Method for detecting network transmission condition and related device

Abstract

The embodiment of the invention provides a method for detecting the network transmission condition and a related device. The method for detecting the network transmission condition can include the steps that a first communication device measures and calculates a transmission state characterization parameter for characterizing the network transmission state between the first communication device and a second communication device; if the transmission state characterization parameter meets a preset condition, the first communication device sends real-time transmission protocol messages to the second communication device, wherein at least one of a transmission rate adjusting command and the transmission state characterization parameter is carried in message headers of the real-time transmission protocol messages, and the transmission rate adjusting command is determined based on the transmission state characterization parameter. According to the technical scheme of the embodiment, the estimated accuracy of the available bandwidth of the transmission end network is easily improved, the bandwidth using rate is further improved, and delay and blocking are reduced to improve the user experience.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for detecting network transmission status and related equipment. Background technique [0002] The available bandwidth of the network is the maximum number of bits that the network can transmit in a unit of time. Among them, when the amount of data to be transmitted per unit time exceeds the available bandwidth of the network, problems such as packet loss and delay will be introduced. In application scenarios sensitive to packet loss and delay (such as voice / video calls, etc.), the sending end needs to estimate the available bandwidth of the network to ensure that the bandwidth occupied by sending data is lower than the available bandwidth of the network. [0003] In applications such as VoIP (Voice over Internet Protocol), due to high real-time requirements, user datagram protocol is usually used as the underlying transmission protocol. User datagram protocol is...

Problems solved by technology

[0005] In the process of research and practice of the existing technology, it is found that the sending end estimates the available network bandwidth based on the transmission state characterization parameters carried by the RTCP message from the receiving end, and the estimated available network bandwidth is often different from the current actual available network bandwidth. There are certain discrepancies, which affect bandwidth utilization to a certain extent, and may increase delays and freezes and affect user experience
