This project focuses on the design and construction of a hybrid top-of-rack switch architecture that supports fast optical switches such as Mordia. Meeting this challenge has necessitated predicting and shaping network demand, resulting in a hybrid optical/electrical ToR switch. Understanding real-world data center traffic patterns and workloads is critical to evaluating our designs. We worked with Facebook to deploy measurement and monitoring equipment throughout their network, including flow-level capture and packet-header capture.
