Problems solved by technology

[0004] Due to the poor network condition of the wireless link and the high packet loss rate, a large number of data packets need to be retransmitted when using the traditional TCP protocol. Sometimes some data packets have been received by the sink, but the ACK transmitted from the sink to the source (confirmation character) transmission failed, the source needs to retransmit the same data packet, wasting bandwidth

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0055]The transmission and feedback mechanism of the transport layer is modified, and the network coding operation is embedded in the transport layer. The specific changes are as follows:

[0056] Add a network encoding window at the transport layer ( figure 1 ), that is, the transport layer maintains two windows: the TCP window and the network coding window. The data is generated by the application layer and passed to the TCP window from top to bottom, and the network coding window accepts the TCP window data packet and caches it in the cache area. When the network coding window receives several (this number should be determined according to the specific network environment) data packets, it will generate a specified number (this number should be determined according to the specific network environment) encoded data packets, and pass them to the network layer until...

Abstract

The invention provides an improved method for a transmission control protocol based on network coding. The method comprises the steps of modifying a feedback system of the TCP protocol in a transmission layer and adding a network coding window, wherein the transmission layer maintains two windows which are a TCP window and a network coding window. The data are generated by an application layer and delivered to the TCP window from top to bottom; and the network coding window receives the data packet of the TCP window and caches the data packet to a cache region. When the network coding window receives a plurality of data packets, a designated number of coding data packets are obtained and are then delivered to a network layer and finally sent by a bottom layer. The retransmission time of the data packets can be obviously shortened, so that the network throughput is improved.

Description

technical field [0001] The present invention relates to an improved method of transmission control protocol. Background technique [0002] Network Coding (Network Coding) is a cutting-edge technology in the field of network communication. Once the theory of Network Coding was proposed, it has attracted widespread attention from academia and industry. Network coding is an information exchange technology that combines coding and routing. Based on the traditional store-and-forward routing method, the receiving node encodes multiple received data packets to increase the amount of information transmitted in a single transmission, thereby improving the overall performance of the network. Network coding can be widely used in Ad Hoc networks (self-organizing networks), sensor networks, P2P (end-to-end) content distribution, distributed file storage, and network security. [0003] TCP (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport lay...
