Latency Measurement

Latency measurement and monitoring

For time sensitive network applications, such as financial networks, low latency is critical. Measuring and monitoring latency is therefore essential.

Napatech adapters deliver precise time-stamping and resolution to detect sources of delay. For example for financial institutions latency can make the difference between winning and losing a trade.

Key features for latency monitoring

• Capture 100% of traffic
• Nanoseconds time stamp precision
• External time synchronization

100 % packet capture

Probes with Napatech network adapters capture 100% of network traffic, allowing anomalies that delay or disrupt transactions to be detected.

1 million times higher precision than software time stamping

Napatech network adapters provide hardware time-stamps with nanoseconds precision, long term stability allowing otherwise undetected latency differences to become visible.

Time synchronization

Accurate latency measurements require that time stamp measurements are based on the same reference clock. Napatech network adapters can be synchronized to the host OS time, to other Napatech network adapters or to external time sources:

• IEEE 1588/PTP
• CDMA
• GPS receivers including leading commercial time servers
