Measure and improve clock synchronization using combination of transparent and boundary clocks

A method comprising:

• measuring, based on a first communication session between a boundary node and a slave node in a communication network, a first timing delay from the boundary node to the slave node;
• measuring, based on a second communication session between a working master node and the slave node, a second timing delay from the working master node to the slave node;
• determining a timing delay correction factor based on the first timing delay and the second timing delay, wherein the timing delay correction factor is based on a difference between the first timing delay and the second timing delay, and
• synchronizing the slave node with the working master node based on the timing delay correction factor.

A non-transitory computer-readable medium having stored thereon instructions which, when executed by one or more processors, cause the one or more processors to:

• measure, based on a first communication session between a boundary node and a slave node in a communication network, a first timing delay from the boundary node to the slave node;
• measure, based on a second communication session between a working master node and the slave node, a second timing delay from the working master node to the slave node,
• determine a timing delay correction factor based on the first timing delay and the second timing delay, wherein the timing delay correction factor is based on a difference between the first timing delay and the second timing delay, and
• synchronize the slave node with the working master node based on the timing delay correction factor.
