List of PTP implementations Systems supporting Precision Time Protocol
Screenshot of PTPd 2.3.1, an implementation of PTP for Unix-like systems Precision Time Protocol (PTP) is a widely adopted protocol for delivery of precise time over a computer network . A complete PTP system includes PTP functionality in network equipment and hosts . PTP may be implemented in hardware , software or a combination of both.
PTP is implemented in end systems and in PTP-aware networking hardware . PTP implementations may have the ability to serve as a source of time for the network, a grandmaster , or operate as a slave and receive time and synchronize to the grandmaster. Some implementations are able to operate as either master or slave.
