摘要

In the field of data sync technology, compared with other protocols, because of high efficiency and speed UDP transmission has been widely applied, but it can't provide a reliable data transmission service which is connection-oriented, as a result of which decreases the utilization of data transmission. Based on this, combined bulk retransmission and acknowledgement mechanism, this paper presents a new protocol UDS (Period ACK Reliable UDP) to improve the traditional UDP, merged resend task into the time slice of single circle sending to achieve virtual parallel processing for sending task and resend task. The experimental results indicate that the UDS keep the advantages of traditional UDP transmission, at same time, improve the reliability and reduce the influence of retransmission on transmission efficiency and network bandwidth.
