### Calibration (with demo) and remote configuration of WR nodes
|
|
|
|
|
|
|
|
To ensure a sub-nanosecond synchronization, the White Rabbit software
|
|
|
|
stack needs to estimate the communication link asymmetry. In this talk
|
|
|
|
we will introduce the White Rabbit link delay model to characterize
|
|
|
|
various factors that make the Master-to-Slave and Slave-to-Master link
|
|
|
|
latencies not equal. To model these asymmetries we will demonstrate the
|
|
|
|
calibration procedure that can be performed in the lab before the WR
|
|
|
|
infrastructure is deployed. We will also show how to use a Simple
|
|
|
|
Network Management Protocol (SNMP) to upload calibration parameters to
|
|
|
|
the WR nodes.
