Multicast and the Markets with Brian Nigito

Over the past two decades, securities exchanges have transitioned from physical floors to highly regulated, electronic ecosystems where ultra-low latency determines competitive advantage. To achieve this, firms utilize specialized networking architectures like UDP multicast and co-located hardware to distribute market data faster than standard internet protocols allow, while relying on custom recovery layers and sequencer models to ensure transactional reliability. As hardware speeds approach 25 Gbps, the industry is increasingly shifting from general-purpose servers to specialized FPGAs and custom network cards to manage serialization delays and maintain deterministic performance.
