Ultra-Low Latency Network and Physical Infrastructure Design
Achieved end-to-end tick-to-trade latency in the range of 100–500 nanoseconds through co-designed network and physical infrastructure.
Situation
Even with optimized compute, network and physical transmission layers remained a dominant source of latency. Standard networking equipment and fiber introduced avoidable delays.
Solution
A custom low-latency infrastructure stack was designed. The network was treated as an extension of the compute pipeline, not a separate layer.
