You canĮnable the client mode on up to two interfaces Synchronize its clock to the server clock.Ĭlient mode-Synchronizes its clock to a server clock. To one or more client clocks, thus allowing the client to Server mode-Distributes timing information over the network All clocks are synchronized to the grandmaster clock.Īn ordinary clock is a 1588 clock with a single PTP port that can operate in one of the following modes: PTP is designed specifically for industrial, networked measurement and control systems, and is optimalįor use in distributed systems because it requires minimal bandwidth and little processing overhead.Ī network device physically attached to the primary time source. Systems, and was developed to synchronize the clocks in packet-based networks that include distributed device clocks of varying Precision Time Protocol (PTP) is defined in IEEE 1588 as Precision Clock Synchronization for Networked Measurements and Control Messages ensure continued synchronization. On the network synchronize their clocks with the server clock and are referred to as members. This clock is referred to as the server clock. Is connected to a device with the most precise clock. The clocks in are organized into a server-client hierarchy. However, you can monitor their usage indirectly by monitoring the Internet router they are connected to and you can monitor other devices in order to build up an overall picture of usage on your network.The Precision Time Protocol (PTP), as defined in the IEEE 1588 standard, synchronizes withnanosecond accuracy the real-timeĬlocks of the devices in a network. "Passive" devices that don't support running SNMP or UPnP can't generally be monitored as there is no way to query them. Monitoring the throughput of my iPhone / iPad / Android phone / PlayStation / Xbox etc. How can I enable them? for more information. These types of devices are relatively easy to monitor as they either support SNMP or can have SNMP enabled.Ĭheck out our guide: I'd like to monitor my Mac/PC/Linux devices. Monitoring the throughput of my Mac / PC / Linux workstation / server If you're unsure, try generating some traffic of a known speed ( is excellent for this) and comparing it to what you see in PeakHour. Most routers support monitoring of the WAN or Internet interface and may also support monitoring of the WiFi interface (if supported) and ethernet ports (either as a group or individual).Īll routers however are different so it's not possible to provide a simple guide on which interface to use. This allows you more control and provides better visibility of what is going on on your router. SNMP is a more capable monitoring protocol than UPnP as it allows you to specify which interface's throughput you'd like to monitor. How can I check? My Router supports SNMP - what can I monitor? If you suspect the throughput PeakHour displays is not accurate, check this article for further troubleshooting tips: PeakHour isn't seeing my router / isn't reporting bandwidth / appears to be reporting incorrectly. Some router manufacturers have been known to not accurately report throughput, so it makes sense to double-check. In such cases, even if UPnP is enabled, it may not show up in PeakHour.īe sure to perform a 'sanity check' of what PeakHour is reporting vs. Note that not all routers properly implement the UPnP specification. If your router is not displayed, try resetting it. Look for your router in the detected devices list.
