Abstract

The invention provides a communication network delay jitter smoothing method, device and system. The method comprises the steps that a receiving module clears a forward delay threshold and a backward delay threshold at the beginning of initialization time; each business flow fragment is performed within the initialization time; and when the maximum value of the forward delay real-time value corresponding to the current business flow fragment and the backward delay threshold corresponding to the current business flow fragment is greater than the current value of the forward delay threshold, the current value of the forward delay threshold is replaced by the maximum value. Therefore, the delay threshold after the end of initialization is determined at the end of initialization and applied to delay compensation so that bidirectional asymmetric delay jittering can be substantially reduced, and the problem of abnormal user communication caused by excessive jittering can be prevented.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for smoothing delay and jitter of a communication network. Background technique [0002] With the rapid development of today's network technology, communication networks are gradually developing towards centralization, complexity, and intelligence. In communication network networking, with the increasing number of network devices, the performance of network devices and the relationship between The coupling degree is required to be higher and higher. Usually, the communication network provides two-way traffic transmission services. It is inevitable that there is an asymmetric delay between the forward traffic flow direction and the reverse traffic flow direction (English full name: Asymmetric delay), that is to say, there is asymmetry between the delay generated in the direction of forward traffic flow and the delay generated in the direct...
