Low Latency Network Protocols

Architecture

Low latency network protocols within financial systems necessitate a highly optimized architectural design, prioritizing proximity to exchanges and liquidity providers to minimize round-trip times. This often involves colocation services and direct market access (DMA) to bypass intermediary network hops, directly impacting execution speeds. Network topologies are engineered for redundancy and failover capabilities, ensuring continuous operation even during disruptions, a critical feature for high-frequency trading strategies. Furthermore, specialized hardware, such as Field Programmable Gate Arrays (FPGAs) and network interface cards (NICs) with kernel bypass, are integrated to accelerate packet processing and reduce latency introduced by the operating system.
