Will RC continue to transfer the data if the link failed or it will start from beginning?

Dear expert, 

we are using two 3PAR and RCIP to protect our data.

Because the link quality sometimes is bad, latency average 200~300ms, I want to know if 3PAR will continue to transfer data or it will start from the beginning?

The offset and length of the I/O that failed to complete on the secondary virtual volumes because the link failures are recorded in the nonvolatile memory.

The system records failed I/O replication separately because remote copy creates the snapshots of the primary virtual volumes on the primary system after I/O is written to the primary virtual volumes, but before remote copy can write the I/O to the secondary virtual volumes. These recorded failed I/O operations are complete when the replication links return and before resynchronization of the volumes occurs.
