IPC: H04L1/18
Filed: 2020-07-16
Abstract: The present disclosure relates to a retransmission request method, which comprises: determining whether an error is present in data received from a sending end; and in response to an error being present in the data, sending to the sending end a request to retransmit data. According to an embodiment of the present disclosure, a network device can determine whether an error is present in data sent by a sending end, and when an error is present in the data, the network device can send a request to retransmit data to the sending end of the data, and thereby cause the sending end to retransmit data. Accordingly, it is not necessary for a receiving end of the data to determine whether an error is present in the data, and therefore it is not necessary for the receiving end to send a request to retransmit data to the sending end via a network device when there is an error present in the data; instead, the network device can directly send a request to retransmit data to the sending end, and when there is an error present in the data, it can be ensured that a sending terminal receives the request to retransmit data as quickly as possible, and thereby sends data to be retransmitted to the receiving end as quickly as possible.
