How to synchronize a packet network

Synchronous Ethernet

IEEE 1588v2

Efficient transport of

synch over IP


Synchronization Solutions

Base synchronization will dependent on the engineering network solution.

Synchronization can be derived from：

① GPS / BITS (Building Integrated Timing Supply)

② E1/T1 lines if E1/T1 interface is used (A traditional sync. sub-network exists in IP network.)

③ Frequency Synchronization: Synchronous Ethernet, TOP, ACR…

④ Frequency & Phase Synchronization: IEEE 1588-2008, NTPv4

All these techniques are supported in Huawei RTN9xx


1588v2, GPS-Grade Clock for Mobile Networks

• Migrating from 2G/3G to LTE, Phase Synchronization becomes necessary

• IEEE1588v2 is the lowest cost solution for mobile networks to achieve Frequency

IEEE 1588-2008 – Master/Slave

1. At time t1, the master clock sends the SYN

message that carriers the t1 information. The

master clock directly inserts the value of time

t1 into the SYN message through the MAC

layer to notify the slave clock

2. At time t2, the slave clock receives the SYN

message

3. At time t3, the slave clock sends the REQ

message

4. At time t5, the master clock sends the RESP

message that carriers the t4 information

Offset and Delay exist on a network:

Offset: difference between the time of the

master clock and the time of the slave clock

Delay: Caused by network transmission

t2 – t1 = Delay – Offset

t4 – t3 = Delay + Offset
