Accelerating method for asymmetric and multi-concurrency network

Abstract

The present invention discloses an acceleration method of an asymmetric network or a concurrent network. In the method, firstly bearable bandwidth of the network and the actual processing bandwidth are estimated; when the packet loss or the packet retransmission occurs, if the bearable bandwidth of the network is larger than the actual processing bandwidth, the cause is considered to be the low packet processing of the sending terminal and the receiving terminal, and a lower priority is given to the confirm (ACK) packet. When the packet loss or the packet retransmission occurs, if the bearable bandwidth of the network is smaller than the actual processing bandwidth, the cause is considered to be the network congestion, then the packet is given and confirmed a higher priority; and the transmission rate of the confirm frame is adjusted according to the priority grade of the confirm packet. The present invention opens up different grades of green channels for the confirm packet, to avoid the confirm packet-intensity phenomenon, and the network congestion problem caused by the confirm packet-intensity is fundamentally solved, and the network security hidden trouble caused by losing the control of the confirm packet is avoided.

Description

Technical field [0001] The present invention relates to a method for accelerating data transmission in a communication network, in particular to a method for accelerating data transmission by flexibly using TCP protocol acknowledgement (ACK) packets to achieve the characteristics of asymmetric and multiple concurrent TCP / IP network applications. It belongs to the technical field of network congestion control. Background technique [0002] Currently, Transmission Control Protocol / Internet Protocol (TCP / IP) has become a widely used standard communication protocol. Among them, Internet Protocol (IP) is used as a network layer protocol to provide "data packet" delivery services, and Transmission Control Protocol (TCP) is used as a transport layer protocol to build connection-oriented transport layer services on the basis of data packet delivery services. [0003] The Internet based on the TCP / IP protocol uses a connectionless end-to-end data packet exchange and provides a design mech...

Problems solved by technology

However, the asymmetric and multi-concurrent network represented by interactive peer-to-peer communication makes the existing network congestion control mechanism out of control. The main reasons are as follows: 1. The existing TCP congestion control mechanism responds 2. Network asymmetry (NetworkAsymmetry) is the main reason that causes network congestion, and the existing method for improving TCP performance is still first-come-first-served under the principle of best effort (Best Effort) for different applications ( FirstIn First Serve), the problems caused by network asymmetry have not been substantially resolved; 3. The TCP congestion control mechanism is mainly a static method with "prevention" and "recovery" measures at the source, tracking data transmission Poor ability and poor adaptability to changes in data attributes of different network applications

Therefore, the existing congestion control technology does not fully consider the technical characteristics of asymmetry and multi-concurrency in the Internet, and has little effect on solving the problem of network congestion caused by asymmetry and multi-concurrency characteristics.
