Hi all,

Since the deployment of 4G mobile networks, many mobile backhaul networks are providing SyncE and/or IEEE 1588 synchronization capabilities for the cells.
As these backhaul networks consist of thousands of nodes, the scalability of synchronization networks poses as a great challenge to service providers.

This I-D provides a problem statement for scalability in synchronization networks:
https://tools.ietf.org/html/draft-hjxl-ssn-ps-00

Opinions and discussions are cordially welcome, and anyone who has interest may also drop me a private email.

Best regards,
Yuanlong
