Myricom 10 Gigabit Ethernet Network Adapters
For Financial Trading using Linux or Windows
CSPi’s Myricom® network adapters with DBL™ software enable extremely low latency financial transactions. In addition, these adapters include two unique features: hardware A/B arbitration and the ability to measure the “tick to trade” latency with single-digit, nanosecond accuracy.
Hardware A/B Arbitration
Myricom adapters can arbitrate the A and B sides of multiple feeds for both fiber and microwave sources (4-way arbitration). The adapters ship with a configuration file defining how A/B is done for many popular equity and option feeds. Users can extend this file to define feeds that aren’t available from CSPi. Offloading A/B arbitration with hardware reduces “tick to trade” latency further than competitive products can achieve. It also removes significant traffic from your servers’ shared DRAM subsystems. Turning on A/B adds zero extra latency to the adapter’s receive path.
Nanosecond Latency Measurements
Myricom 10GbE adapters can measure your application’s latency with less effort and more accuracy than any expensive, packet capture device can achieve. All packets arriving at the adapter are timestamped. Moreover, Myricom adapters are unique in that they also timestamp packets as they leave the adapter, feeding those times back into your application. The on-card TCXO oscillator is extremely accurate but even greater accuracy can be obtained by attaching a higher resolution OCXO or rubidium atomic clock time source to the coax input provided.
Myricom products have been focused on low-latency networking since 1994. Myricom DBL™ software is the industry’s original, and thus most mature, user-space TCP/UDP stack available today. Introduced in 2010, it has been in continuous operation by many financial organizations ever since. DBL offers both a socket-like API and a transparent acceleration mode (a replacement for the host’s socket library). The transparent acceleration mode allows the customer to run his existing sockets application without modification. The optional API mode is optimized for lower latency and provides access to additional features.
- 10GbE adapter that out performs the competition at “tick to trade”, particularly when you exploit our hardware offload features
- A/B arbitration in hardware for up to 4 sources per feed (fiber and microwave arbitration)
- No dropped packets even during the busiest time of the trading day
- Industry’s largest host buffers in case your application cannot keep up with surges in feed transaction rates
- Application “tick to trade” latency can be measured with single-digit nanosecond accuracy
