Abstract
A method includes the following steps: sorting service data into retransmissive service data and non-retransmissive service data; allocating resources to the retransmissive service data and the non-retransmissive service data respectively, and encapsulating the data into DTUs according to the allocated resources; sending, by a sender, the DTU that bears the service data; receiving, by the sender, a retransmission request that is sent according to a result of judging a bit error and a type of the retransmissive service, where the retransmission request carries information about the DTU that needs to be retransmitted; and retransmitting, by the sender, a corresponding DTU that bears the retransmissive service data requested for retransmission.
