PTP+Squared Clock Sync Grid System
A Grid based 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.
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.
Classic PTP: Only Single source
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.
