IEEE 1588 Precision Time Protocol

Synchronized networked measurement and execution across target computers with PTP

The Precision Time Protocol (IEEE® 1588-2008) synchronizes clocks throughout a computer network. For more information about the standard, see standards.ieee.org .

To interface to a PTP network, use the PTP protocol blocks. The blocks connect to Intel® Ethernet boards that implement the PTP clock and that are compatible with PCI-standard bus architectures, such as PCI, PCI Express®, and PXI®. For detailed information about PTP-compatible boards, see the manufacturer documentation.
