Tal,

This I-D did introduce some typical problems in the deployment of synchronization networks. We can give more deployment analysis in other documents if the WG has interest. 
With regard to scales, several cities in China already have 10,000+ mobile backhaul packet equipments, and all those equipments are required to take part in the synchronization network.

Thanks,
Yuanlong

Hi Yuanlong,

Since some of the co-authors of this draft are operators, it would be great if you could share your deployment experience with the working group (scales, statistics, accuracy, typical problems, lessons learned). This would definitely help to better understand the scalability problem statement.

Cheers,
Tal.
