PTP+Squared Clock Sync Grid System

Through auto discovery and configuration the Squared overlay network is a seamless addition to your standard PTP environment creating nanosecond sync and lossless distribution.

A Grid based system

Intelligent mesh creation

If every node can automatically set itself up to receive time from the best sources available and distribute time to other sources with zero intervention and the transmission is nearly lossless, then there are some cool things that follow as a result : 

  • As time is propagated from node to node the root distance is increased for every hop

  • The cumulative error of the source is used to determine the hop cost

  • Additionally static hop costs can be added

  • This approach ensures that we form a directed acyclic graph #LoopFree

PTP+Squared: Multiple independent sources

Timebeat takes a much more robust approach by allowing individual nodes in the network to compare time received from the:

  • Existing boundary clock distribution network

  • From an independent source of time

  • And from other nodes in the network.

A key challenge with the boundary clock based distribution model is that time is not delivered from a central point that can be monitored easily. Instead each and every boundary clock becomes a potential source of error.

Each point introduces the chance of error, each cable between these points introduces the possibility of error.

So long as the time feed from every boundary clock is not monitored by comparing it to several independent sources it leaves open the possibility that error in the system goes unnoticed.
