You can configure the BIG-IP system to manage traffic for low-latency electronic trading. The BIG-IP system optimizes Financial Information eXchange (FIX) protocol connections to achieve predictable latency and jitter, a critical aspect of successful low-latency electronic trading. When you acquire a special license, you can use the FastL4 profile to optimize the necessary connections, and use the Packet Velocity ASIC (PVA) to minimize any latency and deliver high performance L4 throughput without software acceleration.
Induced latency, which is the latency realized after a FIX connection is established, typically has a duration of approximately 10 µsecs or less.
You can configure the PVA acceleration variables on both the global db variable, pva.acceleration, and the profile setting, pva_acceleration, for low-latency electronic trading. If you set either variable to none, then any other setting is overridden. If you set either to guaranteed, then the assist or full setting is overridden. If both variables are set to assist or full, then the per-virtual setting is applied.
|DB Variable||Per-Virtual Variable||Result|
|none||Any variable.||No acceleration.|
|guaranteed||Any variable, except not-none.||Guaranteed.|
There are several tasks you can perform to implement low-latency electronic trading.
