# List of PTP implementations

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.
