Link packet drop rate control method and system based on terminal

Abstract

The invention relates to a control method for link packet discard rate based on the terminal and a system thereof. The method comprises: a packet which is transmitted from a local host computer to a remote host computer is acquired at the network layer, and the IP address of the remote host computer is recorded; the local host computer transmits a detection packet to the remote host computer according to the IP address of the remote host computer, the remote host computer obtains the average discard packet intervals of the current link according to the detected data and returns the average discard packet intervals of the current link to the local host computer; the local host computer obtains the network status rank of the current link according to the average discard packet intervals of the current link and the preset network status rank quantization table, and adjusts the link packet discard rate of the current link according to the network status rank of the current link and the preset packet discard rate distribution table; and the network status rank quantization table contains the corresponding relation of the average discard packet intervals and the network status rank. The invention can avoid the waste of network resources, and effectively improve the working efficiency of network.

Description

technical field [0001] The invention relates to the field of link packet loss rate control of multimedia services, in particular to a terminal-based link packet loss rate control method and system. Background technique [0002] Link packet loss rate control technology is usually used to adjust link bandwidth and reallocate resources. Effective and real-time adjustment of link packet loss rate is an important part of the entire link control technology. The traditional link packet loss control method is mainly based on two strategies: one is to add a link packet loss and control strategy to the original router, set the priority level of the service flow according to the user or service type, and uniformly control the current flow through the link. The data flow on the path is analyzed. When a link is congested, the overcrowded bandwidth will be readjusted according to the pre-strategy, so that resources can be used reasonably. This method often needs to modify the original c...

However, RTP and RTCP only support some multimedia audio and video services, and other services such as audio and video services or file transfer services independently developed by some instant messaging software are not well supported; at the same time, algorithms based on RTP / RTCP protocols are usually used as Therefore, all existing audio and video services of end users must support a set of policies stipulated by the RTP / RTCP protocol, which will inevitably lead to a significant increase in the workload of application development and improvement and program work Efficiency is reduced to a certain extent
