Napatech is a UK-based company that sells packet interception devices that allow extremely accurate packet time stamping. This is important for measuring quality of service factors, such as latency, in packet networks.
Napatech network adapters can be synchronized with a variety of time sources, such as Global Positioning System (GPS), IEEE 1588v2, CDMA and Pulse Per Second (PPS) sources. This allows packets to be time-stamped with an accuracy of 50 nanoseconds. The time synchronization solution also allows Napatech adapters to be daisy-chained allowing a single time synchronization source for multiple adapters.
Napatech intelligent adapters can be used for performance monitoring, test & measurement, security and optimization markets. The boards provide interception from 1 Gbps to 10 Gbps. Software is available for Linux, FreeBSD and Windows.
