Traffic control method, system and device, and computer readable storage medium

Abstract

The invention relates to the technical field of computers, and particularly relates to a traffic control method, system and device, and a computer readable storage medium. According to the method, thecurrent number of tokens is compared with a required transmission bandwidth, when the bandwidth is sufficient, a compression algorithm with a low compression rate is adopted to reduce the loss of data information entropy, when the bandwidth is limited, a compression algorithm with a high compression rate is adopted to adapt to the effective transmission of the bandwidth, no priority differentiation or weight packet management needs to be performed on message streams with different delays, the problem of invalid fragments caused by the bandwidth limitation is avoided, the situation in the traditional abandoning mechanism that a large number of messages are directly abandoned and requested for retransmission, resulting in great jitter of the network transmission rate, is avoided, it is ensured that in a network with a variable packet length, when the data input amount is greater than the supervision traffic, the data packets with different lengths can pass at an equal probability without complicated overall scheduling, it is ensured that fragments transmitted on the link are all valid while accurately limiting the traffic, so that the message abandoning probability is reduced and even eliminated, and the times of message retransmission are reduced on the premise of making full use of the bandwidth.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a flow control method, system, device and computer-readable storage medium. Background technique [0002] With the rapid development of computer network technology, it has a great impact on the current TCP network performance. The traditional TCP protocol was proposed based on the early network environment. The sender judges the occurrence of data message loss based on repeated ACK responses / acknowledgments, and interprets such loss as network congestion, and then uses additive, multiplicative, and subtractive methods to detect the occurrence of data packet loss. Adjust its own congestion window. [0003] The function of flow control is to limit the flow rate of a connection entering or leaving a certain network. When the packet flow of a certain connection is too large, the packet can be discarded or the priority of the packet can be reset, so as to achieve The purpo...
