Embodiment Construction

[0029] The present invention will be further described now in conjunction with accompanying drawing.

[0030] refer to figure 2 , the TCP congestion control method for bandwidth reservation network of the present invention comprises the following steps:

[0031] Step 1), detecting the current available bandwidth in the network link, the minimum round-trip delay of the TCP connection, and the average packet size of the TCP connection.

[0032] For a TCP connection, the size of each data packet transmitted in the connection and the round-trip delay of each data packet can be measured, so according to the historical data of round-trip delay and data packet size, the round-trip minimum time can be obtained latency and average packet size. The available bandwidth of the link can also be measured through existing technologies.

[0033] Step 2), based on the available bandwidth, minimum round-trip delay and average packet size obtained in step 1), calculate the start threshold T ...

Abstract

The invention relates to a TCP congestion control method for a bandwidth reservation network. The method comprises the steps of detecting the current usable bandwidth in a network link, the minimum round-trip delay for TCP connection, and the average data packet size for TCP connection; calculating the starting threshold T of a TCP sliding window according to the usable bandwidth, the minimum round-trip delay and the average data packet size; setting the initial size of the TCP sliding window as the starting threshold T and directly entering the congestion avoiding stage; reducing the size of the current congestion window to be T and reentering the congestion avoiding stage once packet loss or timeout occurs during data packet transmission.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a TCP congestion control method for a bandwidth reservation network. Background technique [0002] The transmission control protocol TCP (Transmission Control Protocol) is widely used in the fields of network and computer communication, and its main feature is the reliability of data transmission. In recent years, with the rapid development of computer network, computer network is no longer limited to the original wired and single homogeneous network, but presents a highly heterogeneous trend. In order to use network bandwidth more efficiently and improve throughput, domestic and foreign scholars have optimized specific networks such as high-speed networks and wireless networks that are currently widely used in recent years, such as BIC, FAST, and CUBIC algorithms for high-speed networks. ; Algorithms such as Veno and Westwood for wireless networks. In actual networks, ther...
