![]() Then, PTP measures the exact message transmit and receive times and uses these times to calculate the communication path delay. PTP sends messages between the server and client device to determine the delay measurement. To ensure clock synchronization, PTP requires an accurate measurement of the communication path delay between the time source ![]() PTP enables network routers to function as PTP devices, including boundary clocks (BCs)įor more information about PTP clock devices and their role in a PTP network, see the PTP Clocks section. Result in asymmetrical packet delay times.Īdding PTP to a network can compensate for these latency and delay problems by correctly adjusting device clocks so that they This process causes variations in packet forwarding time latency, and these variations can This delay can cause device clocks on the network to lose synchronization with one another.Īdditional delays can occur when packets entering a router are stored in its local memory while the router searches the address When the buffer is full, the router delays The router buffers some packets so that they are not lost before they are sent. When the router attempts to send multiple packets simultaneously, Routers send data packets to packetĭestinations using IP address information contained in the packets. In an IP network, routers provide a full-duplex communication path between network devices. Limited bandwidth requirement for PTP data packets Low cost and easy setup in existing Ethernet networks The benefits of using PTP in an Ethernet network include: In addition to providing time accuracy and synchronization, the PTP message-based protocol can be implemented on packet-based Timing precision improves network monitoring accuracy and troubleshooting Require extremely precise time accuracy and stability. Smart grid power automation applications, such as peak-hour billing, virtual power generators, and outage monitoring and management,
