Problems solved by technology

[0003] However, there are many reasons for the sender to resend the data message, for example: data message loss caused by unreliability of network transmission, data message error caused by transmission link error; There are also many reasons for the data packets, such as: data packets resent by the sender, data packets generated by network replication, etc., so that the fast retransmission mechanism in the above-mentioned prior art cannot accurately know the transmission quality of the transmission network , may cause unnecessary fast retransmissions to inject excess load into the network, increase network bandwidth and performance overhead, and result in a waste of network resources

Abstract

The invention provides a data transmission method, data transmission equipment and a data transmission system. Transmitting-end equipment transmits M SCTP (stream control transmission protocol) reports to receiving-end equipment, each of the M SCTP reports carries the value of transmission times to lead the receiving-end equipment to obtain the total number M of the SCTP reports by computation according to the value of the transmission times carried in the received N SCTP reports, so that the problem of unnecessary repeated retransmission of lost data blocks due to incapability of accurately knowing transmission quality of a transmission network in the prior art can be avoided to a certain degree, and further, network bandwidth and performance expenditure are reduced, and network resources are saved.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a data transmission method, equipment and system. Background technique [0002] The Stream Control Transmission Protocol (SCTP for short) provides reliable transmission between two SCTP endpoints by establishing a coupling between the two SCTP endpoints. In order to solve the problem of data loss caused by unreliable transmission, the existing technology adopts a fast retransmission mechanism. For a data message, if a Selective Acknowledgment (SACK) response from the peer is not received, it is determined The peer end has not received the data packet and needs to resend the data packet. [0003] However, there are many reasons for the sender to resend the data message, for example: data message loss caused by unreliability of network transmission, data message error caused by transmission link error; There are also many reasons for the data packets, such as: data packets resent b...
