RESEARCH OVERVIEW

Abstract

Achieving ultra-low latency (ULL) with end-to-end delays of 1–5 milliseconds is vital for real-time applications such as high-frequency trading, autonomous vehicles, and personalized e-commerce. This study defines latency as the time from initiating a data processing task to receiving its result, proposing a holistic approach to ULL through optimized hardware, software, and network components. Latency is broken down into network, I/O, processing, queuing, application, and security factors, reducing the standard ~19 ms latency to below 5 ms with targeted enhancements. Key strategies leverage high-performance hardware (NVMe SSDs, FPGAs, GPUs), low-latency interconnects (InfiniBand with RDMA), and efficient software. A real-time fraud detection scenario handling 10,000 concurrent queries per second is analyzed, detailing tiered technology stacks. The study contrasts networking protocols, emphasizing InfiniBand’s sub-microsecond latency advantage for ULL, and demonstrates feasibility with edge infrastructure, dedicated instances, and RDMA-enabled NVMe-oF. This framework offers practical guidance and cost estimates for 2025 ULL implementations, acknowledging that actual latency, performance, and costs may vary by use case.
