization optimization framework designed to balance traffic skewness reduction and inter-rack traffic volume minimization. Examine simulation results and testbed evaluations demonstrating how OSSV significantly reduces performance gaps between all-optical DCN cores and non-blocking packet-switched DCNs across diverse traffic scenarios while maintaining low power consumption and cost. Gain insights into the practical implementation challenges and solutions for deploying optical circuit-switching in modern cloud infrastructures supporting HPC, distributed machine learning, and deep neural network applications with stringent performance requirements.
