Embodiment

[0048] figure 2 is a wired / wireless network topology with bottleneck links, where S i is the data sender, R i for the router, d i is the data receiver.

[0049] Let the transmission delay T p =0.01s, the data packet size is 500 bytes, the wireless bottleneck link bandwidth C=250packet / s (1Mb / s), the sending and receiving node bandwidth is 2500packet / s (10Mb / s), the router cache size is 300packet, expect Queue length q 0 =100packet, number of TCP data sources N=30, link packet loss rate p l =0.1, the simulation duration is 100s.

[0050] calculate

[0051] So M(Z -1 )=203.8+407.6z -1 +203.8z -2

[0052] N(Z -1 )=7.56-7.2z -1 +1.5z -2

[0053] Solve the Diophantine equation N(Z -1 )E(Z -1 )+F(Z -1 ) = 1 get

[0054] E(Z -1 )=1

[0055] F(Z -1 )=-6.56+7z -1 -1.5z -2

[0056] The network congestion control rate is

[0057]

[0058] Tried contrast method (traditional congestion control algorithm) and the method of the present invention respectively i...

Abstract

The invention relates to service quality optimization of a wire / wireless network, and discloses a congestion control method for the wire / wireless network. The method comprises the four steps of establishing a wire / wireless network topology structure, setting feature parameters of the wire / wireless network, carrying out calculation to obtain a network congestion control rate, and carrying out congestion control on a bottleneck router. The method is applicable to the wire / wireless network mixed architecture network; for a real-time streaming media data application occasion, the better convergence is maintained for queue length; the delay change rate in a data packet transmission process is relatively low; and the network service quality is relatively high.

Description

technical field [0001] The invention relates to the optimization of wired / wireless network service quality, in particular to a network congestion control method based on minimum variance control. Background technique [0002] As the supporting infrastructure of the information society, the Internet has become an important indicator for measuring national technological innovation and economic competition. With the rapid development of technologies such as ultra-high-speed optical communication, wireless mobile communication, large-scale access, and ubiquitous Internet, and the continuous innovation of new applications such as Internet heterogeneous integration, mobile computing, and pervasive services, people's expectations for Internet functions, performance, Expectations for quality of service, controllability and reliability are increasing. [0003] In terms of service quality, the existing Internet does not provide service quality guarantee measures for non-real-time dat...
