Media stream link intelligent selection method and device based on SDN

Abstract

The invention discloses a media stream link intelligent selection method and device based on an SDN. The method comprises the steps that an SDN is deployed between every two video monitoring management server nodes; a video monitoring management server needs to pass through the SDN when establishing a media stream negotiation signaling; the video monitoring management server carries server key information in response information of signaling negotiation; the SDN obtains the information from the response signaling message, judges the quality of the media stream link according to the information, and automatically discharges the priority, so as to intelligently select other unobstructed links when the establishment of the media stream link fails, thereby achieving the effect of guaranteeingthe successful establishment of the media stream link as much as possible under the condition that a user cannot perceive the establishment of the media stream link.

Description

technical field [0001] The invention belongs to the technical field of media stream forwarding, and in particular relates to a method and device for intelligently selecting media stream links based on SDN. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. With the development of the video surveillance industry, the media streaming link is no longer a single link in the past (for example: before a camera can only be shared with the upper-level domain through one lower-level domain, it has gradually developed into a camera that can pass through multiple Domains are shared to the same upper-level domain, so there can ...

Problems solved by technology

[0004] Although the problem of media stream link selection can be solved by manually switching links, it undoubtedly requires the user to operate one more time, and it will cause the user to fail at least once experience; in addition, the first failure must complete the interaction of the entire signaling process and return to the highest-level domain before the user can perceive it, which will cause a delay in the establishment of the media stream; moreover, when the user next operation may still fail Select the failed link, because there are a large number of camera points on a platform, and it is unrealistic for customers to remember which link at which point is unobstructed, and the user experience is poor
