Napatech, a network analysis provider, will soon offer on-board IEEE1588 PTP (Precision Time Protocol) support on Napatech 1 Gbps and 10 Gbps intelligent network adapters. Napatech customers can synchronize appliances using Napatech intelligent network adapters to an IEEE1588 PTP master or to use Napatech network as an IEEE1588 PTP master for other systems.
The IEEE1588v2 PTP time synchronization protocol is based on a hierarchical master-slave configuration allowing multiple devices to synchronize clocks over a distributed packet-based network. Synchronization messages exchanged between the PTP master and slave include nanosecond time-stamps that allow the PTP slaves to adjust their clock frequencies to compensate for delay in the network and thereby provide an accurate time of day clock reference.
Existing Napatech intelligent network adapters use time synchronization to support nanosecond precision time-stamping of captured packets, which enables precise merging of data from multiple ports and adapters in the same appliance as well as supporting accurate network monitoring analysis and troubleshooting as well as precise latency measurement.
The new on-board IEEE1588v2 PTP products are planned for release in Q4 2012. For more information, visit Napatech.
