Data transmission method, transmission node, receiving node and data transmission system

Abstract

The invention discloses a data transmission acceleration method and related device and system. The method includes that the transmission node transmits data packets to the receiving node at a specific rate, wherein each data packet carries a random serial number and a rolling serial number related to the packet transmission sequence; the receiving node receives the two serial numbers of the data packets, determines lost data packets quickly and feeds serial number information of the lost packets back to the transmission node so as to indicate the transmission node to retransmit the lost data packets. By adopting the scheme provided by the invention, network throughput rate/transmission rate can be improved in a network with high delay and high packet loss probability and acute change of the high throughput rate/transmission rate due to network jitter is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for accelerating data transmission and a related device and system. Background technique [0002] In network communication, how to ensure reliable and efficient data transmission on the network has always been the focus of research in academia and industry, and the efficiency of data transmission is directly related to the performance of network protocols. Among them, throughput / transmission rate is used to It is one of the important indicators to measure the performance of network protocols. In an existing communication network, TCP (Transmission Control Protocol, Transmission Control Protocol) or UDP (User Datagram Protocol, User Datagram Protocol) is usually used as a transport layer protocol. TCP and UDP are the two most common transport layer protocols in the TCP / IP model. According to statistics, at present, more than 90% of global Internet data tr...

Problems solved by technology

According to statistics, at present, more than 90% of global Internet data traffic is transmitted through TCP, and less than 10% is transmitted through UDP.

However, the Learning-based TCP acceleration technology needs to rely on the study of historical records to understand the current network situation, but for networks with random packet loss and large delay jitter, this learning/judgment effect is not obvious, making the network throughput rate /The increase in transfer rate is not significant

[0007] To sum up, the throughput/transmission rate of the existing transmission protocols still has a lot of roo
