Embodiment Construction

[0024] The core idea of ​​the present invention is: set the threshold value of the maintenance parameter of the transmission link, when there is a link with a better performance index than the current transmission link of the data stream, compare the maintenance parameter of the current link with the set maintenance parameter threshold, Whether to adjust the current transmission link is judged according to the comparison result.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] see figure 2 As shown, it is a flow chart of the first embodiment of the method for adjusting a data stream transmission link disclosed in the present invention.

[0027] Step 201: Set a threshold of difference degree of link performance.

[0028] There can be many transmission links for a data flow start...

Abstract

This invention discloses a method for adjusting data flow transmission links including designing a holding parameter threshold value of the transmission link to get the holding parameter of the current transmission link, when the property target of other links is better than the current link, the holding parameter of the current transmission link and its threshold value are compared to determine if the data flow transmission link should be adjusted. This invention also discloses a device including a communication module used in interacting with the routers in data, a transmission link holding module used in designing the holding parameter threshold value of the transmission link and a deciding module determining if the transmission link of the data flows should be adjusted based on the data flows provided by the routers, information of the link and the holding parameter threshold value.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for adjusting a data flow transmission link and an implementation device thereof. Background technique [0002] The existing intelligent routing technology can detect various performances of data flowing through a specific outgoing interface to the destination on multiple interfaces, such as data delay, packet loss rate, or data jitter and other parameters. After the performance is detected, a certain intelligent algorithm is used to adjust the transmission link of the data stream, and select the optimal link to meet the specific needs of the data, such as the image data delay is small, the voice data jitter is small, etc. [0003] E.g figure 1 The schematic diagram of the data stream transmission link is shown. The image data flow 1 can reach the ISP (Internet Service Provider) through both the outgoing interface L1 of the router R1 and the outgoing interface L2 of t...
