Example Embodiment

[0041] The overall process of the present invention is as figure 1 As shown, the data packet is intercepted first, and then relevant information is extracted to establish the link information management table; at the same time, the network status is continuously detected on the communication link, and the link packet loss rate is adjusted according to the detection result, and Update the link information management table in time.

[0042] When the local communication host and the remote communication host perform multimedia communication, perform the following steps:

[0043] a. At the network layer, the data packets sent from the local host to the remote host are intercepted, and the link information management table is established to manage the data packets.

[0044] b. Perform real-time network link status detection during the above communication process, and return the detection result.

[0045] c. According to the detection results provided in b, data packets are scheduled a...

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...
